| description | The invention provides a method for producing a 3D item (1) by means of fused deposition modelling, the method comprising a 3D printing stage comprising layer-wise depositing an extrudate (321) from 3D printable material (201), to provide the 3D item (1) comprising 3D printed material (202), wherein the 3D item (1) comprises a plurality of layers (322) of 3D printed material (202), wherein each layer (322) has a layer height (H) and a layer width (W), wherein the 3D printing stage comprises generating a stack (1322) of the layers (322) of the 3D printed material (202), wherein at a fixed first x,y-position the layer height (H) is varied layer by layer for a subset of a total number of layers (322), wherein either (i) the layer height (H) increases for consecutive layers (322) and then the layer height (H) decreases for consecutive layers (322), or (ii) the layer height (H) decreases for consecutive layers and then the layer height (H) increases for consecutive layers (322); and wherein at least part of the 3D printable material (201) comprises light transmissive polymeric thermoplastic material (401). |
