Endless PETG #1 (March 2022) - High Five Blue and Carbon Fiber PETG
What do Milk Duds and Protopasta PETG have in common? A high five to anyone who guessed it! We hope you enjoy Joel’s favorite sweet treat, Milk Duds, while printing with High Five Blue PETG. What’s not to love about this blue though, really? Do you remember when we first designed it together with Joel? What a special experience!
It’s funny how things come full circle. Joel’s back on Etsy (be sure to check out his store), and we’re back to more High Five Blue (and Carbon Fiber too, but more on that in a bit). We’re grateful to Joel for all he’s shared, inspired, and encouraged over the years. If not for him, not only would High Five Blue not exist, but you might not know about us. Thank you Joel and good luck as you expand to platforms like TikTok (be sure to follow @joeltelling5).
Joel has been a fantastic ambassador on behalf of the Protopasta and the greater 3D printing community. We all owe him a lot for his integrity, positivity, and dedication. He may be the hardest working individual in 3D printing. I say that, but there are so many fantastic hard working makers and creators. We appreciate you all!
In fact, there is nothing more rewarding than supporting other makers, especially those that, like us, made the leap to a business based on 3D printing. It can be intimidating to have other businesses rely on you, but being there for another business to support their product with our own… well, it really doesn’t get more rewarding!
This is exactly what happened in the case of Carbon Fiber PETG. In these constrained times, we’ve actually been working on supply and formulation of PETG for basically the entire pandemic. We weren’t ready to commit to release with these in flux, but behind the scenes, we found an opportunity to support Negative Supply.
We connected with Saxon McClamma of Negative Supply, who was working to replace HP Fusion Jet parts made from sintered nylon. He chose Matte Fiber HTPLA for it’s stability and strength. He loved the layer-hiding, low light reflection surface, but wanted something with a bit more flex and temperature resistance without heat treating. We shared a sample of the Carbon Fiber PETG we had in development, and he was hooked.
The amount of material Negative Supply has consumed, and in replacement of 3d printed nylon, is impressive. Even though Protopasta Carbon Fiber PETG is new, it’s been tested and proven by Negative Supply in multiple applications over the last couple years. They often use the parts as-printed, but sometimes wrap surfaces (especially top and bottom) with Tolex vinyl to further improve aesthetics. The 3D printed part’s texture and fibers help with adhesion.
Protopasta Carbon Fiber PETG has become Negative Supply’s go-to general-purpose engineering material! Why? Because it prints so easily and reliably while performing so well. And when they're done, the cardboard spools are recycled locally for reduced environmental impact, reinforcing a commitment to only put long-standing material where long-standing material is meant to be!
We’re so excited for this collaboration with Negative Supply. Thank you Saxon! For more about Negative Supply read below or visit their website, Negative.Supply. When at their website, look closely and you’ll notice 3D printed Carbon Fiber PETG in most of their products.
About Negative Supply:
Negative Supply exists to create tools for film photographers around the world that want to spend more time photographing, and less time scanning. Their first product, the Film Carrier MK1, allows digitization of negatives and positives using a digital camera and macro lens in as little as 5 minutes with readily available tools. Available now.
Using agile manufacturing techniques at their California design studio and assembly workshop, Negative Supply is able to create tools for working photographers and archivists not available elsewhere. They believe in doing everything they can in house.
