From food waste to carbon fiber, the wide world of 3D printer filament

Food waste

AgriDust is a material made from a blend of the most commonly found foods in landfills, like coffee grounds, peanut shells, orange and lemon peels, tomato skins, and a binder made of potato starch. The print and the excess filament can be composted after it's used since it's all biodegradable.
