PLA filaments are extracted from biodegradable materials. In addition to being environmentally friendly, PLA filaments also print in low tempratures which greatly reduce the warpage. The translucent texture & finishing will also add a unique look to your finished work. PLA filaments are made with polymerized lactic acid, which is extracted from corn, sugarcane or other sugar-containing crops, & is regarded as the most environmentally friendly 3D printing material. Unwanted PLA printed objects can be simply discarded in the soil where it will naturally decompose.
