Gigabot 3+ Firmware 4.2.0

Introducing the new Gigabot Firmware 4.2.0. This new firmware release features the latest version of Marlin 1.1.8 and is packed with new features that will elevate the user’s experience with the Gigabot.

Notice: This Gigabot Firmware is only for users with the Azteeg X3 Pro (GB-371 and up)  with the dual limit switch kit. This version will not work for bots with single Y limit switches. 

Here are the links to purchase the upgrade kit, new Simplify3D profiles, and to Download the Firmware

A New Look

The changes in the new firmware can immediately be noticed on the main info screen of the Gigabot. The larger font makes it easier to read and navigate. (Figure 1.)

The contents and item order of the Prepare Menu have also changed to create an easier and more accessible experience. The preheat option is placed on the top so a target temperature can be set quickly. A new and improved Change Filament routine item is shown followed by the Move Axis menu plus three axis homing actions. (Figure 2.)

About Printer is the newest addition to the screen menu (Figure 3). This menu displays useful information about the printer, such as the model number, firmware upload date, prints completed/ failed, total print time and longest print job completed. This data can be used to keep track of a regular maintenance schedule for your Gigabot.

Dual Y Axis Homing Switch

A major feature of the new firmware is the support for dual Y-axis homing switches. This feature provides more consistent performance and a higher degree of dimensionally accurate printed parts out of the Gigabot.

Previously, a single homing switch existed on the left Y motor, resulting in a carriage that was not consistently parallel to the machine frame. During a filament change, it was possible for an accidental displacement of the carriage, losing positional accuracy (Figure 4).

With dual Y axis homing switches, the machine is guaranteed to be squared to the frame every time the machine is homed (Figure 5). This will provide more consistent performance and accuracy for all prints. Paired with the new filament change routine, the Gigabot will show precise repeatability.

Shown in Figure 6 is a print completed to torture test the dual homing switch feature. A line of gcode was inserted after each layer incrementation to move the extruder aside, disengage the stepper motors, rehome, and continue printing. The results show the consist carriage squaring that the dual homing switch provides. After over 1000 layers, the tower shows homogenous layer quality with no layer shifts.

Linear Advance

Do your prints ever look like the image in Figure 7? Linear Advance is a new feature that allows users to print more dimensionally accurate parts. Under normal conditions, the extruder gear moves linearly in proportion to all other axes. However, the pressure buildup in the nozzle is not proportional to other axes and this leads to extra material being extruded at the end of each movement.

To solve this issue, Linear Advance changes the extrusion rate whenever the extruder slows down or speeds up, creating an even extrusion line regardless of the speed or change in direction.

The advantages of this feature are listed on the Marlin website and are as follows:

  • Better dimensional precision due to reduced bleeding edges
  • Higher printing speeds are possible without any loss of print quality
  • Visible and tangible print quality is increased even at lower printing speeds
  • No need for high acceleration and jerk values to get sharp edges

re:3D performed an extensive test on this new feature to determine the optimal K value for different layer heights and printing speeds. Shown in Figure 8, is a set of test specimens printed with different K values. Figure 9. shows the improved dimensional accuracy from a specific K value.

A weighted average value of K= 0.08 was chosen, improving print quality for a number of different print settings.

Check the blog post for more information:

Ditto Printing

Duplicate nozzle printing (aka. Ditto Printing) allows the user to print with both nozzles at the same time. It can produce two identical parts with the only constraint that the X length of the object is smaller than the hotend offset (~55mm on the Gigabot). This feature is particularly useful when mass producing parts, cutting printing time in half which can be very beneficial. To enable this feature, download the new 4.3 Simplify Profile for Gigabot, choose PLA Duplicate Nozzle or PC-Max Duplicate Nozzle under the Auto-configure for Material tab and Duplicate Extruders under the Auto-Configure Extruders tab. In the slicer, place only one model on the build platform and start the print. The bot will produce two identical parts.

(Note that this feature works by mirroring the left extruder to the right. Only the left filament runout sensor will be active and the right will be inactive.)

re:3D uses this feature to increase the speed of printing in-house production parts (Figure 11,12).

This feature can also be used to infuse parts together! Like this crazy dual color infused Marvin or 3DBenchy boat shown in Figure 13 & 14.

Filament Change Routine

The new filament change routine provides a series of walk-through interfaces that guides the user through the entire process. The user first selects the extruder and material type that needs to be changed. (Figure 15)

Shown in Figure 16 are a series of walkthrough LCD screens. The Gigabot will first heat the desired nozzle, then automatically unload the filament. The LCD will then direct the user to unload the filament and insert new filament. The filament will automatically purge and ask the user if they want to purge more or continue printing. There are also added safety features that will unheat the nozzle if the machine has been idle for a minute.

Previously, filament changes were tedious with the cable chain obstructing the workspace. With the new firmware, the nozzle park position is on the right side, avoiding all obstructions and allowing for easier filament changes. (Figure 17.)

Please Note: For filament changes from high-temperature material to lower temperature materials (Ex. Polycarbonate to PLA), Please manually heat the nozzle up to the melting temperature of the higher temperature material, switch materials, then purge 200mm of filament and lower the temperature down for the second material. This will clear out the nozzle of any previous material to prevent jamming.

Continuous Printing After Filament Change

Continuous printing after filament change is a feature specifically designed for the long prints that the Gigabot produces. Often times, the Gigabot uses an entire spool of filament and upon filament runout, the machine pauses and waits for the user to change filament. Production time will dramatically increase if the user is unavailable.

With the new Continuous Printing feature, the user loads two spools of the same filament into both extruders. When the first spool runs out, the Gigabot will automatically unload the filament, load and prime the second nozzle, and continue printing. This feature is listed under Controls> Filament> Filament Runout (Figure 18). The user can choose between two filament runout features, pause for change or continuous printing. These options are also available during mid-print so the user can change settings as any given time.

For very long prints, once the second filament spool starts printing with the left nozzle, it is suggested to pause the print and load another spool of filament into the right nozzle.

Shown in Figure 19 & 20 are some of the largest prints that re3D has done. The print time could have been dramatically shortened with the use of continuous printing after filament runout.

Babystepping for Perfect 1st Layer

Babystepping allows the user to adjust the Z height at very small increments to achieve a higher quality first layer. To use this feature, double click the encoder during the first layer of your print until the LCD screen displays the Babystepping screen as shown in Figure 21. Scroll the knob to move the Z up or down (clockwise to move the nozzle away and counterclockwise to move the nozzle closer). Babystepping can also be activated through a M290 gcode. Look at that perfect first layer in Figure 22!

re:3D uses this feature to accommodate for the expansion of the heated bed during high temperature prints such as polycarbonate. A M290 Z0.25 moves the nozzle 0.25mm away from the bed and M290 Z-0.25 moves the nozzle 0.25mm towards the bed.

As seen in Figure 23, Babystepping can dramatically improve the first layer quality. At the start of this print, the nozzle was too far from the bed and the babystepping was adjusted to -0.217mm. After the adjustment, a perfect layer line was achieved.

Zero to Factory: Why We’re Sharing our Experiences Being Scrappy

Week 1

As an optimistic group of underdogs we firmly believe that anyone, anywhere, anytime, should have access to their own personal factory while controlling their supply chain. With this vision we launched re:3D Inc– a social enterprise committed to making human-scale 3D printing available to emerging markets.

Our flagship technology is the Gigabot, an open-source 3D printer, which cost per scale remains one of the most affordable industrial solutions on the market. We launched Gigabot on Kickstarter during participation in Start-Up Chile, which catalyzed our sales and gave us a small nest egg to get started. However, producing & shipping a toilet-sized 3D printer required many considerations not originally scoped in the budget that drove our initial price-point. Rather, we found ourselves investing as much energy into standing up a garage-based factory that is now scaling into a proper warehouse in Houston as well as a satellite office in Austin. Wanting to save money on your business utilities? Have a look at sites that offer business electricity comparison deals and see if you can start saving money on your bills.

With an ultimate goal to enable Gigabot to 3D print from plastic trash, we’ve had to work hard to preserve our social genesis despite being lean. One reflection of our passion for impact is though the Gigaprize, whereby we donate one Gigabot for every 100 sales to an organization working to make-a-difference through 3D printing.

Why we are starting a blog on Medium:

While re:3D keeps a blog that highlights our activities in the affordable, large-scale 3D printing domain, we recognize that the our experience is part of a larger narrative. Our story has admittedly been both physically & emotionally taxing as we continue to invest our savings, blood, tears, sleep, ruined clothes & a lot of giggles into building our future. By leveraging the reach of Medium we humbly submit our successes & failures for consideration to others pursuing bootstrapping a hardware company.

Beginning today, and subsequently for the next 52 weeks, we intend to share our open-source, socially-focused, boot-strapped experiences in hardware. Although initially we’ll be offering ourselves as a case study in crowdsourcing, inventory management, quality controls, export compliance, contracting, new tech sales, pitching, and customer support, we’re hoping to feature guests posts from other hardware veterans as well. Other businesses looking to improve the management of their facilities and make other aspects of their operations more efficient may want to consider implementing Axxerion’s computerized maintenance management system to do this.

We welcome requests on future topics, offers to guest blog, and feedback on whether we should continue documenting our lessons learned once the series concludes!

The GSA Advantage: Part 1

As a self-identified “knower of totally random facts” I pride myself on the amount of odd pieces of information that happen to be floating around in my brain.  And while I did have some idea about what GSA was; going through the process of getting awarded a GSA Contract for re:3D was one heck of a learning experience.

So lets start simple, what is the GSA?

The General Services Administration (GSA) is an agency within the federal government that helps the government to function.  That is their job in the most basic and simple terms I could come up with.  Government real estate (leasing and management), government acquisition services (procurement and contracting), plus best practices and policy guidance, all of these things fall under the GSA, and I am sure there are loads of other functions that I don’t even know about.

I was most familiar with the GSA through their GSA Auction website.  Do you ever wonder where you can buy an airplane, old refrigerators, and 5 barrels of spent brass shell casings? 


Why the answer is simple – bid on it, the GSA is selling!! sells anything and everything that the federal government and it’s agencies no longer want.  I personally enjoy the listings for old lighthouses, I mean – who doesn’t want to own a lighthouse? My favorite listing by far was the lighthouse for sale (which had multiple bidders!) that had a Coast Guard maintained fog horn which operated a decibels “higher then recommended for the human body” – It would be like music to my ears as I sipped margaritas in my lighthouse cupola.

Why was it important for re:3D to get onto a GSA Contract?

Selling to the federal government is difficult.  We recognized that we had more and more interest from different federal agencies who wanted to purchase Gigabot.  These purchases took a long time, because the government buyer would have to get through a lot of red tape and a lot of different hoops in order to purchase our products.  So in the interest of saving our buyers time, we took on the task of becoming a government contractor and getting on a Multiple Award Schedule.

What is a Multiple Award Schedule?

A Multiple Award Schedule (MAS) is basically a category that government contractors apply to sell in.  For instance, re:3D is in Schedule 36. Schedule 36 is The Office, Imaging, and Document Solutions category, and within each schedule are sub-categories or Special Item Numbers (SIN), in our case SIN: 51.400 – 3D Printing Solutions. So to put it all together, and really test our acronyms – re:3D is a MAS 36 SIN 51.400 GSA Contract Holder – hooray!

What does that mean for me?

The answer to that, as always, is: it depends.

Are you just a person, with no government connections? Then this post is really just informative, and won’t have any real bearing in your day-to-day life, but stay tuned because I will follow-up with an even more in-depth meat and potatoes post about getting a government contract -real edge of your seat reading.

Are you part of a government agency or subcontractor who is allowed to purchase products through GSA? Do you need a Gigabot 3D Printer? Then you’re in luck!

The reason companies are required to go through the GSA contract procedures are numerous, but the most important one for the government is the guarantee that the government buyers are getting the best price possible.  Which means that all pricing of all products is pre-negotiated with your assigned GSA Contracting Officer (Hi, John!).

Contract awardees (that’s us!) are then able to upload their products onto the GSA Advantage website (, think of it as Amazon for the federal government.  Government buyers can then search for products to purchase, everything from pens, to desks, to 3D Printers can be purchased through the GSA Advantage website.

Through the GSA Advantage we have created Federal Packages, available only through GSA.  These packages include Gigabot (Standard, XL, XLT), the wheeled cart, PrintinZ, Simplify3D, 3 Year Warranty, and CONUS shipping.  Printing HUGE has never been easier to attain for government buyers!

Over the next year we are going to be putting a lot of effort to marketing our products to government buyers.  It isn’t enough just to get onto a Schedule Contract, you actually have to sell if you want to keep your contract.  Our goal is to look for opportunities to speak and exhibit at government-centric events this year, with the hopes of talking to the right people to make some sales!

Happy Printing!



I’m going to be forthcoming in this introduction and tell you that I have no background in 3D printing. In fact, working with the community during this year’s Gigabot Giveaway was my initiation into this world and network, and it has been nothing short of inspiring. My name is Beth Eanelli. You may know me as the community manager of the New Year’s Gigaprize: 2016 and I possibly sent you an email or asked to use one of your photos in a social media post.

As I mentioned, this was my introduction into 3D Printing, and I have been simultaneously humbled and overwhelmed by the innovation in the field. I had heard of 3D printing, read about it in magazines and articles, but as I was graduating University, I remember the first 3D printer coming to the Engineering Department, but I never had a chance to see the machine, or to watch it come to life.

My background is in public health and international development and I have dabbled in social impact, though never in the tech realm. I returned just in time for the holidays in 2015 after spending two years living and working as a health volunteer with the Peace Corps in a little country called The Gambia. The village I lived had no electricity and no running water, and health issues like Malaria and diarrhea still run rampant. In short, there were minimal resources and with the capital being across the country and transit towns having sporadic electricity and no consistency with products sold, managing projects and creating programs required constant rescheduling and a lesson in being a true MacGyver.

The first time I met Samantha was at Unreasonable Impact, a program created with Barclays, which brings together entrepreneurs working towards social impact and change to build community, create jobs and help the entrepreneurs maximize their influence (blog to follow). In her introduction to re:3D, Samantha described the printers as having the ability to be mini factories in countries with little to no resources. Having seen the possibilities of what 3D printers could bring to communities such as the one I lived in, I was hooked, and Samantha and I spoke at length about what re:3D had and continues to accomplish. I imagined my community with a 3D printer, the nearest town with continuous access to a makerspace, and couldn’t believe this was a reality in some places because of re:3D. I learned of re:3D’s 1 Gigabot 3D printer donation for 100 sales during one of many conversations with Samantha and we connected right after the program. Shortly afterwards, I was asked to be the 2016 Community Manager for what was formally called The Great Big Gigabot Giveaway, renamed the Gigaprize due to Unreasonable mentor feedback that the opportunity should not be framed as a handout, rather recognition for global citizens doing extraordinary things to improve society.

I’m going to be honest and tell you that I watched each Giveaway entry video with an open jaw. And while many of you know that 3D printers can be used to print prostheses and create Makerspaces, I was learning along the way, consumed by the novelty. Some of our Gigaprize: 2016 applicants are impacting their communities by printing prostheses for low income families, using plastic waste to create clean energy, using makerspaces as a learning tool in schools and libraries and to keep students in school. There are entrepreneurs among us using plastic bottle tops as filament and creating jobs for those who are unemployed in the industry. Each applicant is a catalyst, an innovator and an inspiration and I am looking forward to the chance to see what everyone continues to do.

The most difficult part of the Giveaway was choosing just one winner to receive a Gigabot 3+ kit. Each person and group is contributing to their community in a profound way, so choosing just one entry isn’t easy. Emergency Floor, the winner this year, has an amazing story. They’re using the Gigabot to prototype flooring to be placed in refugee camps, providing refugees living in these camps warmer, safer and more hygienic. Amazing, right?

I also want to express my gratitude to the judges who helped us make this difficult decision, and brought their vast knowledge and range of expertise to the table. We could not have made this Gigabot giveaway possible without each of these individuals.

Lastly, I want to express my gratitude to the applicants and the 3D printing community for your ideas and innovation, your drive and passion, and for allowing me insight into this world. I also want to that the thousands that voted to share their support for such phenomenal idea. If you didn’t have a chance to watch the entries as they were live, you can still do so here. Want be introduced to one the amazing applicants? Feel free to send me a request!

Happy Printing!

Pitching for a Circular Economy: Why We Went to Hello Tomorrow in Paris

With the momentum of the Bunker Austin win behind us, Matthew & I flew to Paris and grudgingly paid the shipping for Gigabot to meet us in the gamble that either we would either 1) Get a selfie with Mr. Bloomberg (and much needed press) 2) meet someone willing to cover the bond & buy the ‘bot in France, or 3) we’d win our pitching track & return net positive.

It was a huge risk that our company really couldn’t afford in addition to our discounted flights and a shared hotel room (thankfully Matthew has a very supportive girlfriend with access to deals!). But as Matthew & I firmly believe printing from reclaimed plastics takes an ecosystem of problem solvers, which frankly needs more support, we felt that we had to attend once we were notified that we were pitching finalists.

We also were also intrigued by the premise of Hello Tomorrow, which unites technologists, academics, and corporations to solve the grand challenges facing humanity. 3D printing from trash appeared to be a perfect fit, and Gigabot had to be there. With the promise that we would print a kickass logo during the event, the incredibly kind Hello Tomorrow staff agreed to find space for Gigabot.


Matthew arrived in Paris first from Houston, and greeted the oversized crate while I gave a talk on the social potential of 3D printing at Singularity University in effort to be considered as a speaker and then flew out from San Francisco.


As we had witnessed at other events this winter, Gigabot arrived in perfect condition & was up & printing without any calibration. Jet lagged but determined to give it our all, we stayed up late practicing for the pitch competition the next day.


The day kicked off with an outstanding keynote by Imogen Heap, who demoed her novel gloves to give more dimension to sound. Afterwards, we were humbled when she visited Gigabot and mused with us re: the intersections of community, technology & creativity. We (err….I) shamelessly asked to take a pic in return for a print.

Matthew unfortunately had caught a terrible cold from the travel & lost his voice, but powered through the day, ensuring Gigabot was tended to, I ate some food and we were set up for success at the competition.  We weren’t the only team committed to (or perhaps delusional about) our cause. The other startups were just as hungry to further their passion by building connections with other attendees, and meet corporations in order to foster partnerships. Even the Hello Tomorrow staff exemplified commitment to curating an ecosystem of problem solvers & pioneers, with a teammate receiving a Hello Tomorrow tattoo on stage live!

After witnessing one of the other finalists, Tridom, bring their impressively large robot to the stage, we seized the opportunity to roll Gigabot over as well, leaving the poor Hello Tomorrow staff with little space, and lengthy power chords to manage. However it was worth the inconvenience as our respective machines found love at first print & the selfies of Gigabot & Madeline were adorable.

Tensions mounted as each co-founder took the stage and presented the benefits our ideas offer society. The competition was fierce. Each company had significant traction, an impressive technology, and solid teams. Further adding to my nervousness was the realization that not only was this strongest cohort we had ever pitched against, but the judges were tough!  With Matthew manning Gigabot, I stumbled through slides & questioning. The judges challenged the market for 3D printing as whole as well as the profitability of printing from waste & thus eliminating the feedstock from what largely is a blade & razor model today. While I could certainly have done better, I did my best to build upon lessons learned from Atech in Aruba. I shared the promise of the growing industrial 3D printer segment, the opportunities to increase the market by enabling more people to fabricate onsite, and upside that direct drive pellet extrusion expands the library of printable materials while decreasing print times. Stepping off the stage I was sweaty, shaky, and confident we had lost. I apologized to Matthew, congratulated the team I thought had won and set our sights on the meetings we had arranged with L’Oreal, Michelin, and Airbus.

The afternoon flew by. We gave out all of the flyers we brought, and pitched several blue chip companies to give us access to their post-manufacturing waste. Gigabot had a blast 3D printing Hello Tomorrow logos for the staff & we found that while we likely hadn’t won our track, an unexpected gain from the event was that we had found our tribe.

The attendees were just like us: problem solvers spanning hard science, technology & impact. We met nonprofits such Claire from MSF (Doctors Without Borders) and academics from around the world that challenged us with their questions & feedback. Aside from the criticism we fielded from the pitch judges, we found the Hello Tomorrow community truly understood our vision & was incredibly supportive. Our only regret from the event was not having more time & resources to stay in Europe with Gigabot to follow-up on the multiple insightful conversations we had (or in Matthew’s case had pantomimed).

Tired, but encouraged & full of great French cuisine we caught a few more hours of sleep and dug out any remaining flyers we could scrounge up for a possible meeting with Mr. Bloomberg the following morning. We also stole an hour to sample French food- my taste buds were blown away!


Meeting the former mayor of NY turned out to be a challenge as he was a popular man, and despite our best efforts we were unable to wrangle a selfie. We did however manage to meet a number of amazing people and took the time to visit the other exhibit booths. Before we knew it, the time had come to join the audience at the big stage and learn who had won the event.


Coincidentally Matthew & I ended up sitting next to the team from Haelexia, which I was convinced had won. We argued about who was about to take home 15K euros until the programming began, and our track was announced first. To my utter surprise our name was called, and I wished I had taken the time to touch up my makeup, & brush my exhibit – day hair & coffee stained teeth while stumbling over legs and the sea of people between us & the stage.


I arrived on stage with watery eyes and speechless as we received a hug & trophy from Airbus. You can imagine my consternation when I was then handed a microphone and told we had the next two minutes to pitch two rows of judges for 100K. Feeling ill prepared, I gave everything I had left in an enthusiastic and emotional appeal. While 15K would fund our prototype within a year, 100K could bring what we see as inherently right to commercialization. I did my best and knew that while willing the Grand Prize was a long shot, I was humbled to share our passion with such an amazing group. I also secretly hoped that Michael Bloomberg was watching from the sidelines and would offer our much sought after selfie.


The best part of the night however, was backstage. As each other track winner joined us, we were blown away by their technologies and the awesomeness of each team. We also noted a curious fact: half of the track winners were pitched by females and/or also came from gender co-lead teams like us. We quickly assembled a cheering squad to celebrate the other winners as they joined us backstage and sponsor Chivas ensured there were plenty of drinks for the multiple toasts that ensued.


After all had joined, we headed out to join a big band for the announcement of the Grand Prize winner, Lilium. Although the money would have provided what we desperately need to scale our vision to 3D print from waste globally, we were thrilled for their team!

We joined Gigabot & all for the after party and then rushed to pack up Gigabot before security threw us out.

The next day we caught a train and headed outside of Paris to meet a local Gigabot owner. At re:3D we try to visit customers when on the road as it not only provides valuable business intelligence but also is an incredibly rewarding opportunity to connect with the customers personally. We had a blast, and were super honored when they blessed us with a guided tour of the city on the way home and drove us to the Eiffel Tower. We couldn’t go up the monument due to the tools in our backpack, but we were fortunate to walk around the legs and stare into the impressive infrastructure for several minutes.

After pausing to reflect on the engineering & creativity above us, we grabbed dinner & prepped to leave.


On the flight home my mind was filled with lights, relationships, and next steps. To all who made Hello Tomorrow and my first trip to France a success: thank you. Thank you for believing in bootstrapped underdogs, and for giving us a platform & resources to make the impossible slightly more tangible!

Happy Printing!

Pitching for a Circular Economy: Part 2- Why We Presented our Big Idea to Bunker Labs Austin

Sharing our Vision to 3D Print from Reclaimed Plastic in Texas

After reflecting on Aruba at Atech2016, Matthew and  I were convinced that our vision to 3D print from reclaimed plastic, albeit premature, was a passion we were compelled to continue sharing. We also felt it was imperative that in addition to casting our vision overseas, it was just as important that we pitch the opportunity to join our cause to our colleagues in Texas.  For this reason, I took a break from travel to join Mike Strong, Gigabot and Todd at the 2016 Austin Bunker Muster, a short walk…err roll….down the street from our Austin office.

We arrived a little sweaty, but stoked to assist our friends at Austin Bunker Labs in setting up for their annual fundraising event. Mike & Todd volunteered to help with setup & lighting while I paced around the block, practicing for the pitch competition that evening. The Muster in Austin was a unique event that brought together participants and partners for a day-long event of veteran entrepreneurs pitching their businesses, an Idea Lab for speakers, and a marketplace to buy products from veteran-owned small businesses. As a veteran employer & owned company, our entire team was humbled to support the festivities.

The day flew by as we listened to talks, demoed Gigabot, and chatted with old friends such as Marcus from Vthreat.  We also made new relationships, including JP Morgan Chase, re:3D’s new banker!

As the evening drew a close, I found myself incredibly nervous as we prepared to pitch against 20 peers. Unlike past competitions, this time we took the stage in front of friends, not strangers. These contestants were heroes we revered, who had sacrificed time & limbs for opportunity. Taking the stage with them was perhaps the greatest honored of my life. Normalized with stage-fright and determined to support our buddies, we celebrated each other and our companies’ successes to date.

During the event, I struggled to convey our strategy for repurposing post-manufacturing waste into 3D printers in less than 90 seconds. Further adding to the anxiety was the realization that without winning, we would not have the resources to begin explore 3D printing from recyclables in Q1 2017.  It was only by leveraging the encouragement from friends like Travis from Stump Armour we presented our desire to 3D print from trash. With so many outstanding competitors, we were stunned to learned the community had honored us with $5K to make our idea a reality!

Where do we go next?

With $5K in hand we re:3D received much-needed affirmation that 3D printing from recyclables was not only something inherently right, but offered benefit for our neighbors. Taking a selfie with Austin Mayor Steve Adler gave us certainty that Austin & the Bunker community could incubate our audacious idea!

~Happy Printing!

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

  • 5- Great adhesion was achieved with no temperature manipulation.

Stringing (1: lots – 5: none!)

  • 5 –No stringing was observed with our settings.

Shrinkage (1: lots – 5: none!)

  • 5- The filament extruded and cooled with no shrinkage.

Interlayer adhesion (1: terrible – 5: fabulous!)

  • 5- Perfect!


  • We were first contacted by the Fiberlogy team last fall, who offered to send us a spool of their filament to evaluate on Gigabot. We recognize that the community is fortunate to have several PLA vendors to select from, however as not all PLA is created equal, and were eager to vet a European supplier for our customers accross the pond. Fiberlogy HD PLA boasts that it is a high quality and dependable PLA that has the added benefit of increasing strength when annealed.
  • Seeing that we offer a limited color selection in our store that ships from North America, we are always eager to test additional PLA sources.
  • This material appears to yield consistent, quality prints.
  • Filament size consistency was excellent and no breakage was evident in the 1 kg roll we examined, suggesting it was well mixed.
  • The packaging and spool design was futuristic, intentional, and of high quality.
  • No curling was observed in any of the 4 prints created.
  • We used the mid point of the temperature range that the manufacture provided (200-220C). No guidance was given for settings aside from temperature, so we used the standard Simplify3D profile on
  • The unboxing experience was outstanding and highly professional.
    • A batch number was provided for traceability.
    • Manufacturer recommended settings were easily referenced on sticker located on the packaging.


  • After printing the four objects in our protocol, I support Fiberology’s claims that they produce high quality PLA and would recommend it to our customers.
  • Upon review, we would also recommend that we include this filament in our ASTM test sample research.
  • Per the guidance on their website , I did attempt to anneal the PLA in my oven at home, however without empirical testing against similar objects printing in ABS, I can not testify to the strength claims Fiberlogy asserts for annealed HD PLA.
