What's the difference between ABS and PLA?
Acrylonitrile Butadiene Styrene (ABS) is lightweight and it has a lower coefficient of friction. That makes it preferred material for small parts, compared to PLA. ABS has to be extruded at a higher temperature. Its glass transition temperature is around 105°C/220F. ABS is amorphous and therefore has no true melting point, however 230°C/445F is the standard for 3D printing. Most LEGO is made of ABS.
Polylactic acid (PLA) is a bio-degradable polymer derived from corn starch. It is melts at a lower temperature around 180°C/355F, and a glass transition temperature around 60°C/140F. It does exhibit higher friction which can make it difficult to extrude. PLA will flow more easily than ABS at the same temperatures and usually more glossy.
