Multicolor-extruder

Overview This extruder is designed to print up to four colours or materials with only two driving motor. It consists of 4 hot-ends, one of the stepper motors used to switch between hot-ends while printing. Each hot-end may have a specified task assigned, one for infill (larger nozzle size), one for support material (PVA), and two smaller sized nozzles for two colour printing of outer layers. Later testing also can be done for electric conductive materials and materials with elasticity. The possibility of 3D printing can be limitless with all those different materials and an extruder that is able to use and cooperate them in a single print.
