But an older technology called binder printing has been improved to produce durable metal parts faster than laser sintering can. Car parts have usually been made by laser “sintering,” which fuses layers of powder together. One such breakthrough is a change in the printing process. ![]() “There are breakthrough developments in additive manufacturing,” Goede said. Volkswagen has planned to introduce 3D printing gradually, starting with customised trim parts and progressing to chassis parts on production cars by 2023, before an original estimate. “Otherwise there is no reason to do this.” “If you include the tooling or casting, you are actually going to have better economics now,” he said. He said his printers had brought part costs below those for traditional manufacturing. He said that Divergent had printed chassis parts that are being crash-tested by two top global car manufacturers and will print 1000 suspensions this year for use in a production car, which he declined to name. “That rate in the next few years will double again,” he said.Ĭzinger said he sped up printing partly by optimising the process for a limited number of aluminum alloys. Though the company plans to produce 80 cars this year, the 21C is primarily a demonstration of founder Kevin Czinger’s 3D printing process, which he claims is 10 to 20 times faster than other printers.
