How To Make a 3D Printed Concrete Stamp

A section of concrete stamped with the phrase "Macklin Manor. Est 1989"

Pressed into the concrete outside the newly remodeled Holy Trinity Missionary Baptist Church in Youngstown, Ohio is a distinctive embossment, “Macklin Manor, Est: 1989.” The notation was added to honor the church’s long-serving pastor, Reverend Lewis Macklin II, a much-beloved community leader in Youngstown. What isn’t obvious about that marker however, is that the concrete stamp that made it was 3D printed.

Concrete stamping has been around since the 1950s, and the earliest stamps were made of sheet metal or even wood. Modern concrete stamps are made from molded polyurethane and have patterns that can make concrete look like brick, tile, or stone. Custom stamps are traditionally used to add company logos, building numbers, etc., but the lead time to create one is upwards of one to two months. What do you do if you need a concrete stamp and only have a few days before the cement trucks arrive? You call someone with a really big 3D printer, and in Youngstown, for Holy Trinity Church, that person was Pam Szmara.

We recently spoke to Pam Szmara with Pamton 3D Printing about the Macklin Manor project, and she shared this how-to, modified from Formlabs instructions, for how you can make your own custom concrete stamp.

Here's Pamton 3D's advice:

We recently completed a project that required us to design and 3D print a stamp capable of personalizing a concrete stone at Macklin Manor in Youngstown, Ohio. We enjoyed the project and are excited to have the capability to make small or large personalized concrete stamps for our clients’ residential and commercial projects.

So, how do you do it? How can you use additive manufacturing technology to help you personalize or preserve the history of your buildings, projects, or events?

Here’s a quick rundown of the process.

1. Draw your stamp digitally using a vector file format. You can use a software program like Adobe Illustrator or a free program like Inkscape to do this. When you have the design complete, save it as a Scalable Vector Graphic (.SVG) file, which can be imported into a CAD software to make the 3D model. Alternatively, sketch the drawing directly in the CAD software.

– The final design must be mirrored so that the stamp itself is the reverse of what will appear on a stamped surface.
– Use large, widely-spaced lettering and thick details so that the features read well in concrete.

2. Convert the vector design into a 3D model. Using 3D modeling software like Fusion 360, Onshape or Tinkercad, convert your two-dimensional .SVG file from a curve to a mesh. Then, extrude the mesh to make a 3d shape.

3. Add a backing plate. Add a rectangular backing plate to the shape. This will give you a flat, sturdy surface to stand on as you press the design into the concrete. We recommend the design fill up 80% of the rectangle.

"...it will take half a day or more to print your stamp, so crack open a beer and relax."

Pam Szmara

4. Optional: Add a stamp handle. A handle will help you easier position and remove the concrete stamp, however it will make your stamp require support material when you print it, so this is why it’s optional. The handle should be a C-shape attached to the opposite side of the backing plate from your design. Make the handle thick and robust, so it won’t snap when it has to resist the suction of the concrete.

5. Export the file as an .STL file and slice your print. For the Macklin Manor project, we used a good quality PETG to print the stamp. You can also use a TPU filament like Ninjaflex Cheetah, to make the stamp flexible, but that does have a higher material cost. Whatever you go with, position the STL to print with the handles down, and the design facing up. Slicing at a standard resolution (0.3mm layer height or similar) is perfect for a concrete stamp.

6. Start the presses. It’s go time. Print your stamp on a large format 3D printer, like the re:3D Gigabot 3+ we use at Pamton 3D. Depending on the size of your stamp, it will take half a day or more to print your stamp, so crack open a beer and relax.

7. Start stamping. Now’s the time you’ve been waiting for. When pressing it into concrete, stand on the stamp if necessary, and if you mess up, pull it out, hose it off, and try again! You can use your new concrete stamp for whatever you want. You’ll be able to make your mark on all kinds of business or personal projects.

Not wanting to make it yourself? Next time you need a custom stamp for your concrete project, we’re ready to help. Get in touch with Pamton 3D for a free quote or to talk about your 3D printing needs (but maybe give us a bit more than a couple days’ notice!)

Introducing a New Kind of Paddle Board

A man sitting on a paddle board back to the camera. He is rowing with paddles attached to a track.

In 2014, Guy Chaifetz of West Palm Beach, FL had an idea: what if you combined the versatility of a rowing machine, with the full body workout from cross-country skiing, all while being able to enjoy ocean breezes outdoors on your paddle board. He’d been exploring this product idea for the last seven years, forging through multiple design iterations, overcoming investment hurdles and production stalls until recently, when he successfully launched the Supski Paddle System.

The Supski System attaches to a standard or inflatable paddle board and uses a sliding rail mounted with a modular pole and paddle. The versatile design allows the user to row their paddle board in a variety of positions, modifying their stance as needed to isolate muscle groups and achieve a full body workout. While producing his final prototype, Guy reached out to the re:3D Contract Printing team to 3D print a part he was finding too difficult and expensive to manufacture elsewhere: the Quad Rail Track.

Using the extra large bed of our Terabot 3D printer, re:3D manufactured the 64” rails in a series of 23 hour prints with white ABS filament.

It’s been a long journey for Guy Chaifetz, whose professional background is in video editing and production. He debuted an earlier prototype at Surf Expo in 2015, but despite the positive response from attendees and beta testers, manufacturing hurdles held him back from releasing his product until now.
Guy believes that with the success of the Supski launch, he’ll be able to share it in paraplegic communities to increase accessibility to paddle boarding. Additionally, a future add on includes a sliding chair for regular rowers. Guy hopes to host annual Supski paddle board races, and his ultimate goal would be to have the Supski be part of the Paralympic and Olympic Games.

Want a Supski of your own? Click here to find out how to order.

re:3D salutes Guy Chaifetz for his persistence and tenacity in bringing his dreams to market. If you have an idea you want to transform into reality, our Design and Contract Printing team are here to help you.

Happy Printing!

re:3D Supplies Parts for Testing America Makes AMCPR Exchange

A gigabot 3d printer, printing a black 8 inch coupling.

re:3D had the honor of helping to stress test AMCPR, America Makes’ new exchange for enabling rapid additive manufacturing production responses during times of crisis, like we did at the outset of the COVID-19 pandemic.

America Makes developed the AMCPR exchange to be a long lasting solution to host design files, review them for safety, and, when needed, distribute them to the US’s additive manufacturing community for production.

Part way through the development process America Makes reached out to members seeking participants to help test the exchange, and re:3D answered the call along with our peers in the 3d printing industry.

We took part in a mock-crisis scenario called Earthquakes Earn Enmity, designed to simulate a response to an earthquake which crippled water delivery systems, otherwise known as pipes!

Ironically just as we were kicking off the mock-crisis, we were faced with a real crisis here in Texas: A hard freeze dropped temperatures to record lows all across the state, and many lost power as the power grids failed to keep up with demand. Pipes burst and created a shortage of plumbing supplies. It illustrated in very real detail how important this AMCPR exchange can be where additive manufacturing can step in during crisis to quickly increase product supplies when traditional manufacturing has to wait to retool their factories.

We met over the course of two month to walk through testing. The first step was to design pipe couplings that could be successfully manufactured with 3D printing. This work was done by a team at the University of Texas at El Paso. The designs were reviewed by America Makes and validated by a separate team at UT El Paso who had not been involved in the original design work. They used the AMCPR exchange to submit and review and finally approve the designs for use on the exchange.

After the design process, re:3D stepped in as a supplier along with Rapid Application Group, IC3D, Stratasys and Markforged to 3D print the requested couplings. We downloaded the technical data package from the AMCPR exchange, reviewed it with our contract printing team, sliced the included stl files according to their required parameters, and produced three example couplings on Gigabot 3+ XLT out of ABS filament. The three couplings measured 2”, 4” and 8” in diameter. To complete the scenario we each mailed the printed couplings to ASTM International, who was acting as the requestor in our case.

Throughout the process, we advised America Makes on clarifications and revisions the AMCPR exchange needed to improve the usability and accessibility of the system. Things like the variables that different industrial FDM 3D printers have as far as materials, size, and slicing, as well as enhancements to communications and troubleshooting.

One of the highlights for us of helping test the system was participating in some final testing walkthroughs with our customer and fellow America Makes member Pampton 3D. We got to observe how the improvements that had been made in only a few short months eased Pam’s experience first using the AMCPR exchange.

Now that this testing is done and the AMCPR exchange is live, We invite you to join us on the exchange by creating an account to be a designer, supplier or a requestor, so that together with your skills and ingenuity, when we face our next crisis, we’ll all be ready.

How to Turn Your 2D Logo Into a 3D Print Using Rhino

Everyday we see logos wherever we go. Whether it’s a billboard, flyer, or even a blimp, there’s a good chance it has a logo. One place logos are appearing even more is on 3D prints. 3D printing makes it possible to design and print a variety of objects with a logo stamped right on it. Although it sounds complicated to turn a logo into a 3D print, the process is easy!

You may have seen our previous tutorial on turning a logo into a 3D print, but over the years we’ve come up with even more tips to help your logo shine. In this updated tutorial, you’ll learn how to take a logo from an image to a 3D print. In this demonstration we’re going to use Rhinoceros 3D, but there many tools including SolidWorks, Tinkercad, Fusion 360, or Onshape that could achieve a similar result.

Before you begin, you will need a vector file of your logo (usually in .ai, .dxf, .svg, or .eps format). If you don’t have a vector file, you can convert your raster file (.jpg, .png, .bmp) using an editor like Adobe Illustrator or Super Vectorizer. Online converters exist as well that automatically take your raster image and turn it into a vector image. In the tips and tricks section later, we will show you a third way to convert a raster file directly in Rhinoceros 3D!

How to Make a 3D Logo

Once you have your vector file, start Rhino 3D (or your CAD software of choice) and import your vector file. If your logo is flipped or upside down, you can use a simple mirror command to reorient the logo. Sometimes a vector file will leave a border when imported. Be sure to delete these border lines too! What you should be left with is the logo design you want to use.

Next, choose a shape you want your logo to live in. This can be whatever you want, so don’t be afraid to get creative! In our example, we are housing our re:3D logo inside a circle. Once you have your shape finalized, extrude it outward. The extrusion length should be around half to two-thirds the height of your logo. We will use this shape later to make a platform for our logo.

With your shape extruded, you now want to make your logo pop! You have a choice here, you can either extrude your logo outward or cut your logo inward. In our example, we extruded the re:3D logo out of the cylinder’s face. Be sure you don’t cut or extrude too far, or your logo will be hard to see on the final model. The example we have is a good distance for most logos if you’re unsure.

You now need to make your model solid. Although your logo may appear solid on screen, 3D slicing software will get confused if we don’t join together and solidify all the parts of our model. To join everything together, we perform either a boolean union or boolean difference to remove all the overlapping borders and make our model solid. This is important: if you extruded your logo from your shape, perform a boolean union. If you cut your logo into your shape, perform a boolean difference. Mixing these up could ruin the work you’ve put in so far!

Next, you need to rotate our shape how you want it to sit on a table. Rotate the model so the logo is facing slightly upward. Not only does this make it easier to see your logo, it also helps eliminate overhangs once you print it. Once you’ve positioned your logo how you would like it, look at your logo from the side and draw a horizontal line. Use Rhino’s trim command to cut through your shape and the cap command to seal the hole. For some CAD software, this step may look different.

You now have the basic shape of your tabletop logo! From this point, you can get creative and slice more off your model using the same trim and cap method. Depending on the design of your logo, you can use design features to support your model. For example, we use the shape of the re:3D hexagon to support our final model. Once you’re satisfied with your logo design, export it as a .stl file, slice it in your slicing software, and print it!

Here are a few tips and tricks we found when designing a logo print:

If you don’t have a vector file, you can use your CAD software to fix this! In Rhinoceros, import your logo by going to View → Background Bitmap → Place. This inserts your image on the plane and lets you trace out your logo using a sketch!
If you want your logo to sit up straight like a sign, extrude or cut your logo at an angle to eliminate any overhang issues.

A video of the process is also available below:

3d printing Design process

Rolling Out the re:3D Wind-Up Car

Written by: Brendan J. Towlson

How do we encourage creators to explore new concepts? Give them something to create! When re:3D’s Community Liaison, Charlotte Craff was thinking of ways to spread the message that 3D printing is the future of manufacturing on Manufacturing Day, she came up with the idea of allowing visitors to build something out of 3D printed parts.“We build machines all day; why not provide our guests the opportunity to do so as well?” The wind-up car build was conceived. And the best part: you can print and build it yourself!

Attendees of re:3D’s Manufacturing Day Open House had the opportunity to tour the factory, touch and feel 3D prints from around the world, learn about the different skill sets involved in operating this unique hardware company, and finally take home their very own wind-up car. The challenge, though, was that the cars were not pre-assembled. If visitors wanted a car, they had to put it together themselves.

This wind-up car was designed by Mike Battaglia in Rhinoceros 3D software. It is made entirely of 3D printed parts, which is a difficult feat to get right. There are 21 parts, including four wheels, two axles, a gear system, and a spring with a hand crank. Once printed and assembled, you can crank the spring to store potential energy, and then release the car to watch as it converts potential to kinetic energy, and transfers it through the gears to the wheels that drive the car forward. It is a simple concept, but getting the parts to work together was a test of our 3D printing skills, and Mike spent time adjusting tolerances to get it just right.

The cars printed for Manufacturing Day were made of PLA. We learned a lot about this material while designing the cars. For example, white PLA is very pigment saturated, causing it to behave differently when melting and cooling. Tolerances on each part had to be adjusted accordingly. We used up to six of our Gigabot® 3+ workhorses at a time running 36 hour prints continually over a period of two weeks to complete the prints. In the end, for the Manufacturing Day event, printing 56 complete cars added up to 1,176 total parts, 420 hours of print time, and 28 pounds of material.

Challenging 3D print builds like this produce something that is more than just a toy. “It’s meant to demonstrate that even simple machines are complex, fun and buildable by people of all ages,” Charlotte said, “and it’s meant to inspire young people to look deeper into how machines function.” 3D print your own Wind-up car by downloading the design from Thingiverse or Cults! Or buy the kit from us on Etsy

Innovating in The Time of Corona(virus)

The exponential spread of the novel coronavirus across the globe led to overwhelming demand on supply chains and disruptions to traditional manufacturing and distribution systems. Because of societal lockdowns and stay-at-home orders, a dire need quickly arose for locally fabricated, specifically focused and creatively sourced solutions to equipment shortages and emergency supplies. At home and across the globe, designers and engineers quickly mobilized into online, open-source prototyping groups to solve the challenge of a lack of personal protective equipment (PPE), ventilators and medical device accessories. 3D printing and additive manufacturing was an obvious go-to, with the ability to rapidly prototype and iterate on the fly, teams could utilize 3D printers to supply healthcare providers with equipment now, as soon as there were designs to print. The intention and needs were obvious and clear – to aid humanity and fill the gaps in supply chains – however, organizing volunteers and streamlining the process to avoid duplicate efforts was a daunting task.

As a company with a wealth of R&D project experience and long used to working as a distributed team, re:3D put out the call that we would prototype – for free – any life-saving devices or PPE in order to expedite review by medical professionals. We are conscientious contributors to the open source design community for COVID-19 response. We take a First, Do No Harm approach to any design work we do for this effort, meaning that it needs to be designed with input from, and in partnership with, the individuals who will utilize any equipment we prototype. We will not create anything that gives a false sense of security, but is ineffective or harmful. Our medical providers on the front lines are in need, and we are honored to take on the challenge.

Face Shields

In two overlapping efforts, we prototyped a design for a 3D printed face shield with full visor coverage and an adjustable zip tie style latching mechanism. The inquiry started in Puerto Rico. Vicente Gascó, our friend and colleague from Tredé and Engine-4 shared he had a supply of 4000 clear plastic lenses for face shields, but no visor to which they would attach to the head. Armed with only the measurements of the lenses and aided by an idea from assembly guru and NASA technician Andrew Jica in Houston, Brian Duhaime, our mechanical engineer in Austin, and Alessandra Montano, our graphics designer in Puerto Rico, pumped out five different iterations of a face shield in only 48 hours.

Vicente and Luis Torres, co-founder of Engine-4, pulled our Puerto Rico Gigabot out of Parallel-18 and added it to the existing Gigabot at Engine-4. Gigabots in Austin and in Puerto Rico printed out iterations of the designs for testing.

In Houston at the same time, CTO Matthew Fiedler, mechanical engineer Helen Little and community liaison Charlotte Craff were meeting with doctors from a local hospital to discuss their needs for a face shield. Knowing that vetted, open source face shield designs were already available, the group reviewed designs by Prusa, Lazarus3D, Budmen and Professional Plastics. The Houston team 3D printed existing options for the doctors to test, but the designs didn’t meet all of the doctors’ needs:

Lightweight, fully closed top
Reducing the air gap between lens and chin
180 degree lens coverage
Limit number of parts to reduce need to source materials in short supply

Knowing that supply chains were disrupted and very little raw materials were available in a timely manner, re:3D conferred with Professional Plastics and determined that plastic sheeting supplies were well behind schedule, but that there were excess pre-cut face shield lenses available. Again, re:3D opted to prototype to existing, local supplies, keeping stress off of traditional supply chains and getting creative with what was available.

Over the next week, Helen built on the work done for the Puerto Rico design, integrated the needs of the doctors and iterated ten different versions of the face shield while working from home and rarely getting to hold a print in her hands. The result is a single print, face shield with an adjustable latching mechanism. It’s designed for 180 degrees of protection and comfort without the addition of foam padding. It has the approval of the hospital’s Infection Control and is currently available at the National Institutes of Health 3D Print exchange for COVID-19 Response. https://3dprint.nih.gov/discover/3dpx-013504

Hands-Free Door Pulls

Eliminating unnecessary shared contact surfaces is imperative, especially in buildings where essential workers are operating to continue necessary services. Our team includes multiple military service members. One of our reservists was activated when she sent out a call back to our team to make some hands-free door pulls to use on the base. Aided by Matthew Fiedler, Mike Battaglia, our designer in Austin, and Brian Duhaime went to work prototyping hands-free door pulls for lever-style and bar-style door handles.

These designs were drafted before we had dimensions for either of the door styles, so had to be modeled in such a way to enable incremental dimensional adjustments while preserving the models’ shapes. During her free time, the service member sent feedback on the first versions via pictures and notes, and Brian and Mike iterated the changes remotely, melding organic shaped and attachment options into single print solutions.

The hands-free door pulls are now successfully in use on base, protecting our military personnel as they work to respond and aid COVID-19 efforts. These models are available for download here https://3dprint.nih.gov/discover/3dpx-013825 and here: https://3dprint.nih.gov/discover/3dpx-013822

From Intubation Box to Drape Stands

As a 3D printer manufacturer, we are understandably advocates of 3D printing use in manufacturing. However, we recognize that not all innovations require, or are best served by, an exclusively 3D printed solution. As we do much of our manufacturing in-house, including machining parts on our CNCs, we can apply rapid prototyping principals to traditional manufacturing methods. Take the example of an aerosol or intubation box:

We were contacted by an anesthesiologist based in Austin about modifying such a box, used to protect doctors and nurses from aerosols released when intubating a patient. The doctor’s main concerns were ability to clean and the need for a “helper” hole. This equipment needed a curved, clear surface rather than sharp corners where germs could hide. We offered to prototype using polycarbonate sheeting and an aluminum framework available in our machine shop. In this case, the request for aid evolved before we produced a prototype. The anesthesiologist reported that the existing boxes were unwieldy and took up too much space, so instead requested a solution for supporting clear plastic drapes to achieve the same purpose and be easy to store. Matthew Fiedler proposed a combined 3d printed base and a bent aluminum frame for the project. Design work is ongoing and we will update this post as the prototype develops.

Tell us about the design you are printing.

After learning about a need for PPE, we started printing a derivative of the 3DVerkstan visor design for face shields that could accept pre-cut shields that had been donated. We chose that design because it was the fastest to print. It was nice to see along the way that it got NIH endorsement. Our expanding print farm of Gigabots & Prusa printers is located at Engine-4, and includes local Gigabots that Parallel 18, Daniel Varela, and Atlantic University (once it clears customs!) loaned to help bolster production.

Tell us about the design you are printing.

When I heard about a potential shortfall in PPE supplies at New York area hospitals, my first reaction was to research mask/respirator models but soon realized they were not an ideal candidate for FDM printing. Face shields are also in short supply and there were a couple of designs that looked promising. I downloaded and tested several candidates before I found a design on March 26th by Swedish 3DVerkstan which they had just released in the wild, I soon I discovered that Weill Cornell and several other institutions had adopted this model because of its simplicity and ease of assembly. It consists of two components, a 3D printed head strap and a clear plastic shield which can be easily fabricated using letter size acetate sheet .005 or thicker and a standard 3 hole punch.

We started working with the design from Prusa, which looked like it was carefully researched and tested and approved and it worked well, so we printed about 400 of those in total. We’ve recently moved on to the 3DVerkstan design, which takes half the time to print so it helps us increase our production. In addition to these, we’ve also designed a copy of some safety glasses they use at the hospital, which print even quicker and use less material.

What material are you printing with?

We’re printing mainly with PLA because that’s what we have, and it’s easy to work with. We’ve also used a bit of PETG and some ABS because that’s what we had, and it should work fine according to the Prusa and 3DVerkstan websites.

Who are you printing this design for?

We’re printing for the two main hospitals on the island, Horacio Oduber Hospital, and ImSan (Instituto Medico San Nicolas), as well as the department of health who are doing the testing (DVG, Directie Volksgezondheid), the psychiatric hospital organization (Respaldo), the union of family doctors and dentists, as well as individual health workers including nurses and family doctors who ask us specifically.

Tell us about the design you are printing.

We are printing a head banding component of a protective face shield. It is based on a design by Prusa, and had been approved by the Czech Ministry of Health for use to help fill the void of PPE (Personal Protective Equipment). The version we are printing is a redesign by TXRX Labs and part of a volunteer effort that they had organized to help with our own local need for PPE during this worldwide COVID-19 pandemic. We are excited to see local additive manufacturing step up to a shared worldwide call, where intellectual property and design ego take a back seat to provide real time evolving, useful, and needed objects for humanity.

What material are you printing with?

We are printing with PLA from re:3D, always our first choice for on hand reliable material. We are printing 24×7 on our original (but upgraded a little) Gigabot #21! Each part is around 1hr and we are doing at least 6 units at a time.

Who are you printing this design for?

These prints are for our Houston area doctors, nurses, and staff on the front lines of the COVD-19 pandemic in hospitals and stations that are in need of PPE or anticipate a need in the coming days/weeks. Our parts are delivered to TXRX labs in Houston and are assembled with laser cut shields and elastic bands to complete the product and are distributed from there.

Where are you located?

We are located in Baytown, TX in our home office. My wife (Roya Plauché) and I (John Plauché) make up plodes_® studio. We are a Texas based multidisciplinary design firm that draws from a coalescence of art, product, and architectural design. Our products are varied, authentic, minimal, and distilled with rigorous process to a balanced purity. Currently our best sellers are fire pits, so check them out and make a backyard escape for yourself while we are in this ‘Great Stay’. Help flatten the curve and please stay home as much as possible!

Where can people sign up to assist with this effort?

We could use local area volunteers to pickup parts from us and drop to TxRX labs when we get 50-100 units at a time. Please email info@plodes.com with subject “TXRX pickup”. And please everyone visit TXRx’s go fund me at https://www.gofundme.com/f/txrx-manufactures-protective-medical-equipment and give what you can!

CM Welding & Machine | Corey Mays

Midland, TX, USA

Tell us about the design you are printing.

We were printing a prototype ventilator splitter designed by Texas Tech and UT Permian Basin to allow up to 4 patients to use one ventilator. The first run has been sent for testing and we are waiting to hear back on that part. In the meantime we started reaching out to local medical personnel and some of the rural areas to see what needs they might have. We found the biggest need was for face shields. We chose a simple open source design and have been printing these 24/7 to fill these needs.

What material are you printing with?

For the ventilator splitter I chose PETG material and we are printing the face shield headgear out of PLA.

Who are you printing this design for?

Any medical personnel in need of face shields.

Where can people sign up to assist with this effort?

I encourage anyone with a 3D printer to contact your local medical personnel or local universities of schools to help fill immediate needs there. Also, go to www.matterhackers.com and sign up for the COVID-19 response team. They will send out requests and files.

What has it been like for you working on this project?

It’s been exciting to be able to work on this project. As a manufacturer and mechanical designer I’m a problem solver by nature so being able to have the capability to help has been really fun and exciting! The Gigabot has been absolutely rock solid through this project. The larger print bed allows us more freedom to run different part arrangements so that we do not have to have someone here 24/7 to watch the machine. With the face shield head gear, we start a run of 6 in the morning and that run is ready to be pulled off by 5 pm. We then start a run of 8 that is ready when we come back in the following morning. I don’t think it has been off in almost 2 weeks and still going strong!

The Kinkaid School | Jeff Diedrich

Houston, TX, USA

Tell us about the design you are printing.

The design is from TX/RX, a non-profit makerspace here in Houston. My first prints were based on a single design where I could fit 9 on the bed. Then Patrick Ferrell @PBFerrell told me about a stacked design with 9 high which meant I could do 81 at a time. This was a 110 hour print.

What material are you printing with?

PLA

Who are you printing this design for?

These are being printed for TX/RX

What has working on this project been like for you?

I am fortunate to work at a school with a Gigabot, and our head of school, Dr. Ed Trusty, was more than happy to allow me to use the school’s equipment and material to give back to the community.

Doug Mockett & Co | Paul de Leon

Manhattan Beach, CA, USA

Tell us about the design you are printing.

We started printing designs a friend of mine sent to me – all from Thingiverse. After printing for a few days, I realized our two Gigabots weren’t going to be able to catch up with the demand, so Carlos and I played with the settings and got the print time down to 28 mins per visor for open visors, 35 mins for closed top visors (some hospitals preferred closed visors) which still wasn’t enough. I saw a post by a company from another country which did in house casting. That was clever so I thought we should do the same. I contacted our local silicon and plastic supplier for molding instructions and to buy materials to make silicon molds. I designed a closed visor that could work with molding and casting. I printed a few versions using our Gigabot 3+ and used that print to create a silicon mold.

We are also printing ear savers (mask extenders). These seem to be quite popular.

What material are you printing with?

PLA

Who are you printing this design for?

Local hospitals and nursing homes:

Torrance Memorial Hospital, CEDARS SINAI & Providence Little Company of Mary (earsavers), Long Beach Memorial Rehab, and other local clinics.
Delano Hospital, VA Palo Alto and other smaller clinics in other states

What has working on this project been like for you?

It has been a privilege and an amazing team experience to be able to create something to help in this time of need. It means a lot to our team to be a part of this project and donate to healthcare providers.

Compendium Federal Technology LLC | Stuart Langford

Lexington Park, MD, USA

Tell us about the design you are printing.

Originally, we were going to make frames and donate them to Makers Unite in Baltimore, MD. At the time, they were asking us to use the Prusa v.RC2 face shield design. In the meantime our CEO was communicating with local first responders, and Medstar Saint Mary’s communicated that they were running low on face shields. We used the Prusa v.RC2 face shield, but we made some minor changes so they would print faster. The straps are our design. We tried several designs including the strapless, but we received the best feedback from the modified Prusa v.RC2.

What material are you printing with?

PLA for the frame. NinjaFlex TPU 85 for the straps. The clear screens are made from clear acetate or PVC sheets.

Who are you printing this design for?

Medstar Saint Mary’s Hospital, Charlotte Hall VA Clinic, several nursing homes and private practices.

What has working on this project been like for you?

It has been busy, but rewarding. I wasn’t the only person contributing. My CEO John OConnell did the leg work, and my coworker Cedrick La Marca assisted with the CAD designs and resin printing. In addition to the face shields, we also printed spare ventilator parts for Saint Mary’s Hospital. Everything was donated free of charge.

Update May 29, 2020

It’s been a month since our last update, and our COVID-19 response is still going strong! On May 12, we were honored to receive an honorable mention in the America Makes Fit to Face – Mask Design Challenge. Designer Mike Battaglia and Engineer Samantha Reeve submitted a mask in two sizes designed to be printed with NinjaTek Cheetah. We continue to collaborate with projects for supplying PPE and consulting on new solutions for face shields to ventilators because we understand that effective face protections is essential for keeping our employees and the general public happy and healthy.

Our Houston factory is still closed to the public, but our team remains committed to building your Gigabots and filling your supply orders and service needs.

Gigabot customers around the world are tirelessly supporting their communities and we are honored to share their stories. If you have been doing COVID-19 work, we’d love to hear from you!

AUSTIN UPDATE
Thanks to the efforts of so many groups in the city, the PPE needs for healthcare workers there have been met and we have wound down our collection boxes for 3D printed PPE.

HOUSTON UPDATE
As the city begins to open back up we have teamed up with Impact Hub Houston on PPE for the People, an effort to provide PPE to workers in minority and under-served communities who are at greater risk of critical illness from COVID-19. Please support this project by sharing, donating and letting local businesses know about the opportunity.

PUERTO RICO UPDATE
The PPE support work in Puerto Rico continues and the Gigabot collaboration at Engine-4 keeps churning out supplies for the island.

If you’d like to be connected to any local effort we would be happy to make introductions and provide resources. Please reach out to us at info@re3d.org.

Update: April 25, 2020

It’s hard to believe that two more weeks have past since our last post! We continue to aggregate and collect your PPE donations in Austin, Houston and PR. We also (just met the deadline for the America Makes Mask Fit Challenge). The final design will be posted to our NIH 3D print exchange tomorrow:)

We continue to be inspired by YOU, and welcome your pics and videos for future stories!

re:3D is working on a number of different projects related to 3D printing and COVID response. Our Houston factory is helping to support two efforts. The first is supporting the efforts of TXRX and the amazing maker-community organizing taking place around Houston. re:3D is donating 3D printed face shields as well as hosting a community donation box for makers in the Clear Lake area who are printing the face shields at home. At our factory, the batches are consolidated and sent to TXRX for assembly and distribution to hospitals and first responders in the Houston area. Second, the re:3D design team is prototyping a custom face shield design, in conjunction with doctors from Texas Children’s Hospital. The new design incorporates a pre-cut clear plastic face shield with a 3D printed holder/headband.

In Austin, re:3D is rallying the local maker community. While there are a number of people working on the 3D printed PPE issue in the Austin area, re:3D is hoping to help organize these efforts. The Austin team is designing hands-free door pulls and intubation boxes, and we will be releasing all of the 3D printable open-source designs that we have created, including face shields, door pulls and anything else we develop, free of charge. We are opening Austin community drop boxes at multiple locations where anyone who 3D prints can donate their COVID-19 parts. location information will be released as soon as it’s finalized.

In Puerto Rico, re:3D is supporting efforts led by Engine-4 on 3d printing face masks and ventilator splitters. Thanks to efforts by Parallel18, our Gigabot has been relocated to Engine-4 to print for this effort and we are hosting weekly calls for healthcare professionals, designers and makers to organize the community to support creating PPE unique to the needs on the island. We are connecting with every available Gigabot owner on the island to help them join the cause.

High-Voltage Innovation: Creating Tools and Training Models with a Utility Company

Here’s a question: when was the last time you thought about what happens when you flip on a light switch?

We take for granted this everyday miracle without much thought to what goes on behind the scenes to make the lights turn on. Only once the power goes out do people suddenly take notice of this invisible luxury that our daily lives rely on. Lighting our homes, charging our devices, refrigerating our food, powering hospitals and public transportation and the nation’s economy – life as we know it hinges on the seamless, invisible flow of electrons we call electricity.

But, perhaps, everyone once in a while, you have taken note – maybe while driving on the highway past towering transmission lines stretching as far as the eye can see – of the massive system around us that goes mostly unnoticed on a daily basis, and how little you know about how that system functions.

Today’s story may change that for you.

The electrical grid in this country is over a century old. The first commercial central power plant in the US – Pearl Street Station in Manhattan – opened in 1882 and served 82 customers.¹ Today, the US electrical grid is made up of over 7,300 power plants and 160,000 miles of high-voltage power lines, serving over 145 million customers.²

The focus of our story today is one of the largest of the roughly 3,000 utility companies keeping the lights on in the US. (Due to company policy they cannot disclose their name in external-company features and thus will remain nameless in this article).

Making safety a priority with hands-on training

Jim Patchen is a high voltage work methods specialist for said utility company. His job is to develop procedures on how to work safely around high voltage. His office is a veritable mini-museum of utility relics from a bygone era.

As equipment from the field has been retired over the years, he’s rescued treasures from a certain fate as scrap metal. Artifacts like ammeters, voltmeters, control switches, and molten and re-hardened piles of metal from errant tool mishaps start at the floor and line shelves up to the ceiling.

As for his collector’s habit, Patchen explains his motivation behind this essential preservation of history. “It is important to understand the legacy of this industry,” he says. “Early on, work methods and tools were quite primitive, but over time they have evolved. It’s good to know where you came from so that you know where you’re going.”

The job of every utility company is to generate electricity and transport it to customers. This is, of course, a highly simplified explanation, but the general flow is as such: electricity is created at a generator – taking the form of power plants, hydroelectric dams, solar panel arrays, or wind turbines – transported along transmission lines, and distributed to communities for end use.

Along the way are substations – the large, somewhat hectic-looking clusters of wires and electrical equipment you may notice while driving on the highway – which transform the electricity into high voltage for fast transport along transmission lines and into lower voltage for its final use in homes and businesses. Far from the chaos that they can appear to be to the untrained eye, substations are meticulously-organized, well-oiled machines that are crucial components of the electrical grid. And while designed for maximum safety of workers, they are also extremely high-voltage environments, which inherently pose a unique set of dangers to those in the vicinity.

“Working in a substation is difficult,” explains Patchen, “because it’s many, many circuits coming into one small location, so the high voltage environment is really concentrated. We have to work really [safely] around that to prevent injuries and incidents that could affect the grid.”

This particular utility company has over 1,000 substations in its service territory. As a work methods specialist, Patchen’s current role revolves around creating procedures to ensure the safety of workers in addition to the integrity of the grid and the power they’re providing to consumers. “If you make a mistake in a substation, you can impact thousands of customers,” he explains. “If I drop a screwdriver in a substation, I can take out 90,000 customers. So, everything we do is critical.”

Workers at the company go through a roughly three-year apprenticeship of rigorous training on how to work safely in such an environment. “Traditional training involves PowerPoints and lecturing,” explains Patchen. Unfortunately, he continues, the retention rate of knowledge taught in these sorts of settings tends to be abysmal. Their goal is to incorporate more tactile learning to keep students engaged throughout lessons.

There is always hands-on training out in the field for all students in the apprenticeship program, but the company wanted the ability to bring this type of learning into classrooms on a daily basis. They saw the value of using scale models of real-world equipment on which students could practice skills like protective grounding in a safe, unenergized environment. The models give students the opportunity to test their proficiency, and teachers the ability to confirm that their lessons are getting through and sticking. “They’re able to practice and prove their understanding of what they’re being taught,” explains Patchen, “and then you’re able to validate knowledge that way.”

Patchen began by building these training models by hand. He estimates that he created his first substation model in 1999, using components that he found at the hardware store. Cardboard tubes and spark plugs come together to form a miniature substation on which students can practice, with no danger of a deadly misstep.

When Patchen caught wind of the powers of 3D printing, its potential to be applied to his work was immediately apparent. “When 3D printing came into the picture, we thought, ‘Oh man, we could really make these models much more realistic.’” He also saw the opportunity to start reproducing models for other locations at a pace that just wasn’t feasible when he was building each one by hand.

“If I was gonna buy a printer, I wanted one with a big print platform,” Patchen recounts. Their size requirements are varied, he explains. Sometimes their prototyping needs are small-scale, but other times they want the ability to create large objects that would dwarf the average desktop printer. “We wanted…a single purchase that would best fit both those kinds of parameters,” he says.

He did his research and found re:3D. “The Gigabot was amazing because of its large platform and the ability to print small and large, no matter what our needs might be.” Patchen is now in the process of 3D modeling his original substation in CAD and printing out its 21st century cousin.

Patchen explains that the company recently invested in a state-of-the-art training facility, where he sees abundant opportunities to use their Gigabot for educational purposes. “Our goal as a utility is to be a leader in our industry,” he says. “In order for us to do that, we have to lead in safety, innovation, and technology. We believe that 3D printing is gonna help us get there.”

Tool creation from then to now

One challenge of the work is that, between different eras of design and the wide range of equipment manufacturers, a single type of equipment may have several different designs out in the field.

Because of this, there is not necessarily a one-size-fits-all tool for every job and every company. This can leave utilities to do their own tool creation when needed, to make the job safer and more efficient for workers and keep power flowing to their customers. Oftentimes, workers see areas for improvement, opportunities for a new tool that doesn’t exist that would make their jobs easier.

“When I first hired on, I was a high-voltage substation electrician. I worked in the field for many years,” explains Patchen. “If you had an idea for a tool that you wanted to create, you would have to draw it on a piece of paper or a napkin and bring it down to a local machine shop, and then they would do their best to build it.” That process, Patchen recounts, could take weeks to months – and that was just to get an initial prototype.

Anyone who’s been through the development of a product knows that the back and forth of the process – when not done in-house – can be quite costly in both time and capital. The first iteration comes back – often after a lengthy lead time – and design flaws become apparent. Revisions are made and submitted, and the process is repeated. More waiting, more money.

“Today with 3D printing, you can take your ideas and concepts and prove them out,” Patchen explains. “The average person can change the industry.”

3D printing cuts down on the tool design process in both the time and cost departments. A design can be printed and reworked on repeat until all the kinks are ironed out. “Then,” Patchen explains, “I could go spend the money at the mill or the machine shop, and it’s actually effective spending at that point.”

It goes without saying that this also slashes a massive amount of time from the process. They can internally turn around dozens of 3D printed iterations and settle on a final design in less time than a machine shop could get a first version back to them. “It’s a very cost-efficient way to change the industry using the field employees’ input.”

The challenges of tool development

Nowadays, Patchen’s tool creation process typically involves a manufacturer, so that when a design is finalized it can be mass-produced and made available on the market to any utility company who may also have a need for it.

There are several challenges that Patchen is confronted with when he’s approached with a tool idea from a field employee.

The first is the broad range of equipment designs that they’re making these tools to service. “In these substations, there’s stuff that was built in 1920, there’s stuff that was built last month,” he explains. This means that the same device with the same function can take different forms depending on what era it’s from. “When we have to build something, we want to make it fit all of those,” he says. “We want to be able to make one product, one time, and do it right.”

The second challenge is their partner in tool creation: the manufacturers. Patchen starts the process by approaching a manufacturer with a tool concept, they come back with an initial design, and the utility workers trial it out in the field. This, Patchen explains, can be tricky with manufacturers who aren’t in their line of work. “A lot of times, when the manufacturer’s trying to understand what your needs are, they’re not in the field, they don’t work in your environment,” he says. “They make tools, [but] they don’t understand how you’re using them.”

This can result in tools that are inconvenient or awkward to use and therefore difficult to actually put into practice, defeating the purpose of creating them in the first place.

With 3D printing, Patchen found a solution to this flaw in their design process. “When you get an end-user involved in creating prototypes, you’re really closing the gap on the amount of time and the cost it takes to create useful tools.”

Now, he and his team handle the early stages of the process, modeling CAD files and printing initial prototypes in-house. By the time they approach a manufacturer with a tool concept, they have a 3D printed prototype that’s already been put through the ringer out in the field. This allows them to leapfrog several steps ahead in the production process. “3D printing has enabled us to improve our innovation when it comes to creating new tools or specialized tools across a very diverse line of equipment,” he explains. “We’re able to come up with concepts, print the prototypes, and trial them out in the field, so when we communicate back to our manufacturer, the data is more accurate.”

Rather than discovering a design flaw after something has been expensively injection-molded, Patchen and his team can work out the kinks on their end and ensure the design they send to a manufacturer is accurate from the get-go. All that’s left to do at that point is create the tooling to mass produce it. Says Patchen, “It saves [the manufacturer] money, it saves us money in the long run, and lots and lots of time.”

At the 2019 ICUEE conference in Louisville, Kentucky – the largest utility and construction trade show in North America – four tools Patchen and his team helped design were on display. It’s a big honor at such a lauded industry event, but his focus remains on safety and sharing innovation so that other utilities across the nation can benefit. “I’m not trying to make money,” says Patchen. “I’m just trying to make it better for the employees in the field.”

Sparking industry innovation through new tool creation

Where taking a tool from concept to a purchasable physical product used to be a months- to years-long process, Patchen explains that 3D printing has given them the ability to slash that development time down into the weeks. “That’s huge when it comes to our type of work where we’re in such a high-voltage, dangerous environment.”

Much of the challenge and danger of the job stems from the simple fact that a utility company’s singular focus is keeping the lights on.

When equipment needs maintenance, they do what they can to keep the power flowing. This means that workers are almost always working near energized, high-voltage equipment – hence the necessity of Patchen’s job. And although there is always an inherent level of risk to a job which necessitates working in close proximity to high voltage, Patchen’s aim is to protect workers through the development of new tools, training, and work methods.

“Technology is changing our industry,” says Patchen. “Every six months, there is something new.” The blistering pace of innovation lifts the industry as a whole, but the challenge, Patchen explains, is staying on the forefront of that.

“We don’t want to sit back and just watch that happen. We want to be a leader in that,” he explains. “3D printing gives us the ability to be part of that process – to lead innovation.”

One ubiquitous tool used in the field is a live line stick, commonly known in the business as a hot stick. The lengthy, fiberglass poles allow utility workers to perform a variety of tasks on energized equipment, insulating them from the electricity and keeping them at a distance from machinery in the case of a malfunction or electrical arcing. The end of the stick operates as a mount for a variety of different accessories that serve a wide range of purposes, like pulling fuse and operating switches.

One hot stick variation that Patchen’s team uses is a switch lubricator. Workers were struggling to open sticky switches, often having to use a stick to forcibly hit at a switch five or six times. They remedied this with a hot stick that dispenses lubricant onto a switch so that it can be opened easily with one knock.

Part of the design is a control unit, mounted on the opposite end of the hot stick, with a button for the user to dispense the lubricant. The unit the manufacturer sent was large and clunky: a worker had to remove a hand from the stick in order to get to the button, sacrificing dexterity.

Patchen designed a new mount with a slim profile – probably a quarter of the size of the original unit – enabling the stick operator to keep both hands on the pole and simply move a thumb to hit the button. “We were able to use our 3D printer to create this new prototype that’s much more ergonomic and gives the end user more control when working in an energized, high-voltage environment.” Printed on their Gigabot and mounted to the pole with velcro straps, the new unit Patchen created is being adopted by the manufacturer as an option on new purchases.

Gigabot has opened a door for Patchen and his team, and the tool requests are streaming in.

There was the gas cap to attach a generator to an extended time fuel tank, out of stock when they desperately needed it during a widespread emergency and power outage. Patchen 3D printed it.

There was the camera mount hot stick used to inspect energized equipment that carried a price tag of nearly $500. Patchen printed it. Their 3D printed version of the mount attaches to other sticks they already have, at a grand total of $1.67 apiece.

The list goes on.

“We were recently approached by several field crews to create a special plastic cover that would protect them in high voltage environments,” Patchen says. There was no product on the market that fit the bill, so he got to work on a design with a manufacturer.

The equipment that needed to be covered took a wide range of forms in the field, complicating the product development process. Patchen gave the manufacturer drawings of the equipment and their product idea. Eight months later they still didn’t have a workable prototype.

Patchen stepped in. “I used my 3D printer, made a prototype, and got the product finished within three weeks. Now it’s actually purchasable on the market.”

But perhaps Patchen’s most impressive project of all is a small, unassuming plastic hook.

He and his team were confronted with a scenario in which they needed to perform maintenance on a 500 kV substation. “In our system, the highest voltage that we have – and one of our most critical circuits – is the 500 kV,” he explains. “To clear that equipment or take it out of service, we’d have to de-energize the whole grid, which can be quite costly – tens to hundreds of thousands of dollars.”

A teammate came to him with an idea to circumvent the clearance with the help of a specially-designed plastic barrier which would allow them to safely perform maintenance without shutting down the system.

The solution came in the form of a rectangular-shaped, high-voltage plastic cover, which would enclose each of the 13.8 kV circuits that connect to the main 500 kV bank. The covers would be mounted from below and secured in place with rubber rope and plastic hooks. The hooks that the manufacturer sent with the covers, however, posed a problem.

Maneuvering from the ground at the end of a 14 foot hot stick, a worker had to insert one end of the hook into the eyelet of the plastic cover in order to fasten it. Workers were finding the hook’s design difficult to navigate into place at such an angle.

Patchen took the feedback from the field employees, reworked the hook’s design, and printed out a new version on their Gigabot. The slight tweaks to the hook’s form were a game-changer. Where workers previously had to fight the old hook into the eyelet at an awkward angle, the new design naturally wants to snap into place.

“This small, plastic hook took about three hours to print, and it cost around five dollars.” Patchen can’t underscore its value enough. “We were able to take that [3D printed] hook and share it with other crews, and we avoided many, many 500 kV clearances because of it. This small, five dollar device saved us hundreds of thousands of dollars.”

He smiles and gestures towards their Gigabot. “That’s paid for the printer quite a few times.”

CES 2020: The Return of Gigabot X!

In October 2019, re:3D was honored to win the Startup of The Year competition at the SOTY Summit in Memphis, TN. The Startup of the Year team has been incredibly supportive since our win, and one of the great opportunities they provided us was to showcase Gigabot X, our 3D printer which prints with pellets, regrind and shredded plastic waste, last week at the Consumer Electronics Show (CES), in Las Vegas, NV.

You may remember the epic road trip that we took to get our team to CES last year (there were aliens involved!), and though this year we traveled in a slightly more conventional way, there were still plenty of laughs, mind-blowing tech and of course chats with new friends about #3DPrintingWithPurpose.

We exhibited in the 3D Printing row in Eureka Park at the Sands Expo, sandwiched between fellow 3D printing innovators, Plasmics and coffee gurus, Spinn. No, Spinn doesn’t 3D print their coffee, but it was, as the kids would say, dank!!

All week our booth was packed with visitors from around the world, initially drawn in by Gigabot X’s huge build volume and staying to learn more when we told them we were printing rockets with 100% Recycled PET pellets. Recycling and reusing plastics in 3D printers drew companies interested in sustainability, and we were thrilled to share that because of our partnership with Habitat for Humanity, our 3D printed chair was using 100% reclaimed materials: the rPET sides were supported by wooden slats made from unused scrap wood donated to the Habitat for Humanity ReStore.

The Startup of the Year trophy was our constant companion as we traipsed around Las Vegas, providing treats from its gilded cup to curious onlookers like some sort of bountiful cornucopia. Above, it graces our booth, an all-you-can-eat sushi restaurant, AFWERX Vegas and the Hackster.io party.

We joined an innovative group of technology startups to pitch at the NASA iTech Ignite the Night competition. co-Founder and Catalyst, Samantha Snabes shared our goals to put a Gigabot X in space as a means to recycle plastics into new tools for astronauts. We are thrilled for winner Otolith Labs who has created a wearable to reduce vertigo in astronauts. Many thanks to NASA iTech for the amazing opportunity which led to great conversations and potential collaborations to come!

3D Printing nerds that we are, we had a chance to check out what the rest of our industry friends were up to. Here’s a sample of gems from around CES:

Finally, some of us had the honor to volunteer as judges for the IEEE Entrepreneurship N3XT Stars Competition, which we won in 2018. From all the startups in Eureka Park, five finalists who most embody IEEE’s mission to foster technological innovation and excellence for the benefit of humanity were chosen and then narrowed down to three winners. Check out the new N3XT Stars: Longan Vision, Safeware, and Waverly Labs!

Thanks to all of our customers who stopped by for a high five and to all the new friends who helped spread our #3DPrintingWithPurpose mission throughout CES and beyond. Until next time, Vegas!
