As 3D printer filament, PLA is the most used and easiest print material and great for 3D printing novices to start with. It's made from organic materials and is biodegradable, which makes it one of the more environmentally friendly thermo plastics available. In neutral form the filament is semi-translucent with a brownish color and you can print at around 200 degrees. After printing the material is more brittle than other types of filament, making it break instead of bend when pressure is applied.
