Polystyrene Cups
| That'd be a cool form of recycling, ngl.
| i mean, couldn't you just melt them and pour them through a funnel of appropriate nozzle size?
| I researched this a bit more, and it seems as if filament extruders use grainlike pellets in filament extrusion. So I think you could probably just cut the cups into very small pieces, and it might work.
| Well are we sure the cups are 100% polystyrene though? There might be other materials mixed in that might damage the printer.
| Well looking at the 6 on the bottom of the cup it should be close to 100% polystyrene. Some cups have whitish dyes, but that shouldn't matter too much.

| I was wondering if you could just take a bunch of the free Polystyrene water cups at fastfood chains and convert them into polystyrene filament for use in 3d printing somehow. I know you need pellets for filament extruders, but you can simply just make a mold about the size of a pellet and melt them into the mold, thus making a polystyrene pellet, right?
