Hello, Giga Friends! Happy summer from Texas! It’s been an amazing few months since we released Gigabot 4, Terabot 4 and GigabotX 2 at the start of the year. We’ve reconnected with many long-time Gigabot owners seeking upgrades, taking advantage of our free parts for older machines (don’t know about those? Get on our mailing list!) or purchasing new printers to add to their Gigabot family. We’ve also met many new owners doing fascinating projects with 3D printing as we continue to roll out our most advanced Gigabots, yet. 

The re:3D team has grown quite a bit, and on the engineering side, new teammates have taken on the task of putting fresh eyes on our parts and firmware to continue to iterate and improve our newest version, especially taking into account the feedback you have shared with us as beta testers and new owners. As such, we’re excited to share some updates with you on the progress of a few projects. As an open source company, we’re happy to report where we are in development of new tools and features for your 3D printers, stress testing and implementing them on Gigabot as they mature.

Touchscreen Case – Project Leads: Sami Hill and Alejandro Leal

With the release of the new versions of the 3D printers came the exciting addition of the full color, front mounted touchscreen, and it’s been a huge improvement for user interface over the previous VIKI controller. This is a work in progress update, and this case will be released as soon as it is fully tested. We’ve identified three main areas in which we’re iterating for an even better user experience:

  • Case Durability and Rigidity
  • Cable Connection to the Touchscreen
  • USB Drive Connection Point

Case Durability and Rigidity
We want this case to protect your touchscreen from bumps and falls as well as stay rigid when the touchscreen pivots on the mounting arm. As such we’ve thickened the case and bezel, putting more protective material around the sensitive electronic parts.

Cable Connection to the Touchscreen
Inside the thickened case, there is new cable routing to make sure cable bends don’t exceed their minimum bend radius, and we have added a cable sleeve at the entry point to minimize abrasion on the cables as the case moves.

USB Drive Connection Point
One of your common pieces of feedback is that the USB drive slot on the touchscreen is sometimes misaligned with the case. We’ve added internal bracing to that slot so the cable stays put and cleanly receives USB drives to load files onto the 3D printer.

Simplify3D v5 – Project Lead: Jordan Smith

The release of Simplify3D v5, our preferred slicing software, came with some great new features we’ve been testing on Gigabot. We’ve been most especially excited by the new infill and support patterns allowing quicker, cleaner support removal and morphing infill for stronger internal structures and better top layer finishes. Simplify3D v5 also added support for Klipper commands, which we’re excited to explore. Alongside the new software release we now have fully tested Simplify3D v5 FFF profiles available for your Gigabot 4 3D printers.

Klipper Software – Project Lead: Mitchell Mashburn

We have been diligently progressing on a new software update, v0.4.0 for Klipper stack, expected to be released soon. This update, based on your feedback, aims to offer a more optimized and up-to-date software experience for Gigabot owners. As part of this update, we have upgraded various components, including the Klipper firmware, Moonraker API, and Mainsail front-end interface. Detailed changelogs for each component are available via the links below.
While we conduct further testing before the release, we invite Gigabot owners running Klipper to participate in our alpha/beta testing program and gain early access to software to help us identify issues (apply here:

New Year, New Printers! Meet Gigabot 4, Terabot 4, GigabotX 2 & TerabotX 2

A green plated circuit board with many electrical components.
Left To Right: Gigabot 4 with Enclosure, Gigabot 4 XLT, Terabot 4, Exabot, TerabotX 2, GigabotX 2 XLT, GigabotX 2 with Enclosure

Introducing the Next Evolution of re:3D 3D Printers Featuring Klipper Firmware and ArchiMajor Control Boards

When deciding what changes to make on the next version of your Gigabot and Terabot 3D printers, your needs came first. The Gigabot family of customers has always inspired us to push this technology forward because it’s what you do with it that motivates us. Whether you’re teaching the next generation of change makers or innovating in advanced manufacturing, your feedback determines where we put our R&D focus.

The biggest visual change you’ll see on all versions of re:3D 3D printers is the front mounted 10” full color LCD touchscreen. The touchscreen includes temperature, and motion controls, temperature history graph and preset macros. The menu options add file management, gcode editing, command line input, and print history analytics and tracking. Also included is a webcam viewer for remote monitoring and an integrated USB port for loading gcode files directly on to your printer.

This touchscreen software is just one component of our new Klipper open-source software stack. We’ve transitioned from Marlin firmware to Klipper because it enables high precision stepper movement, smooth pressure advance and input shaping, and also an API server that enables opportunity for custom development. The Klipper web application runs the touchscreen from a Raspberry Pi and enables you to access the printer from your local network on desktop or mobile browsers with all the same control options you’re able to perform directly at the printer.

In order to successfully integrate this exciting new software stack, we’ve overhauled our electrical system starting with the control board. We partnered with US based manufacturer Ultimachine to design a custom 32bit ArchiMajor control board for your Gigabot. The advanced board features eight integrated stepper motor drivers, three heater outputs, five thermocouple inputs, four controllable fans and eight endstops. These provide flexibility to extend the functionality of your Gigabot, for example, adding an additional thermocouple or part cooling which is under development at re:3D. The new control board and the Raspberry Pi are now inside a 16” electrical enclosure with an integrated power switch, power filter and more durable flex rated cabling. Not only does this board increase your 3D printer’s processing power, but it allows us to better control our supply chain and electronics quality with a strong US manufacturer as our partner.

View the press release about this partnership.

Platform-Wide Features

Stress tested in the re:3D factory, the new tube-style thermocouple is a more durable, consistent and accurate temperature reader for your Gigabot. We’ve added this improvement with a ½” thick aluminum bed plate, that is precision-blanchard ground flat and parallel to less than 0.005”. The bed is heated by a full-size silicone rubber heating pad, which allows the printing of high-temperature industrial materials. A robust cable carrier and cables rated for 1 million cycles of flexing protects all moving wires. Additionally, all unenclosed printers come standard with full side panels to protect electronics and cabling

FFF Filament 3D Printer Features

In the transition from Gigabot 3+ to Gigabot 4 we’ve pushed out some changes early as technology improvements have increased reliability and longevity for your printer. Many of these updates center around the extrusion system: The all metal extruder body, 20 Series Hot Ends for 0.8 nozzles and Terabot 4, tube style thermocouples and heater cartridges are all standard, combining to make the most robust, industrial extruder system ever on your Gigabot.

To keep Gigabot affordable you may still purchase a regular 600 mm cubed Gigabot 4 as a kit which ships in flatpack boxes, and the full enclosure is an optional add-on for pre-built Gigabot 4 and Gigabot 4 XLT sized 3D printers. Terabot 4, as before, comes with the enclosure standard. One change we’ve integrated as standard is the side panels on your Gigabot cover the full side on the left and right to provide better protection for the motors and electronic components.

As with the changes we made during Gigabot 3+’s lifespan, This is just the beginning. Gigabot 4 will continue to iterate and grow and change to meet your needs as the technology evolves. Plans are already in the works for a filament dry box, bed probing and even more robust build plate and frame improvements. Stay tuned!

FGF Pellet and Granule 3D Printer Features

Since releasing the beta version of Gigabot X in 2018, re:3D invested significant R&D resources from community support to produce a more agile, advanced and capable fused granular fabrication 3D printer.

GigabotX 2 features a feeding and extrusion system precision engineered for processing pelletized and granular thermoplastics. Material is manually fed into the 24 hour capacity hopper which rides on an independent hopper gantry system, to allow a full and smooth range of motion and consistent feeding into the extruder.

Print material flows from the hopper into the extruder via either the gravity fed feed throat or the optional active feeding system, or crammer, which includes a motorized auger that pushes material into the extruder with a user controllable feed rate.

The GigabotX 2 extruder is powered by a 425 ozf*in NEMA 23 motor with planetary gear box to provide increased torque for flowing materials. The extruder is a solid steel ⅝” screw with 16:1 L/D ratio designed with our partners specifically for consistent throughput for thermoplastics. Three independently controllable heaters are mounted on the extruder barrel allowing for extrusion temperatures up to 270°C. Interchangeable nozzles between 0.4mm and 2.85mm in diameter can be used to control resolution and extrusion width.

GigabotX 2 is the culmination of our mission to enable more users to 3D print directly from novel and waste plastics, but we’re not stopping here. Research is currently underway to integrate a granulator, dryer and automatic feeding system with GigabotX 2 to make machine operation even more efficient and user friendly and enable anyone anywhere any time to be the problem solvers for their community.

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.

" 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!)

Not in Ohio like Pamton 3D? re:3D Design and Contract printing services ship worldwide, and we’re always available to provide you 3D printers, 3D prints or 3D models to meet your needs.

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.

Supski Paddle System by Guy Chaifetz

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.

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.

Gigabot 3+ 3D Printing AMCPR Couplings

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.
