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 0 contains 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.
