The glow in the dark green Recyclable ABS Plastic Cube Cartridge from 3D Systems is compatible with the 2nd generation Cube printer. Each cartridge contains enough material to make about 35 models per cartridge. Switching the cartridge out is a breeze - it snaps right in. The Cube also notifies you of how much material is left in the cartridge and doesn't let you start to print a creation if you don't have enough material to finish it, avoiding waste. Up to 13 to 15 cell phone cases (or creations of similar size) can be printed from a single cartridge. An average smartphone case takes about 2 hours to print with a layer thickness of 200 microns.
You can use one color at a time while printing on a Cube. If you want your creation to be multicolored, you can either print it in separate pieces and attach them together later, or they can be printed on a different machine with an optional Cloud Printing service. The cartridges cannot be swapped in the middle of a print.
