ABS
Material
Acrylonitrile butadiene styrene (ABS) is a terpolymer made by polymerizing styrene and acrylonitrile in the presence of polybutadiene. The most important mechanical properties of ABS are impact resistance and toughness. A variety of modifications can be made to improve impact resistance, toughness, and heat resistance. Lego bricks are made from ABS
PLA
Material
Polylactic acid, or polylactide (PLA) is a thermoplastic polyester. It is one of the most common 3D printing materials due to printing simplicity. It is stronger than ABS but not as durable. It also has a lower glass transition temperature than ABS making it less suitable for high temp applications. PLA is biodegradable therefore product like plastic bottles are manufactured from PLA.
