PLA filament is the most used 3D printer filament in the 3D printing community. PLA is easy to print contributing to its low 3d print temp and good adherence on heated bed. PLA is a bio-degrade material, it is derived from starch of corn or cassava. The 3D printed model of PLA filament is hard and strong enough for education or house gadgets. But for function parts or engineering applications, PLA is too brittle. Its temp resistance is low, so it can not apply to objects that work in a high-temperature environment.
