The two engines, created by Monash University and its spinoff Amaero Engineering, are garnering a lot of attention from leading aeronautics companies, including Airbus, Boeing and defense contractor Raytheon, which are lining up at the Monash Centre for Additive Manufacturing in Melbourne to develop new components with 3D printing.

"Australia's manufacturing industries need access to the latest technologies to stay competitive," Professor Ian Smith, Monash University's vice provost for Research and Research Infrastructure, stated in a news release. "This Centre allows them to rapidly prototype metal devices across a wide range of industries. It's part of a large integrated suite of facilities for research and industry at Monash."
One of the proof-of-concept jet engines was on display this week at the International Air Show in Avalon, Victoria. The second is being displayed at the French aerospace company Microturbo, which originally challenged the university two years ago to build the engines.
The proof of concepts are replicas of an auxiliary power unit used in aircraft such as the Falcon 20 French business jet, which was provided by Microturbo.

"The project is a spectacular proof of concept that's leading to significant contracts with aerospace companies. It was a challenge for the team and pushed the technology to new heights of success - no one has printed an entire engine commercially yet," Ben Batagol, of Amaero Engineering, stated in a press release.
The 3D-printed jet engines demonstrate that engineers can produce jet engine test parts in days instead of the months it would typically take through machine lathing and poured-mold parts processes.
The jet engines were printed using an additive manufacturing (3D printing) technique known as selective laser sintering or melting, where a high-powered laser on a robotic head melts metal powder layer by wafer-thin layer.
The engines were printed using the X-Line 1000R 3D printer from Concept Laser, a machine that Amaero calls the largest selective laser-melting (SLM) machine available. The machine is capable of sintering together metal layers anywhere from 30 to 200 microns thick.
