Smartfil Oyster is a high quality biodegradable and compostable 3D printing filament, obtained with a base of thermoplastic material and a load from the reuse of organic waste such as crushed oyster shell. We have developed a filament, which also favors the circular economy and improves environmental quality. Due to the nature of the filaments from organic waste, the color tone can vary on the spools or between batches.
