Our PLA filament is a 1-kg. reel of filament for use with fused filament 3D printers (sold separately). Polylactic acid (PLA) is a biodegradable, plant-based plastic that offers a smooth finish on printed parts. It can be used with a heated bed set to around 60 degrees C (140 degrees F) to prevent warping during the printing process and facilitate removal. Store any open unused product in a cool dry place. This material absorbs moisture. The print temperature ranges from 180 to 240 degrees C (356 to 464 degrees F).
