One hot topic: The company igus advances the development of high-temperature filaments with self-built HT printer29/11/18
High temperatures not only create problems for many machine elements in plants but also conventional 3D printers. In order to develop new filaments for wear-resistant parts in high-temperature applications, igus has now built a high-temperature 3D printer. For the mechanical system, the igus engineers relied on heat-resistant stainless steel components of the maintenance-free drylin W linear guide and smooth-running dryspin high helix lead screws in the X, Y and Z axes. Lubrication-free liners and lead screw nuts made from the wear-resistant high-performance plastics iglidur X and iglidur C500 ensure precise adjustment of the building board, even with installation space temperatures of up to 200 degrees Celsius. "In the new 3D printer, we rely on standard components from igus, which work reliably even with the high installation space temperatures. We use a nozzle that can melt the filament at a temperature of up to 400 degrees Celsius," explains Tom Krause, Head of Additive Manufacturing Business Unit at igus GmbH. "Thus we were able to develop and extensively test a new filament for high-temperature environments with iglidur J350." |
