On Beer and 3D Printing: Tap Handle Musings Part 1

If you have been following our social media accounts or exploits online, chances are you’ve witnessed multiple references to craft beer & roadtrips. We’ve also been guilty for using a #beerforscale next to our human scale 3D prints.

Chief Hacker shows off his super-sized 3D printed GE engine downloaded from Thingiverse using a Shiner Bock for scale.

As we’ve connected with makers across the globe, we’ve encountered a disproportionate number of other 3D printing enthusiasts who share a passion for home brews. Over stouts & porters (and an occasional hefewiezen), we began to muse with tap masters worldwide on the synergies between the additive manufacturing and brewing cultures, which revealed multiple overlaps.

Below are some similarities we’ve witnessed between our industries:

  • Brewers are makerpros too
    • Many of the tap masters we chatted with shared that their career started out as a hobby. A bucket and oversized pot quickly was upgraded to a small still, which serviced crowdsourced recipe requests for friends and friends-of-friends. Like so many of us now running 3D printing companies, successful breweries are an amalgamation of passion, friends, curiosity and a little hardware hacking.
  • Both movements are changing policy
    • As state and federal law restrict scaling microbreweries, many beer enthusiasts such as Raise Your Pint in Mississippi suddenly found themselves immersed in state politics as they lobbied for deregulation. 3D printing startups sympathize as we struggle to make sense of lack of industry specific export codes, open source policies, debate around the ethical use of 3D printers and the slow realization that the government is unprepared for exporting personal factories worldwide. An artifact of explosive growth, participants in both the craft beer & the 3D movement have accidentally found themselves immersed in policy & regulatory discussions.
  • 3D printing and brewing is as much an art as a science
    • While both of our industries are ultimately contingent on chemistry, whether it be polymers or yeast, little academic rigor has been applied to craft brewing or FFF 3D printing. We therefore depend on instinct and basic scientific probing to ensure consistency & quality.

  • We’re building factories
    • Whether you’re making a bottle of beer or a Gigabot, once you commit to commercialization (even in limited quantities), you’re forced to stand up shipping, compliance, and production. Within a few months, a small-scale factory emerges, with an impressive infrastructure investment (usually from the founder’s pockets).
  • We need significant capital outlay, that often is accomplished without a VC
    • With the exception of growth stage breweries (e.g. Laganitas), most microbreweries are intentionally small. As non-traditional business owners we chatted with borrowed from their 401K’s, installed the best investment apps uk, and got loans from families to bring their dream to reality. Not surprisingly, most founders we encountered were in their 30’s, 40’ or even 50’s, having accrued a nest egg to overcome the risk and initial expenditures. Breweries, like 3D printing start-ups tend to gravitate to non-dilutive options for initial funding and seemed more concerned with making a sustainable business than posturing for quick acquisition.

  • Our cultures represent a lifestyle & community is core to our mission
    • Let’s face it.  No one wants to drink alone. Concurrently most hobbyists are only as successful as the last 3D print they shared publicly. Start-ups in both domains have calendars full of events to engage enthusiasts of all levels, because the heart of what we do includes sharing and dialogue. Yoga and trivia nights are no stranger to local breweries. Similarly most 3D printing start-ups host regular meet-up and grass roots efforts to provide education, good WiFi and a place to swap ideas.

Pitching for a Circular Economy Part 1: Why We Went to Aruba

Musings From Our Amazing Experience at the ATECH* Conference

As I sit on a plane flying in the opposite direction of Aruba I feel there is nothing more important than finding a way back. You see, Samantha & I spent the past three days as co-founders immersed in a new culture with new people and pitching an idea that is new and maybe just ahead of it’s time. The event that brought us all together is Atech2016. There exist in the paradise of an island nation of Aruba a group of inspiring founders who for the second year now have decided to put their money on the table. These visionaries invite tech savvy entrepreneurs and guest speakers to discuss thoughts and ideas on topics ranging from mobile banking & blockchain technology. I’m just glad we did research into sites like https://beincrypto.com/tag/coinbase/, as this meant that we were kept up to date with all things relating to the blockchain industry. We even looked into wearable tech & social inclusion from the perspective of Burning Man to inspire each other as well as the local Arubans how we as a society maintain relevance in the age of acceleration that we are living.

Gatherings like Atech2016 are really the nexus, bringing together in one place a group of young individuals with passion, focus, and hunger for change. With connections made, and new ideas formed we are all contemplating our next steps as we fly in the opposite direction of Aruba. We feel honored to have been part of such an event and encouraged by many Arubans who resonated with re:3D’s vision and our pitch for the Atech and Aruban communities. We were stoked to be named finalists in the pitch competition, and, while we didn’t win left more determined than when we arrived.

Several things became clear to us in the few short days we spent on the island:

  1. Arubans are ready, in fact hungry, for greater technology. Meeting and talking to the young men and women volunteering at the conference we felt their excitement for 3D printing as well as other technology on display.
  2. The island nation of Aruba is resource constrained and imports the vast majority of all their physical goods. There is very limited manufacturing on the island.
  3. With an economy largely based on tourism and very little to nonexistent recycling program there is a growing problem with trash and landfill space.

Our goal and dream, that which we pitched to Aruba, was that re:3D would engineer and manufacture the prototype hardware needed to take the first step in 3D printing useful objects from plastic trash. During our few short days at the conference, we reached out to community leaders, local entrepreneurs, Aruban schools and universities and well as hotels to partner in the effort of recycling, re-using and re: imagining the possibilities to own their our factory as well as the supply chain. The response was super positive and affirmed for us first – hand there was a HUGE opportunity to leverage trash for a more circular economy.

Why is this important?

Where do we go next?

While we left Aruba affirmed that 3D printing from waste is inherently right, we unfortunately did not secure the resources we needed to complete a prototype to leverage reclaimed plastic using Gigabot. Stayed tuned to upcoming blogs in our series as we continue to share our vision in future competitions and pursue partners to donate post-manufacturing waste streams to test. With a little luck, we will raise enough support to partner with Aruba on a pilot!

~Happy Printing!

Investment Casting with 3D Printing

The following post was written by Todd Ronan. Todd joined the re:3D sales team after hearing a Co-Founder panel discussion on 3D printing & recyclable material at IEEE. From Michigan, parts Northwest, and now Austin (Portland’s si(hip)ster city) he is a Futurist, passionate about evolving technology, dreamer, and enthusiast of fine meade.

The thousand year old lost wax casting process has been revolutionized by the Human-Scale 3D printing of Gigabot

Several re:3D customers have augmented their foundries with Gigabot 3D printers because of the time savings, cost savings, and ability to convert more jobs into happy customers.

In traditional investment casting, a wax model is dipped into a ceramic slurry which is then allowed to dry. The resulting hard ceramic shell is then heated to melt the wax away, leaving a perfect model negative where the wax used to be.

Modern foundries however, have been making the move to 3D printing as a means of creating models for casting. With the ability to use  PLA prints in place of the wax models of old, 3D printing provides a cost efficient alternative method for producing investment casting patterns.

In layman’s terms: hot melted plastic can be printed in any shape, in any size, and allows for a cost efficient alternative to the traditional technique of lost wax casting.

In the past, 3D printers lacked the size to perform life-sized pieces and large format 3D printers, starting at $100K have been cost prohibitive. Enter re:3D’s Gigabot at 1/10th the price. A 3D printer with an 8 cubic foot build space for super-sized 3D printed parts.

Anyone lucky enough to find themselves outside of Austin in Bastrop will notice the beautiful, large bronze pieces of art around the city. These are courtesy of a high-point on the Austin Cultural Map tour, Clint Howard’s Deep In The Heart Art Foundry. Jamie and Clint Howard purchased the foundry in 1999, and have become the premier statuary design and manufacturing business in the state of Texas.

With demand for large pieces the foundry added a Gigabot FDM printer to their arsenal a couple of years ago. Instead of the long curing process associated with wax models, their Gigabot can make any design using standard CAD program, and print HUGE in PLA. It just so happens that PLA burns out just as clean as wax! The cost savings was almost immediate – cutting months and thousand of dollars off traditional casting allowing for increased bandwidth for contract pieces, and substantial revenue increase. With increased demand for printing, Deep in the Heart ordered a second Gigabot printer to keep up with the demand.

Another re:3D satisfied customer: family owned and operated Firebird 3D, located in Troutdale Oregon, recently participated in the Columbia River Highway centennial celebration.  Parts on this Model A (shown below) were Gigabot printed and cast along with this Rip Caswell piece, Devoted Passion, a re-telling of the exploration and creation of this amazingly scenic Pacific Northwest highway.

At Firebird they still use their traditional processes of wax casting but can use wax filament or PLA to print larger bronze pieces. It burns out, leaving a small amount of ash in the shell mold, which can be removed with washing. 3D printed PLA plastic burns out cleanly and is a more durable and more easily handled than a wax part. Chad Caswell (shown below) checks the layer height of their next print. They are, literally and figuratively burning through filament with a cost savings up to 70% by reducing labor!

We just got word Deep in the Heart purchased a 3rd Gigabot to help with workflow and high demand, and now has three 8 cubic foot 3d printers printing (money) while their workers sleep.

re:3D urges: Try a FREE print on us. Find out if Lost Wax (minus WAX + PLA) works for you! Please contact info@re3D.org for additional info on Gigabot 3D printers and lost wax castings!
