摘要: A fused deposition modelling method for producing multicoloured three-dimensional objects, in particular a 3D printing method with which 3D objects can be produced with a particularly good colour image in comparison with the prior art. The method is based on the concept that the polymer strand (2), or the resultant melt, that is used for producing the actual object is superficially coloured or coated with additives in the nozzle (1).

摘要: The invention relates to modified extrusion-based 3D printing, in particular a modified Fused Deposition Modelling process, for producing multicoloured three-dimensional objects. In particular, the invention relates to a 3D printing process with which mechanically stable, multicoloured 3D objects can be produced with a particularly good colour image in comparison with the prior art. The process according to the invention is based on the concept that the polymer strand that is used for producing the actual object is coated before the print head and the coating is fixed before the polymer strand enters the print head. After the extrusion in the print head, the coating is largely still on the surface of the extruded strand. The coating may be coloured or contain functional additives.
