![]() ![]() These boast of better thermal management and resistance to the higher temperatures that these materials need. Recently new high temperature 3D printers have come on the market. Up and until now however you had to be lucky enough to have a Fortus printer from Stratasys to be able to extrude these materials coherently. ![]() ![]() We are not alone in thinking this and this makes it a material that many researchers want to experiment with. We think that these high temperature materials are the future for manufacturing using 3D printing because of their performance and ability to in some cases replace metals. Aerospace companies also are using these materials on board air craft. These materials are especially coveted in research in particular for aviation. The high abrasion resistance, high chemical resistance, low flame, self extinguishing, high strength character of these materials make them the highest performance 3D printing polymers in the market. High temperature materials such as PEEK, PEI and PPSU bring unheard of performance to desktop 3D printers. PEI needs a temperature around 340 - 360☌. PEEK needs a nozzle temperature of between 360 - 420☌ (although in some cases it may be closer to 450) and a bed temperature of 120 C. PPSU requires a bed temperature in excess of 140 C and a nozzle temperature of between 360 and 400 C. These engineering plastics require much higher temperatures to print properly. We ourselves have created materials such as PPSU, PEEK, PEEK CF, PEKK and PEI (Ultem). Therefore it is completely sensible that they have been made to operate at the temperatures required for those materials.Ī Lulzbot Taz repurposed as a PEEK and PEI high temperature desktop 3D printer.įor the past several years however we've seen people want to extrude Nylons and other higher temperature materials pushing the operating envelope of current desktop machines. Current generation desktop machines were conceived with filaments such as PLA and ABS in mind. Build platform temperatures are also limited to around 100 C. At even higher temperatures stepper motors will fail, as will electronics. At these temperatures prolonged use will degrade parts such as PTFE nozzle inserts or plastic parts in the build volume. South Georgia & South Sandwich Islands (GBP £)ĭesktop FDM 3D printers are usually able to extrude material up to temperatures of around 280 C. ![]()
