Abstract: The invention relates to a nozzle containing at least one static mixing element, wherein the nozzle and the at least one static mixing element are produced as a single- component object by a selective laser melting (SLM) process. The invention further relates to a process for producing a three-dimensional green body by a fused filament 0fabrication process employing at least one filament and a three-dimensional extrusion printer (3D printer). The three-dimensional extrusion printer contains the at least one nozzle containing the at least one static mixing element. The invention also further relates to a 3D extrusion printer containing the nozzle containing the at least one static mixing element.

Abstract: The invention relates to a process for producing a three-dimensional green body by a fused filament fabrication process employing at least one filament, which comprises a core material (CM) coated with a layer of a shell material (SM), and a three- dimensional extrusion printer (3D printer). The three-dimensional extrusion printer 0contains at least one nozzle and at least one mixing element. The invention further relates to three-dimensional objects and an extruded strand obtained by the process.
