The 3D printed parts of this lamp are made from PLA filament. PLA is a non-toxic and biodegradable polymer produced from renewable sources. The PLA used in this product comes from Natureworks and is made into filament by the talented artists/engineers at Proto-Pasta in Vancouver, Washington, USA. The color is created by a small amount of automotive pearlescent pigment, with the except of the Carbon black which gets its color and texture from a small amount of carbon fiber strands.
