Watch the time lapse video of our RepRap Industrial printing a large 3D two-color logo from magenta and black ABS plastic.
With its dual extruder print head, the RepRap Industrial is capable of dual-color, dual-material and dual-nozzle-diameter configuration. All kits come with 6 easily interchangeable nozzle tips of multiple diameters (0.25, 0.35, 0.5 and 0.75).
