Polymaker - PolyTerra PLA - Ice - 1.75mm PolyTerra PLA is a new type of bioplastic 3D printing filament, which is not only harder than conventional PLA, but also has less impact on the environment. By reducing the amount of raw PLA and adding organic materials, the amount of plastic in the material has been reduced by about 40%. The blended organic materials give PolyTerra PLA a matte finish. Further, Polymaker, the manufacturer of PolyTerra PLA, has partnered with the non-profit organization One Tree Planted to plant a tree for every spool sold, further emphasizing the environmentally friendly aspect of PolyTerra PLA.
