PRINTER SETTINGS We recommend a layer height of 0.1 to 0.3 mm on FDM printers. All parts are aligned to the printing platform for easy manipulation. Most of the parts need minimal or no use of printing supports to save printing time and filament. For reliable printing, we also recommend setting a brim to the parts, because of their height and low thickness. It will ensure, that the parts will not come off the printing platform during the printing process. Printing settings will vary greatly depending on your specific printer.
