Convening Global Community: Thank You CES 2019

CES 2019 was jam-packed with activities and innovations that sprawled throughout Las Vegas with over 180,000 attendees, exhibitors, and speakers. The conference and exhibition activates across giant venues in Las Vegas including The Venetian, Sands Expo Center including startup innovation arena Eureka Park, and the Las Vegas Convention Center. Companies and innovators on the spectrum of industries and size exhibited their latest work, from life-size drone helicopters, robots beating humans in ping pong, pretty much anything “smart” you can imagine or yours truly, showing our large scale 3D printer printing from plastic waste. We posted some insights on our schedule and first day at CES and here is the remainder of our insights, adventures, and recap of our first CES experience. All in all, CES was about convening community from around the world to showcase and connect over their latest innovations and we wanted to write a recap and thank you note to our community who have supported ours.

Gigabot X @ CES

Our debut at CES 2019 wouldn’t have been possible without instrumental partners who gave us platforms to exhibit our new technology, Gigabot X. Gigabot X is a large scale (or large format if you prefer), affordable 3D printer printing from pellet or flake plastic. Pellet printing in and of itself drastically lowers the cost to 3D printing 10 times and prints up to 13 times faster than other printers. Even more so, after various peer-reviewed research with Michigan Technological University – Gigabot X has been validated printing from multiple types of plastic waste in pellet and flake form. To showcase these developments almost exactly a year after we won the WeWork Creator Award and received funding from the NSF SBIR Phase I grant as well as launched Gigabot X on Kickstarter, it was a huge privilege to have our hard work on display to the global community who convenes at CES – meeting industry leaders, makers, fellow creators, and enthusiasts from all over.

We also exhibited some Gigabot X and Gigabot  prints such as 3D printed coral (straight from 3D scans of the Caribbean), a skateboard 3D printed from recycled plastic, vases, trashcans, architectural pieces, our infill educational tool, 3D printed medical devices, coffee picking baskets, prosthetics, replacement parts and more real-world examples of the innovations around the world, across industry, all with the commonality of solving problems utilizing Gigabot and 3D printing technology . While we’re putting the final touches on Gigabot X before it’s commercially available, the positive feedback, inquiries, and pre-orders of Gigabot X were a major accomplishment of our time during CES. However, as a community-driven organization, this latest accomplishment wouldn’t have been made possible without a world of supporters (yourself included) and some of the major supporters who have gotten us to where we are today. This gratitude was proudly broadcasted across Gigabot X’s headboard (see below photo). Beyond that, we wanted to write a recap and thank you note to CES and those who made it possible for us to be at CES, get to CES and showcase our vision.

Thanks to National Science Foundation, Small Business Innovation Research, and Small Business Association not only for making the NSF SBIR grants available like the Phase 1 grant that helped make Gigabot X a reality but also for the support and partnership to showcase Gigabot X at the U.S. Government Startup connection booth in Eureka Park and ongoing support. We also got to meet other amazing organizations co-exhibiting in the U.S. Government Startup Connection booth like Ampaire on a mission to provide the world with all-electric powered commercial flights that are affordable, quiet and environmentally conscious, and Hivemapper, Learn With Socrates, and Gen X Comm. Despite the government shutdown which created some curveballs, our partners at NSF and SBIR were integral to our CES presence and getting to debut Gigabot X to the community. Thanks to USPTO for being there!

Connecting with WeWork and their Senior Construction Partner, Brian Ringley, at CES was another major milestone. The one year anniversary from when we won the $1M WeWork Global Creator Award occurred during CES and on the same day at CES, Brian met his new Gigabot X heading his way, one of the first to be delivered to Kickstarter backers from the successful launch last year. It was an amazing time to connect with Brian and celebrate this full circle collaboration: from winning the WeWork Creator Award to launching the Gigabot X prototype on Kickstarter to working together on Gigabot X’s the evolution from a beta bot to delivering it in person on perhaps one of the biggest platforms and convenings for electronics. We also got some great snapshots with Brian’s first print and his kickflips on our 3D printed skateboard from recycled plastic!

re:3D wins 1st prize at Techstars Robotics Pitch Competition!

If you know our story, you know it begins with Kickstarter – and Kickstarter continues to be a key community partner and powerful platform that supports us as we launch new evolutions of the Gigabot family such as Gigabot X last year to its first beta users. We were grateful to meet with the Kickstarter team, like Clarissa, and community at some amazing meetups after hours with a global network of creators and partners like Hackster and Dragon Innovation.

We are forever grateful for our friends and supporters who have gotten to where we are today! Arguably one of the proudest highlights of CES was reuniting with one of the first Gigabot owners, Doug Mockett of Mockett, who came to say hi to us at CES from California. Still to this day, their two Gigabots run around the clock and they lovingly call them their “workhorses”. We met up with some other customers (like one using Gigabot to 3D print entire life size inventory robots) and even suppliers like LDO Motors.

Startup Chile fellow entrepreneurs Waverly Labs exhibits at CES

We got to catch up with friends from former accelerators like Waverly Labs from Startup Chile, our first accelerator we joined when we launched in 2013. We met up with one of our mentors from Parallel 18, Alicia Syrett. We also said hi to fellow Unreasonable Impact alumni on a mission to create solutions and jobs in the green economy such as the teams from Heatworks and Breezometer exhibiting in Sands Halls.

We spent one morning getting to tour the local Afwerx office in Las Vegas, an organization creating innovative and crowdsourced solutions for the most critical problems affecting those in our Air Force and an organization especially close to our heart with two teammates Samantha and Kara actively involved in the military and Air Force. We also got to see our partners at IEEE and Finn Partners at an evening event, some great partners who share aligned values with their mission to foster technological innovation and excellence for the benefit of humanity.

A huge thank you as well to partners and press who acknowledged us in their pieces, we can’t say enough how grateful we are for your recognition. Alice’s Elizabeth Gore included us in an Inc article with a major announcement on the bright future of diversity in tech, Jean Baptiste Su noted us in Forbes top 22 innovative technology startups to watch at CES and Beau Jackson’s 3D printing round-up at CES in 3D Printing Industry gave us a nod. Thanks for these platforms and writers for sharing our story! We hope to continue to share more on our developments, diversity, and problem solvers around the world breaking limitations with 3D printing.

We are so grateful to CES for giving us a big platform to jump off of in 2019 as we dive into a year filled with new innovations, stories and leaps forward toward a world empowered by sustainable and locally driven manufacturing. Thank you and stay tuned for some more updates and footage coming your way. Don’t forget: #ReduceReuseRe3D

p.s. If you were following our road trip to CES and are curious about the adventures of re:3D after official CES festivities, we packed up Gigabot X in our beloved Uhaul and headed back to Texas the way we came: 1,500 mile road trip. We traversed from Las Vegas to Tucson, then on to El Paso where w dropped off a Gigabot at the University of Texas El Paso's W.M. Keck Center for (extremely rad) 3D Innovation in partnership with America Makes. We then took a break to rock climb at McKelligan Canyon in El Paso before heading back to Houston, Austin & San Antonio.

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!

Getting a Grip : Part 1

Getting a grip on your 3D printer filament-Part 1

With the rise in popularity of low cost 3D printers for use in homes and small business many new printer designs have recently arrived in the market. The cost of ownership for 3D printers is coming down which is driving up access in new markets. With a customer base growing outside of engineers and tinkerers it is important that 3D printers must remain near 100% reliable with near zero failed prints due to mechanical and electro-mechanical malfunctions.

One of the leading causes of print failure is the filament feeding mechanism. By surveying the literature and leveraging our current experience in hardware development we have identified a gap in the knowledgebase for understanding the mechanics and operations surrounding the extruder drive gear commonly used on FFF type 3D printers.

We have found reliability of the filament feed gear is dependent upon three factors 1) amount of contact surface are between the drive gear and the filament, 2) depth of the gear’s tooth engagement into the filament 3) number of teeth engaged in the filament at any one time and 4) the direction of the force vector imparted from the filament drive gear into the filament. R&D at re:3D delved into this problem and below is result of their work.

Figures 1 and 2 below shows a 3D rendering of the filament drive gear “Jaws” that will be mounted to the shaft of a geared NEMA 17 stepper motor.

Figure 1. Jaws filament drive gear. Figure 2. Mid-section view of Jaws filament drive gear

The Jaws filament drive gear is machined using a four axis Bridgeport CNC milling machine. In the design process our aim was to optimize the four variables stated above.

  • The amount of contact between the drive gear and the filament is maximized by machining the gear teeth using a cutting tool of the same diameter as the filament it will drive. In our case the filament is 6.0mm in diameter.
  • The depth of tooth engagement was optimized by balancing greater tooth engagement with number of teeth engaged into the filament at any one time. If the tooth engagement is too shallow there will be too little surface area and force imparted to the filament and the teeth will slip and shred the filament. If the tooth engagement is too great the risk of plastic deformation causing the filament dimension to be out of spec for the hot-end and will cause jamming of the hot-end during printing.
  • The number of teeth engaged into the filament at any one time is important in maintaining a smooth and constant push of filament into the hot-end. Consider the job of the filament drive gear is to transform the rotational motion from the stepper motor into straight line movement of filament into the hot-end. If too few gear teeth are engaged into the filament the linear motion of the filament over time will assume more of a sine wave pattern than a constant straight line movement.
  • The force vectors should be directed in the downward direction as much as possible to increase the conservation of energy in the system. Any forces imparted into the filament in the lateral direction will cause plastic deformation of the filament and not translated into pure downward force of the filament feed. It should be noted there will always be a certain amount of lateral force experienced for the pure fact that the drive teeth will need to be engaged into the filament. By studying the section view in Figure 3 below you can see the depth of engagement, the number of teeth engaged and the force vector for a 25 tooth drive gear.
Figure3 Force vectors
Figure 3. Tooth engagement, number of teeth engaged and force vectors

We are extremely excited to have optimized the design and manufacturing of this advanced filament drive gear for FFF style 3D printers. You can view a short video of the machining process on our re:Tech YouTube channel:

Stay tuned for part two in this series where we will perform data collection and force measurement in a real world application of the Jaws filament drive gear.
