A 3D extrusion print process for producing multicolored three-dimensional objects is provided. The process produces mechanically stable, multicolored 3D objects with good color definition. The process according to the invention is based on coating, upstream of the printing head, of the polymer strand used for producing the actual object, and on fixing of the coating upstream of entry of the polymer strand into the printing head. Downstream of the extrusion process in the printing head, the coating remains predominantly at the surface of the extruded strand.

Multicolour extrusion-based 3D print process

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.

The present invention provides a degradable extruded netting. The netting comprises a plurality of interconnected strands with at least some of the strands comprising a degradable composition comprising a polyolefin, a metal carboxylate, and an aliphatic poly hydroxy-carboxyl acid. In at least one embodiment, at least 10% of the strands are made of the degradable composition. The present invention also relates to a method for making degradable extruded netting. The method comprises extruding strands of polymeric material to form a netting wherein at least some of the strands are formed of the degradable composition.
