There are different plastics you can use, but the two most common are ABS and PLA (bio plastic). The feed plastic just has to come in the right filament size, and have a melt temp within reach of the hotend/extruder (200-275C). Some plastics might need a vent hood or closed print cabinet, as they can off gas some nasty by products. My printer feeds 1.75mm diameter filament, and I only have ABS on hand at the moment.
