Abstract

The invention relates to a modified fused deposition modeling process for production of multicolored three-dimensional objects. More particularly, the invention relates to a 3D printing process with which 3D objects with particularly good color appearance compared to the prior art can be produced. The process according to the invention is based on coloring of the polymer strand used for production of the actual object in the nozzle, and on using a mixing apparatus which comprises a plurality of injection needles, a static mixer or a dynamic mixer.
