Biodegradable 3D printer filaments make up a unique category, as their most valuable characteristic does not lie in their physical natures. As most hobbyists can attest to, not every print turns out the way you want it to, and this results in having to throw away a ton of plastic. Biodegradable filaments seek to negate the environmental impact this has on our planet.
As was mentioned earlier in this article, PLA is in fact a biodegradable filament, but others include twoBEars’ bioFila line and Biome3D, by Biome Bioplastics.
When Should I Use Biodegradable 3D Printer Filament?
Regardless of their primary reason for existing, biodegradable 3D printer filament types often produce items of sound physical quality. Use them any time you don’t have specific requirements for strength, flexibility, or endurance. And if you really want to take advantage of the guilt-free printing biodegradable filaments offer, try using them in projects which require prototyping.
