The purple Cube 3 PLA Filament Cartridge from 3D Systems is made to fit the Cube 3 Printer and contains enough filament to produce approximately 13 - 15 cell phone cases.
Cube 3 cartridges are designed to snap into the Cube for easy loading and switching. The smart cartridge can tell you how much material you have left, and it won't let you start a print if you don't have enough material to finish it. Moisture-lock construction protects your filament from water and environmental damage.
Objects printed with Cube 3 PLA filament can even be dishwasher-safe if made thick enough.
