Sounds pretty good! It’s printed out of PHA (polyhydroxyalkanoates). This is a food safe naturally occurring material synthesized by bacteria, and it is fully biodegradable in a reasonable time span, in any biome, with no microplastics. Design from SolidZone, material from Filaments.ca Regen collection. Once the world figures out how to get sustainable pinene resin working, I want to try running a vacuum resin stabilization on it as well.
Hadn’t heard of PHA before. Anything you can say about how it behaves in print?
Absolutely! It can be a teeny bit finicky compared ol’ reliable PLA, but I think it’s pretty worth it. The only real issue is that wide flat parts have a tendency to warp off the build plate? Here’s what I’ve figured out so far about making it adhere extra well:
There, that’s everything I know so far. This probably makes the warping sound a lot worse than it is. It’s really not super terrible. You probably won’t have to barely ever use any of these tips, and if you can get past the warping, every other aspect of printing with PHA works like a dream.
Thanks a lot! Think, I’ll give it a try. Does it produce a lot of fumes/smell?
No prob! None whatsoever, as far I can tell
Eyyy, someone else playing with PHA!
I have a bunch of PHA commentary (and experimentation) over on the kbin 3d-printing group:

omg yeah, your stuff has been really helpful! there’s so little info out there about it, I hope it catches on
