The invention provides a method for manufacturing a 3D item (10), wherein the 3D item (10) comprises an outer layer (210) and a support structure (220) with cavities (230), wherein the outer layer (210) at least partly encloses the support structure (220), and wherein the method comprises: (a) a 3D printing stage comprising 3D printing with fused deposition modeling (FDM) 3D printable material (201) the outer layer (210) and the support structure (220) and at least partly filling the cavities (230) with a filler material (204); and (b) a post-treatment stage comprising post treating at least part of the outer layer (210) for reducing surface roughness.
A method for manufacturing a 3D item, wherein the 3D item comprises an outer layer and a support structure with cavities, wherein the outer layer at least partly encloses the support structure, and wherein the method comprises:
A fused deposition modeling 3D printer comprising a printer nozzle and a filler material dosing unit, wherein the 3D printer is configured to provide a 3D item comprising an outer layer and a support structure with cavities, wherein the outer layer at least partly encloses the support structure, and wherein the cavities are at least partly filled with filler material, wherein the 3D printer further comprises a post-treatment stage unit configured to post treat at least part of the outer layer of the 3D item for reducing surface roughness.
