A good example of igus’ low-cost automation concept is the newly designed and constructed high-temperature 3D printer. It was built using drylin W linear guides, dryspin lead screws made of stainless steel and igus standard stepper motors, to facilitate the development of iglidur J350 high-temperature filaments.
Dean Aylott, dry-tech specialist product manager, igus explains: “High temperatures not only create problems for many machine elements in plants but also conventional 3D printers. To develop new filaments for wear-resistant parts in high-temperature applications, we built our own high-temperature 3D printer.” For the mechanical system, igus engineers used the heat-resistant stainless steel components of the maintenance-free drylin W linear guide and smooth-running dryspin high-helix leadscrews in the X-, Y- and Z-axes. Lubrication-free liners and leadscrew nuts made from the wear-resistant high-performance iglidur X and iglidur C500 plastics, ensure precise adjustment of the building board, even at temperatures of up to 200degC.
Aylott explains: “We use a nozzle that can melt the filament at a temperature of up to 400degC. This enabled us to develop and extensively test a new filament for high-temperature environments with iglidur J350.” The lubrication-free iglidur J350 material is already offered as plain bearings and bar stock. Characterised, above all, by its extremely high wear resistance and its low coefficients of friction on steel, the engineering plastic has high dimensional stability at temperatures up to 180degC.
Using the HT-3D printer, the filament can be processed well on a printing plate equipped with a PET film. Typical application areas of the new iglidur J350 filament include vending machine technology, automotive, glass processing and general mechanical engineering. In addition to iglidur J350, six more filaments are available from igus: from materials approved for food contact up to chemical-grade plastics.
