PTC
First 3D-printed jet engine
PTC introduces the world's first fully 3D printed micro turbojet engine. It is a single, complete assembly, including all rotating and fixed components. The engine weighs only 3.6 kg.
According to PTC, the development and 3D printing of a fully self-supporting micro turbo engine including a turbine with 50,000 revolutions per minute that requires no assembly marks a breakthrough in design for additive manufacturing. Until now, complex assembly processes and many, often expensive components have been required for such engines. This poses challenges for manufacturers in terms of the supply chain and the availability of parts. They must also ensure that they keep the expertise and skills required to manufacture these high-precision assemblies in-house. Additive manufacturing also eliminates the need for components and tools along with the assembly process. This reduces costs and enables on-demand production directly at the customer's site.
The fully 3D-printed engine is the result of a project conceived and led by Dr. Ronen Ben Horin, VP of Technology at PTC and Senior Research Fellow at the Technion - Israel Institute of Technology, and Beni Cukurel, Associate Professor of Aerospace at the Technion. It required years of intensive scientific research in the field of jet propulsion and extensive expertise in innovative engine technology and design for additive manufacturing.
The thruster was designed in PTC 's Creo CAD software and printed on an EOS 3D printer.
