Although the Polaroid PlaySmart 3D printer has only one extruder,you can easily print models in multiple colors. By selecting Multi Color in Polaroid SmartPrep you can pre-set points on your model by percentage or height in mm where the printer will then automatically pause to allow you to change your filament to another color. When saving your file,the software then tells you exactly how long your print will take and how much material it will require. Using your Polaroid Precise Filament Holder & Scale you will then be able to ensure you have enough filament to print,meaning you will never run out of filament halfway through printing a model!
