Polylactic Acid (PLA) is a plastic extract from starch (commonly from corn) which is low environmental impact. It is a derivative of starch, green and renewable, a biodegradable material (degrade by itself in the soil), which is environmentally friendly.

Rapid Fusion 3D high performance PLA filament is based on FFF/ FDM technology, with a commonly used diameter of 1.75 mm, 190-220oC printing temperature,50 oC bed temperature (May not necessary) , having excellent interlayer adhesion which greatly improve the strength and shock resistance of the prototype.

PLA can print large models without a heating platform and warping will not happen easily. iT has a low shrinkage rate and performs well even when printing large- size models. PLA is widely used in education, home, machinery, electronic appliances, instrumentation, and other fields/
