no mention of the different types of filaments that can be used
exactly, PLA is supposed to be biodegradable and doesn't smell when you make things with it. I bought a spool of PLA because it was relatively inexpensive to test out a 3D printer I just got. if I want to make anything more "final" I'll use ABS but the PLA does very well for testing designs, especially if you're likely to throw it away after you screw it up for the N'th time.
