The Cube prints in solid color ABS, with one color per cartridge. ABS (Acrylonitrile butadiene styrene) is considered the second easiest material to work with when you start 3D printing. The same kid-safe material that Legos are made of, ABS is also a strong and tough engineering polymer commonly used to produce car bumpers. Though durable, considerations must be made when printing larger objects as thermal stress can cause ABS to warp as the part cools. ABS is suitable for light, rigid, molded products with good shock absorption and wear resistance.
