This 3D printer prints reliably and precisely. This is thanks to the lubricant- and maintenance- free plastic components from igus®. The device uses drylin® guide rails, iglidur® bushes and igubal® rod end bearings. Conventional metal products would have corrosion-related problems in the high- acid environment inside the printer. In addition, the lubricant would soil the printed product. By the way, the printing medium used is iglidur® Tribo-Filament from igus®.
