We print larger products with polylactic acid filament, which is largely considered the most environmentally friendly printing option due to wide recyclability and theoretical biodegradability. We retain all the support material, failed prints, testing and calibration prints, and anything that can’t be sold for some reason. We use this scrap material to melt into molds. The true scrap percentage of our filament is less than 5%, possibly as low as 0.5% if we could accurately account for all scraps.
