Diameter : – 2.86mm

Color Tested: Slightly green/brownish

Date Tested: 2/28/2016

IMG_2133

OBSERVATIONS

Ease of use: A little tricky due to the brittle nature of the filament, however, once you get started you are good to go!

Appearance: Aesthetic, reflects sustainability, “rough texture”, definitely not smooth!

Size consistency:  Average, within .1mm within roll.

Color consistency: Great, consistent throughout roll.

IMG_2134

SETTINGS

Print temperature: 175 C (nozzle) /55C (bed)

Printer Used: Gigabot

Speed: 30mm/s

Layer Height: 0.3mm

Infill: 35%

Odor: Earthy, smells like algae

Type(s) of print surface used: Print n Z

List of test files printed: re:3D’s test files 1, 2, and 3 (logo, vase, airplane gear piece)

 You can watch a video  summarizing our testing:

FINDINGS

Bed adhesion (1:terrible-5:fabulous!)

  • 4 (could have been optimized by adjusting cooling/ temperature)

Stringing (1: lots -5: none!)

  • 4 (could have been optimized by adjusting speed/ temperature)
    • Only noticed slight stringing in vase

Shrinkage (1:lots-5: none!)

  • 5-None!

interlayer adhesion (1:terrible-5:fabulous!)

  • 5- Perfect!
IMG_2155

NOTES:

  • A renewable filament that reduces the environmental footprint of production is highly appealing to the 3D printing community.
  • The biggest limitation is the brittle nature of the filament, making initial setup a little tricky. NOTE: this filament was tested 4 months after receipt, however, for many users a 4 month shelf life is ideal.
  • Filament size consistency was about on par with most filament.
  • Little delamination and no curling was observed.
  • All testing was conducted at the lowest temperature and speed range that the manufacture provided. It’s likely that the outcome would have been even better had the mid to high range temperature ranges had been explored.
  • The unboxing experience was well done and the recommendation sheet was professional.
  • We appreciated the made in America reference, and date stamp of quality control on the box and insert.
  • Manufacturer recommended settings were easily referenced on the enclosed insert

RECCOMENDATIONS:

Not all users may appreciate the aroma, however if you are looking for a more sustainable 3D printing alternative and doesn’t require a smooth surface, this materials may be for you!

2016: Stories Made in America

Over the past 3 years our company and community have seen a ton of changes. Through a shared vision to make industrial 3D printing more accessible, our team rallied from multiple locations across the US, scaled our idea in Chile, and later established headquarters in Texas. Since launching in Santiago, we’ve opened two offices in Houston & Austin, which is complemented by a remote sales presence in San Francisco.  Although our team is centralizing operations in the USA, re:3D remains thankful to our Chilean roots and the $40K in funding that gave us the opportunity to make an idea a reality.

We also recognize that through our 2 crowdfunding campaigns that Gigabot’s reach has expanded to new frontiers around the world.  We will always attribute our 2013 Kickstarter success to the thoughtful insight, organization, and advertising enabled through the Start-Up Chile program. However, since leaving Santiago after 7 months, customers and suppliers throughout both North America & South America have emerged in Texas and beyond.

IMG_0818
Visiting Mkerstudio MX / Impresión 3D Gigabot & team in Mexico City

With this in mind, we’ve invested considerable effort into analyzing how our community and resources have evolved over three years. For example, you can view a breakdown of where our customers are located in the map on our website. In our examination of where re:3D has impact, we’ve discovered that over 80% of the materials we source for Gigabot, 100% of our labor, and 78% of Gigabots in the field are in North or South America.

In 2014 & 2015 we also sent out surveys to our community, interviewed over 50 customers in person and attended events throughout the US that allowed us to engage with up to 500,000 people to hear your thoughts on human-scale 3D printing. Undeniably the biggest request of all of our road-trips was that we share stories of our personal adventures printing huge and those of the 300+ Gigabots worldwide. We’ve also had a strong demand for a more robust forum, which Mike is hoping to launch next month- more to come!

As we’re still proudly bootstrapping, it struck us that we have an enormous opportunity to immediately leverage the dense community around us to photograph, video, and document the customers we encounter. We’ve devised a list of questions to capture information we’re told you want to hear:

  • Longest print
  • Biggest print
  • Application/ reason for printing huge
  • Materials tested
  • Favorite print
  • Challenges, feedback and requests
  • Cost and Time Savings
  • Your Gigabot Workspace
  • Your workflow

We hope this is only the beginning of building stronger relationships with all of our customers personally. We aspire to eventually meet all our customers, and are focusing first on sharing the stories of those closest to our operations first. We’re hoping to socially engineer affordable ways to ultimately canvas the globe, but for the short term we’d like to intentionally focus locally.

route66

With this in mind, we’re pleased to announce our Made in America campaign. Each week, beginning next week, you can anticipate a blog, video and photographs that share the experiences of pioneers like you, who #dreambigprinthuge as we hit the road to engage with our American clientele.

To ensure we are fulfilling your requests for more curated content, we’d love your input. What questions would you like us to ask customers? Who would you like us to visit? Are there any National Parks we should check out enroute? We welcome your suggestions at marketing@re3d.org as we embark on an adventure to explore what’s being #madeinamerica on Gigabot.

Happy Printing!

re: 3D Printing Furniture

My first attempt at 3d printing furniture went pretty well. The stool I designed  and later printed on the Gigabot ended up on-stage with Samantha Snabes, Co-Founder of re:3D, presenting to 5,000+ attendees at Web Summit in Ireland. Somehow along the way, Prime Minister Enda Kenny struck a pose with it. What an honor!

re:3D won 2nd place out of the Beta Pitch group and the 3D printed stool made it into several of the pictures that ensued; very exciting to watch the twitter streams.

For my next project, the goal was to create a piece that combined 3d printing with existing materials. I had been saving a slab of walnut purchased from eBay and thought, why not turn it into a bench? It was a pleasant challenge designing the base to follow the feel and flow of the live-edge slab. I wanted technology and nature to seemingly merge. It’s a beautiful slab and I needed to do it justice! There’s a great book out there about how loads are distributed in nature which helped to inspire the bench; it’s called “Design in Nature: Learning from Trees” by Claus Mattheck.

benchinprocess

The piece required a two-part print due to the large size so it was split it at an inconspicuous angle down the middle. The base was designed with pocket-screw holes and once lined up, was secured to the live-edge slab with pocket-screws. While the print itself was structurally sound, I coated the entire bench in clear epoxy just for some added strength. The gloss finish on the base was sanded back down to satin using 200 grit sandpaper. The indicators on the bench represented spots that I had missed with epoxy; they pointed out where I had to touch up on a second coat.

I was very pleased with the result and honored to have been included in Big Medium’s Austin East alongside many other great artworks.  Even Google’s self driving car stopped by to see what’s up. I think they look good together.

Mike’s 3D printed bench is featured at the Big Medium East Austin Studio Tour (self-driving car for scale:)

Having access to a Gigabot has opened up so many more doors due to it’s scale and precision. Can’t wait to start my next project which I will be sure to post about in the next couple of months.

Happy Printing!

re: thinking Buoyancy – Hanging 10 on a 4pc PLA Surfboard

The Big Idea

Like most start-ups intent on exploring the intersection of tech and sheer awesomeness, the vision to 3D print a surfboard was cast over beer, at a co-working space (Capital Factory), subsequent to a lack of sleep. Disregard the fact the nobody physically present at our Q2 re:treat had actually surfed, we were still proudly penny-pinching, and had few Gigabots available for extended personal print marathons. Instead, Marketing Co-Leads Katy and I corroborated with our Gigabot Ambassadors Rebecca, Morgan and Todd to develop a list of “use cases” to demonstrate functional 3D printing to be executed by a cadre of summer interns. Buoyancy made the shortlist, and a surfboard was an obvious case study.

IMG_0446
Q2 re:treat with @Marvin_3D

Our leadership team cultivated job descriptions, which Katy hosted under a tab she designed at re3d.org/careers. The response to our unpaid internship postings were higher than anticipated, and ultimately we selected Akshay as our 2015 Design Intern focused on 3D Printing a surfboard. Despite still being in High School, his confidence, professionalism and experience modeling through his high school FIRST Robotics team convinced me he was up for the challenge. He also had a glowing recommendation from his coach Norman.

IMG_0574
Brainstorming over Amy's Ice Cream w/Matthew, Annabelle & Akshay

The Design

Within just a couple weeks of on-boarding and conducting research on surfboard 3D printing, Akshay presented his concept. He had identified others who had been successful including a Father & Son, as well as professional 3D printed surfboard companies. Those that have gone before had done an amazing job curating surfboard designs that truly exhibit the benefits of 3D printing, whether it be enabling custom designs or geometries not easily produced in traditional manufacturing. However, due to the small volume of many affordable printers, we noticed multiple parts were required to later be stitched together like a jigsaw puzzle or they depended on expensive SLS printers to produce a monocoque body.

Endless Sinter SLS Surfboards

ABS Jigsaw Surfboard

Knowing that we had the benefit of leveraging one of the largest affordable industrial printers at our disposal, we set out with Akshay to investigate if we could make a FFF (Fused Filament Fabrication) design in the fewest pieces possible. We also wanted to challenge notions of material strength. Akshay’ s research unveiled that our desktop 3D printing peers used ABS, a plastic despised by many for its stinky smell during printing, but stronger than it’s as readily accessible counterpart PLA. Being bootstrapped, we work from a small office, so we decided to use PLA to print our board to see if the sweet smelling, accessible filament could support the weight of a human in the ocean repeatedly, thus challenging the assumptions of PLA’s limited value in functional, life-sized 3D prints. You see, we didn’t choose PLA because we thought it SHOULD be the material of choice, rather we wondered if it  COULD be used in a functional application.

And if it worked (even limitedly), we wondered…..what other applications would you and other members of the open-source community cultivate that could expand on our buoyancy experiment?

IMG_0994
Akshay dialed into Katy's Design Tag

To develop the initial concept, Akshay paired up with our Summer Stand-up Paddleboard Design Intern Evan, who was also exploring the possibility of supporting a load on water.  During Katy’s Thursday Design meetings they evaluated each other’s models in Solidworks, discussed stress points, and analyzed the best way to join components. They also ran a series of experiments to deduce not only if PLA floated, but also if it could be water tight. While they initially pursued similar concepts involving a series of rods conjoining dense pieces, they later opted for separate methods. The stand-up paddleboard included a series of hollow segments, filled with Great Stuff, bound with Gorilla Glue, and fiber wrapped.  The surfboard, Akshay decided, would be four, 6% honeycomb-filled segments held together by a series of 50% infill 3D printed bricks. Like Evan, his instrument of choice for sealant included copious amounts of Gorilla Glue.

This was our first foray into a “formalized” summer intern program and the weeks flew by. We learned a ton about setting deadlines, procurement delays, accounting for R&D or marketing inventory in our budgeting & bookkeeping, and how to better mitigate bottlenecks in Gigabot availability for multiple, multi-day crazy prints.

As June turned to July, the scaled-models and sketches transformed to full-scale experiments. Katy’s design meetings became increasingly important as the group collected feedback from the team and data from real-world tests which influenced model adjustments.

Fin Design

Throughout the summer, the surfboard fin underwent as significant an evolution as our scaling team using input from experts, the open source community, and our own failures. Askhay’s first design included two tabs to be glued into the frame, which floated and appeared to have the infill & form required to be successful based on our initial tests. However, after delving into the minutia of surfboard design, Akshay discovered that most fins are supported via a T-slot in the surfboard body. For this reason, he later designed a fin to be inserted into a groove. Unfortunately, we later learned we needed screws holes on either side to mount into the T- nuts. Mike responded to the challenge and mocked the final design, which included the re:3D logo as well as fixtures for the screws to mount into Akshay’s conceived T-nut slot. Mike also suggested that the fin be printed in black to complement Akshay’s silver board.

Final Construction

By the time the 1.5 long week print was ready for the final piece, July had morphed into August and Akshay had to return to high school.  A couple of weeks into September we attempted to resume the project and he modeled the 4th piece using feedback I relayed remotely. Despite my best efforts, the measurements provided were a little off and the 4th piece wouldn’t align. Both Jeric and Mike supported a redesign and during a long weekend, Mike ultimately generated the final component to Akshay’s vision as well as some much needed “deckholes” our research revealed was required for a surfboard leash, which we purchased from SUP ATX as we figured the extra length on stand-up paddleboard leashes offered might be needed later. With the body complete, we encountered a new set of challenges. During a commute between our Houston and Austin offices, our almost finished 3d printed surfboard took a tumble on our high-strength 3D printed bicycle designed by Patrick, leaving a rather impressive hole. Determined to make it work, I filled the  crevice with silicon prior to using Bondo to level the uneven Gorilla Glue texture.

Jeric did a stellar job capturing a time-lapse of the final piece!

The Test

While touring an untested BETA experiment 7000 miles might sound crazy, for our team it made perfect sense. We had won 2nd place at Websummit last year for pitching our vision to 3D print from trash and 1st at their US event, Collision which granted us free passes for our team to return to Ireland. It therefore seemed natural to transport a untested ambitious print across the sea in front of thousands of media & startups in the name of challenging assumptions around 3D printing.  Upon reflection on the flight to Ireland, it became evident that our success to date and win at Collision, was truly a testament to community support. For this reason, we decided it would be an honor to recruit as many stickers as possible from Web Summit attendees willing to affix their brand to our untested experiment. We humbly collected 150+ logos, including StickerMule, a popular vendor.

Shaun the Sheep

If you followed us or Web Summit/Surf Summit on social media in the past month, you might be a little confused by the multiple references to sheep, Shaun, Gigabot, Irish shepherdesses, and surfing sheep.

The idea to 3D Print Shaun the Sheep was conceived by a female Sheppard & blanket maker named Suzanna of Zwartbles Ireland. Suzanna maintains an active community via social media (@ZwartblesIE) and during our flight over suggested #Gigabot could #3dprint a #sheep in #ireland. The initial Tweet inspired a lively conversation and I found myself Googling open-source sheep stls while flying past Iceland. When Katy & I landed, Matthew suggested this Wooly Sheep by pmoews  to test out on Gigabot, which had been created using a 123D Catch, now ReCap Pro, scan of a garden ornament. Three days of continuous sheep printing and ewe puns soon began. Katy christened the first small-scale sheep as Dolly before making a larger 14 hour sheep. The downside of running large prints is that Gigabot has to work throughout the night. The 3rd shift security team had the pleasure of watching our biggest sheep complete and informed us one morning that they had named him Shaun. It wasn’t until later the next day that we learned Shaun referred to a popular show titled Shaun the Sheep. Shaun quickly garnered a small fan club, and we decided to take him to Sligo, Ireland for Surf Summit as the prize for the 1st surfer to successfully catch a wave on the surfboard.

Surf Summit: The Moment of Truth

As soon as Web Summit concluded, we crated Gigabot for the return to Texas, them scrambled to pack our bags, the surfboard, and sheep for the bus ride to Sligo, the host of Surf Summit. Surf Summit is an incredible post-summit event to cultivate friendships while experiencing the Irish countryside. As the video reveals, it was a breathtaking experience- our only regret being Matthew couldn’t attend in leu of a customer he committed to visiting in the UK. As complete surf novices, Surf Summit provided the perfect proving group for the surfboard test as several surf pros were in attendance to share their experience & wet suits!

IMG_1139
Shaun, Katy, the surfboard & I board the bus

Prior to surfing, we attended the kickoff festivities and allowed Shaun to circulate with the attendees before (he hoped) he would be gifted to a deserving surfer.

Session 1

The next morning we loaded the board, attached the fin, crossed our fingers for good luck and took off to Streedagh Beach. Upon arrival, we were greeted by a team of instructors from Surf World Bundoran, who helped us wax the board and taught birthday girl Katy & I to surf for our first time. The experience was unforgettable.

As our lesson concluded, SurfWorld Instructor Tony volunteered to take our stickered print out on the water. We grabbed our cameras and huddled with our new start-up friends from The Outdoor Journal to capture a mini photo shoot before take-off. The tension was palpable and we all lingered a moment discussing the project, for fear that the board was soon break or worse, sink, taking with it the evidence of so many peers who had supported the endeavor.

Tony proceeded with caution, first testing the buoyancy in shallow waters near the beach, then gradually paddling out further. After a few minutes, he headed out to see if he could catch a break. It wasn’t long before a series of rolling waves emerged and, as luck would have it, he was able to ride one in!

After Tony broke the seal, two other brave instructors also offered to take the surfboard out, despite loosing a fin!

Session 2

Wanting to optimize our wave catching, we headed back to the hotel, then caught a cab to Strandhill beach to join another surf instruction course after lunch. There we met the crew at iSurfIreland who agreed to try her out and broke personal records in distance traveled (which complicated picture taking)! Four surfers tested the board, and gave us valuable improvement ideas.

Feedback

In total 7 instructors braved the board. The advice we received was pretty consistent:

  • The current board is too thick
    • In the future it should be thinner and consideration should be given to reducing weight
  • The curve is not ideal
    • The board should bow more at the top
  • We could have better leveraged the benefit of 3D printing
    • The current design mirrors current manufacturing aesthetics and could have been sexier
    • Surfers appreciate custom features (holds for cameras, grips, personalized lettering)
  • The absence of a durable fin made it hard to maneuver
    • I should have printed the fin flat so it couldn’t delaminate, and/or used honeycomb for more density
  • A three or multiple fin design would be ideal
    • Ours had only a single fin
  • Stickers made the board more slick, albeit cool!
  • Everyone seems optimistic that 3D printed has great potential in watersports, especially wakeboards and body boards

One Month Later

Currently the surfboard resides in our Austin office. What began as an idea, transformed into a internship, that took us 7000mi and introduced us to new friends around the world. As we reflect on the people we met through Akshay, sheep printing, sticker collecting, and trial by water we are struck by the creativity & vision that the community shared. We hope this is the first of many use cases that will expand our perspective on what is possible through affordable, life – size 3D printing. We welcome your ideas on where we go from here!

Happy Printing,

My Great Big Gigabot Summer at re:3D

While applying for summer internships last spring, I did not imagine I would be as involved or as integrated into the company team as I was during my time at re:3D. This past summer, I got to explore and expand upon some of my own passions while taking on the role as the project lead for re:3D’s Great Big Gigabot Giveaway.

As I read the job description for film/social media intern position, I was excited that I would be able further explore my interest in creating videos. This is exactly what I did! This summer I worked with a video editing software called Adobe Premiere Pro CC for re:3D. Having prior experience with only Apple’s iMovie and Windows Movie Maker, I was eager to learn a more versatile software. My role as a summer intern soon evolved to specifically revolve around the second giveaway competition. re:3D was approaching the milestone of shipping out its 300th Gigabot, and the tradition of celebrating such a memorable moment is to give back to the community by giving away one of their industrial 3D printers to some with a vision to make a difference through 3D printing. You watch this year’s announcement video that I developed to announce the contest here.

I had the opportunity to work closely with Samantha and so many other amazing individuals through helping organize this competition. We recruited several amazing judges and in-kind sponsors, and I was astounded by the amount of support we got to help make this project possible. Even members of Tunapanda, the recipient of last year’s giveaway Gigabot, were happy to judge and sponsor this year’s competition. Check out all of this year’s judges and sponsors here if you haven’t already!

Pre-planning the competition with Jones Dilworth
Pre-planning the competition with JDI

Out of all the things I experienced during my summer at re:3D, my favorite was probably being one of the first to see the applicant submissions for the competition. Even though the applicants were very diverse in their backgrounds and ideas, I realized that they all had one key aspect in common: the passion to positively influence their communities. One thing I wish I could go back and change about the competition structure is the length of the submission period. We had several people with great ideas start their applications, but not as many people complete them. It was awesome to see all the people who put forth the effort to create a video to enter into the contest.  We also were honored to see the story posted on several industry blogs: 3Dprinting Industry, 3Dprint.com, and Techfortrade.

The purpose of the Great Big Gigabot Giveaway was to give back to the community by supporting an idea to impact society, and well, the 3D printing community certainly has a far reach. The recipient of the 300th Gigabot is Tochukwu, the man who is behind 3D Nigeria. This project plans to inspire a new generation of makers in tertiary institutions in Nigeria. Tochukwu and his team of makers hope to unleash the creative potential of these individuals and create value for consumers.

A big congratulations again to the winner and the runners up, Ability Maker and The Creator Program. You can view the incredible ideas of the entrants in the winner announcement video here or below:

All-in-all, I learned a lot this summer at re:3D from being directly involved on a project I could call my own. More importantly, however, I can definitely say that the best take-away was meeting such extraordinary people and cultivating those relationships. Looking forward to working on another project with re:3D in the future!

How I 3D Printed RWBY’s Crescent Rose

For a long time, my best friend Mason has been bugging me to watch Rooster Teeth’s animated show RWBY. Don’t get me wrong, I love anime, but I was already watching too many shows, and kept putting it off. Then, one day, re:3D’s cosplay enthusiast Rebecca asked if there was some way we could print the Crescent Rose (the instantly recognizable, 6ft tall scythe from RWBY). I immediately said yes, which made me finally binge-watch volumes 1 and 2 of RWBY on Netflix. Much to Mason’s delight, I loved it! I was super excited to make the scythe, not just because of my inner fangirl, but for the creative challenge of creating a 6 foot tall 3 foot wide scythe!
Rebecca and I debated for many hours about how to go about the design for the scythe. As you all might know, the Crescent Rose has the ability to transform into a more compact gun. We discussed the viability of this option ,and ultimately decided that because of the plastic we would be using and the laws of physics, that we should pursue making the best possible scythe-version of the Crescent Rose, and not worry about it transforming.

So, I threw myself into research. I spent many hours pausing the show and sketching, as well as staring at various other interpretations of the scythe on google images. I finally decided on a plan of action, and started modeling the scythe in Onshape, a beta CAD software.

When using a 3d printer, it’s important to keep in mind how your piece is going to be printed. 3D printers start to print from a base layer up, and use supports for overhanging parts. Therefore, I modeled most of the scythe to be easily printed from a flat bottom. Although I could have modeled the piece completely true to the show, I gave up some minor design features so that my prints would be faster and use as little supports as needed. The Gigabot, because of its large print size of 8 cubic feet, allowed me to make the individual pieces much larger and easily create a life sized model of the scythe.

I made the model into 11 different pieces that could be assembled after they were pulled off the printer. I then printed these pieces using PLA on a Gigabot. I used different infills and layers for different pieces, 2-3 layers depending on how much strength I was going to need from that piece and ranged 5-20% infill depending on if I need the piece to be light or not. I usually heat the plastic at around 195-200 degrees Fahrenheit.

When assembling plastic pieces, together keep in mind in order in which you want to paint your piece, and the different bond strength of the glues or tapes you are using. For the Crescent Rose, I mainly used just basic Gorilla Glue super glue. For more stress intensive pieces, I used Gorilla Glue epoxy and clear caulk to give joints a more uniform look.  

After we had finished printing all the pieces, the next step was to remove all the support material. Then, I sanded down and fixed the smaller print errors such as place where there is a slight over-extrusion on corners or small print-shifts. Finally, I started painting! A timelapse of the process is available below.

I used a basic white primer spray paint that sticks to plastic. This created a good base layer on the models that I could paint other layers of spray paints and acrylic on top of. For the majority of the scythe, I used red and chrome spray paints and then used black and red acrylics and a paint brush to finish detailing.

My Crescent Rose actually ended up being a little too big, finishing at 6’10” tall and 4’4” wide. I had the outstanding luck to get to bring my scythe to the Rooster Teeth offices and, who should happen to walk by but the voice of Ruby, the very character who wields the Crescent Rose– Lindsey Jones!

Everything was not all roses and sunshine though. I had some large problems throughout the course of making this scythe. Some pieces ended up being more fragile than I would have wanted, and broke a few times. The overall size and shape of the scythe creates its own unique problem. Even though the material is fairly lightweight, the scythe acts as a natural lever where the fulcrum is where the staff meets the blade, causing a large amount of pressure and tension right at the joint. My solution to this problem was more gorilla glue and wooden and metal rods drilled into the plastic and hammered through to help support the weight.

Another huge problem that occurred during the print of one of the pieces completely failed on us. The head of the Gigabot extruder got clogged 48 hours into the 55 hour print. Fortunately, when a print fails, the print usually has a flat layer at the point of failure. I was able to measure the print, and edit my model accordingly so, so I could print only what was missing. The end result looks just like a filament swap mid-print. I credit the ease of this fix to the great usability of OnShape.

Finally, the last and probably worst problem I ran into was the Texas Summer Sun… This is a problem that is unique to people in the south who use 3D printers. Even though the plastic melts at roughly 200 degrees fahrenheit, your print will warp if left in your car or your backyard too long. This happened on the largest piece of the scythe and caused my really nice print fix to be extremely noticeable. I had to reheat my piece and to try and warp it back to a usable condition– with limited success. I decided at the end that the condition of the piece after I re-warped it was good enough to merit not reprinting 55 hours worth of plastic.

In order to save you some work modeling, I posted the files on Onshape so that you can print RWBY’s Crescent Rose too!

I’m unveiling the files at RTX at the re:3D booth prior to our Panel today (Aug 8th) on 3D printing & cosplay. You can check out the panel at 1pm at the JW Marriott, Room 303.

You can find me on twitter @jacobelehmann to discuss the process in more detail.

Crazy 3D Prints: Making a Ping Pong Paddle

What do 3D printing, a table tennis, Gigabot and PETT have in common?

An amazing use case for custom, functional outdoor prints!

Until recently, printing large objects on FDM 3D printers was limited to small scale objects subjected only to controlled, room temperature environments. However, with the introduction of high strength materials like those offered by 3D printing filament expert taulman3D, making functional objects that can weather the Texas heat is now a possibility.

Enter t-glase. This material prints like Bridge Nylon, but with almost no shrinkage. You can learn more about the main features of t-glase on the taulman3D website. We heard about t-glase during a call with Tom Taulman when we shared a need of another local start-up seeking to 3D print custom table tennis paddles. Originally they attempted to 3D print their original design at the University of Texas. After several failed attempts to fit a set of paddle parts on a desktop printer, a local professor suggested they speak with us. In our conversation, we learned a lot about table tennis and the amazing potential 3D can offer those looking to customize paddles!
 
Uberpong™ makes custom ping pong paddles by blending art and design with the sport in a revolutionary approach that goes beyond the game itself. Uberpong also introduced us to Pongtopia, an app to find ping pong tables around the world. As you can see on Pongtopia, table tennis is played both inside & outside, suggesting that in addition to needed a high strength material with a little give, we also needed to source a material that wouldn’t warp or crack in heat or cold playable weather conditions. This would be similar if we were printing a regular sized tennis racket that would be used by a tennis coach for beginners sessions for example, so it’s good to bear in mind the material that needs to be used must be hard wearing.
 
In support of the experiment to see if ping pong paddles could be successfully printed on Gigabot, Tom shared some red t-glase samples. We printed Uberpong’s original ping pong paddle 3D design at our Houston office on Gigabot live during our June Open House with Hubs. It was an awesome opportunity to have 3D printing veterans weigh in on the outcome & settings.
 
The experience was hugely educational. As seen on the paddle on the left, I originally forgot to use a glue stick on the print surface to increase adhesion. Also, initially I printed a little too low at 225 degrees Celsius. After getting some guidance from the t-glase webpage, I increased the temperature to 235 degrees Celsius which resulted in a better finish. Using 235 degrees Celsius and a glue stick, the second paddle turned out great. Unlike the paddle on the left, which has a slightly rough temperature until I increased the temp and curling from the lack of a glue stick, the right was firm, glossy and completely flat.
 
With the paddles complete I drove them to our Austin office, which is nestled downtown near Pongtopia. We agreed that the next step would be to find a proper table tennis facility to test the prints. Using their app, we discovered Easy Tiger, a casual hot spot with multiple tables set up on their patio. Prior to meeting up, I took the initiative to glue the handles together with Gorilla Glue, and press them in a vice overnight. While the adhesive was plenty strong, I neglected to consider the foam that Gorilla Glue inspires, so as you will see in the videos below, the paddles were a little less aesthetic than they could have been with clear superglue!

After playing a match and drinking a couple of pints of cider at Easy Tiger in Austin, Rebecca and Dave shared their musings on the paddle performance and applicability for 3D printing in table tennis.

Overall, despite my adhesion and profile hiccups, we give taulman3D’s t-glase two thumbs up! We’ve even decided to resell t-glase on our shopping site! The ping pong paddles were firm, but offered a slight give. Despite the 100 degree Farhenheight Texas heat, we weren’t worried about the paddles deforming in the rays. This new material gives table tennis players worldwide a unique opportunity to customize their paddles. We can’t wait to follow Pongtopia and see how 3D printing and this industry evolves!

3D Printing Musical Instruments: The Ukulele

Pranathi Peri is developing a set of 3D printed, playable musical instruments for her summer internship. In her own words, she describes her design process:

Have you ever wanted to 3D print your own ukulele? Well now uke can! For the second instrument of my 3D printing internship, I decided to design and print a ukulele. After all, who didn’t trawl the internet looking for the best acoustic guitars under 300, and then end up with a ukele anyway because it was cheaper? They have such a charming aesthetic, and it’s that student living nostalgia that I wanted to try and tap back into. It also dramatically simplifies the process of choosing an acoustic guitar for your child, you can just print one instead now. Although, we have to admit, perhaps it won’t have the same charm.

The history of the good ol’ uke goes way back. During the late 1800s they were first introduced as instruments in Hawaii, where its name literally meant “jumping flea.” Well-known songs like I’m Yours, by Jason Mraz, Riptide, by Vance Joy, and Imagine, by John Lennon have familiar ukulele riffs which have contributed to the popularization of the instrument, yet these bands use the ukulele in maybe one to two of their songs, and then proceed to abandon it.

I know what you’re thinking; why would I want to design such an uncommonly played instrument?

Although the ukulele is not a widely sought-after instrument like the electric guitar, and piano, I decided to design and print it because it combines the aspects of many popular, commercialized instruments. For example, the ukulele is compact, like the violin, but is not as susceptible to external factors that may may warp the acoustics. It retains the same resonance as the acoustic guitar like the Yamaha FGX800c, but within a smaller body. It has strings that can be tuned, just like a piano, but rather than 236 strings, each with their own unique thickness and reverberation, it has 4 which are tuned to C, E, G, and A . For these reasons, and many more, I figured that a ukulele would be relatively easy to design and print, while still containing key aspects of various other basic instruments.

During the process of actually printing the ukulele, I learned many things about designing the instrument itself. One of which being, SAVE YOUR SOLIDWORKS MODELS EVERY 5 MINUTES. There is nothing more traumatic than losing a solidworks file which you had just finished after 1 solid week of work.

However, the portion of this project in which my learning fared most, was the printing, and post-processing of the instrument. Failed prints were rather frequent in the first stages of printing. During our first attempt at printing the body, we decided to orient the body to stand at a 45 degree angle, in order to print it all in one piece. Little did I know that what would be printed would look something like a bird’s nest. Because of some issues with the fan near hot-end of the bot, the print shifted, and proceeded to print midair. Although printing the body in one piece was possible, we decided to go the easier route of printing it in two separate, flat pieces.

Fast-forwarding to when the ukulele was half-assembled, I stumbled upon some valuable learning experiences. In case you didn’t already know this, GORILLA GLUE SUPER GLUE STICKS VERY WELL. Always use gloves when handling super glue. (I may or may not have learned that the hard way.)

The fretboard took several prints, but I had already expected this when I was designing the ukulele. In order to get the placement, and height of the frets just right, it would require some trial and error. This is why I made the neck and frets separate pieces in my model. The first fretboard I printed was way too thick, causing the strings to collide with the higher-up frets. This ended up producing not-so-pleasant vibrations. The fret placement was also a little bit off, causing all the notes to be disturbingly sharp.

The second fretboard was more successful, not only because the black filament made the ukulele look more sassy, but because the fretboard was skinnier, (eliminating the unpleasant vibrations) the frets were taller, (facilitating the playability) and the fret placement was shifted, but wasn’t shifted down quite far enough.

Which leads us to the third fretboard–perfection. That wrapped up project uke once and for all–or so I thought.

My crowning achievement was playing a funky ukuleke riff for the first time. Then I did something very, very, VERY stupid. I left the 100% completed ukulele in the car for no more than 45 minutes, and by the time I came back, the ukulele had completely warped. Because the body of the ukulele was so thin, it had actually folded in on itself, and left the bridge, shattered.

This didn’t upset me though; I thought of it as a way to make improvements to ukulele 2.0, that I had missed in the original. For example, I could combine the frets and neck, to eliminate the number of parts I had to super-glue together. I also had the chance to make an awesome video for the re:3D What NOT to do 101 When 3D Printing You Tube Channel!

However, after exploring this option, I realized with support material the model is still best split with the fretboard separate so I re-printed it just in time for an interview!

Over-all, printing this ukulele definitely gave me more insight into the musical world. Not only did it open up a new door of opportunity for gigabot, but it also taught me the process of trial and error, and that things rarely ever work out the first time. Another interesting thing I learned about the acoustics of the instrument, was that the PLA filament body actually had a stronger, and more vibrant resonance, as opposed to the wooden ukulele.

I hope to use this new knowledge to lead me into my next project–an electric guitar!
