I never imagined that this would be possible.”īut to make this dream a reality requires more than new machines, says Morris, who sold his business to GE and now works with Ehteshami. “But additive allows you to get sophisticated and reduces costs at the same time. “In the design of jet engines, complexity used to be expensive,” Ehteshami says. Morris combined all 20 parts into a single unit that weighed 25 percent less than its predecessors and was more than five times as durable. We caught up with Morris at the GE Additive pavilion at the Paris Air Show in June. I knew that we found a solution, but I also saw that this technology could eliminate what we’ve done for years and years and put a lot of pressure on our financial model.” “I remember that day like today,” Ehteshami told GE Reports. He printed it from a nickel alloy and invited the team over a few days later. When Morris agreed to help, the GE engineers sent him a secret computer file with the drawing of the intricate nozzle tip. “We tried to cast it eight times, and we failed every time,” recalls Mohammad Ehteshami, who now runs GE Additive, a new GE business dedicated to supplying 3D printers, materials and engineering consulting services. It had more than 20 parts that had to be welded and brazed together. At the time, they were developing an efficient fuel nozzle for a new jet engine, but the design was so complex they had trouble producing it. This was propitious timing for engineers at GE Aviation, which is based in Cincinnati’s northern suburb of Evendale. His company, Morris Technologies, was based in Cincinnati, and by 2003, word about his project had spread around town. He would go on to launch what we now call additive manufacturing. The machine was useful for rapid prototyping, but he also saw the technology's potential for mass production. He acquired an early 3D printer for metals that used a laser beam to fuse together fine layers of metal powder. That machine allowed Morris to print polymer parts layer by layer directly from a drawing inside a computer.Īfter his first taste for this emerging technology, Morris wanted more. The entrepreneur bought his first stereolithography machine back in 1994, when 3D printers were still largely confined to university labs and research centers. Few people know more about 3D printing than Greg Morris.
