Preferred material is PETG, or ABS. PLA is also acceptable as an option. Recommended settings for a 0.4 nozzle are as follows: Nozzle diameter is 0.4mm. Extrusion width should be set to 0.5mm. Layer height of 0.3mm produces the best results. Shells should be set at 3, which results in a wall thickness of 1.5mm. Infill should be set to 20%, and infill type should be grid for optimal print quality. Solid bottom layers are recommended to be set at 3, resulting in a bottom layer thickness of 0.9mm. For the top layers, solid settings between 3 and 4 are ideal, producing a top layer thickness ranging from 0.9mm to 1.2mm.
