Abstract: The invention relates to a method of manufacturing an object (1100) by means of 3D printing using a 3D printer (1200) with an extrusion head (1210) and a build platform (1220). The extrusion head (1210) has a nozzle (1211) with an opening (1212) through which printable material (1300) can be deposited onto a receiver item. During printing the extrusion head (1210) moves relative to the build platform (1220) along a tool path (1230) in a plane parallel to the build platform (1220) to create a layer (1110) of the object (1100). When the opening (1212) of the nozzle (1211) has a non-circular boundary with a rotational symmetry of order n (n being an integer equal to or larger than 2), the tool path (1230) should consist of two or more straight tool path segments, wherein each angle between two adjoining straight tool path segments is an integer multiple of 360/n when n is an even integer, and an integer multiple of 180/n when n is an odd integer. This method allows the manufacture of printed objects (1100) of which the layers have faceted side surfaces that may give an aesthetically appealing effect, while preventing inaccuracies in the layer structure.
