Monoprice 15835 3D printing material Polylactic acid (PLA) White 2.2 lbs (1 kg)

PLA is a good choice for a printing material if you are looking for high accuracy and high resolution. It extrudes at lower temperatures, does not require a heated base, and has a very low shrinkage rate (0.3%). PLA is harder than ABS, but is therefore also a bit more brittle. Additionally, PLA is a plant-based plastic, which means that it is biodegradable and gives off a slightly sweet odor, like roasting corn.
