PTC will showcase the world’s first fully 3D-printed jet engine at its LiveWorx 2023 premier event, beginning Monday, May 15, in Boston, Massachusetts. The micro turbojet engine, weighing approximately eight pounds and printed with Inconel, is a single, complete assembly, including all rotating and stationary components, and was designed in our Creo CAD software.
Designing and printing a fully self-supported micro turbojet engine, including the 50,000 RPM turbine, that requires no assembly, represents a significant breakthrough in designing for additive manufacturing. After all, a jet engine is one of the most powerful and complex things out there, between the performance requirements for operation and the intricacy of the components – many of which rotate or move in some way. But we’ve spent the last several years advancing our core design capabilities in Creo and the ability to transfer sophisticated designs directly to a 3D printing environment.
This proof point for additive manufacturing could have material impacts on the aerospace industry and how we think about manufacturing these kinds of micro turbojet engines. Today, these engines require complex assembly processes of many expensive parts, which puts customers directly in the crosshairs of supply chain dependencies, limited availability, and their manufacturers maintaining the right employee expertise to complete assemblies. With additive manufacturing, there is no assembly process, and there’s potential to substantially reduce the number of components used and tooling required for production. This brings down costs, reduces requirements down to a metal 3D printer, and opens the possibility of on-demand manufacturing directly at the customer site.
The jet engine project was conceived by Dr. Ronen Ben Horin, a VP of Technology at PTC and a Senior Research Fellow at Technion – Israel Institute of Technology and Beni Cukurel, an Associate Professor of Aerospace at Technion. The two brought together many years of deep scientific research in jet propulsion and engineering expertise in the design of advanced engines and designing for additive manufacturing.
When we spoke with Beni about the achievement, he acknowledged that it’s a rewarding accomplishment for him and Ronen, a culmination of many years of research while staying on top of advancements in the supporting technology. He’s pleased to see that their extensive knowledge and experience in jet propulsion could now result in a commercially viable way of producing these kinds of micro turbojet engines. He also credited Creo for being a powerful engineering system that’s capable of supporting their vision and this level of innovation.
Many of the Creo advanced design capabilities were used for the jet engine assembly, including:
After LiveWorx, we’re taking our assembly on the road to the Paris Air Show from June 19-25.PTC, LiveWorx, Creo and the PTC logo are trademarks or registered trademarks of PTC Inc. and/or its subsidiaries in the United States and other countries.
