NEWS DESK WHAT’S NEW IN MANUFACTURING n It’s Here: The World’s First 3D-Printed Jet Engine R


esearchers in Australia, led by a team at Monash University, have created the world’s fi rst 3D-printed jet engine using selective laser melting (SLM). The ongoing project, which is still in an early phase, and the information it develops, could eventually lead to wider adoption of additive manufacturing technologies to reduce weight, waste and time to market in aerospace and other industries. One of the two 3D–printed jet engines created by the team was on display at the Avalon Interna- tional Airshow in Australia, where it was unveiled to the media on Feb. 26. The other is housed at the headquarters of French aerospace company Mi- croturbo, in Toulouse, which provided the 40-year- old gas turbine engine that served as the model for the project. Prof. Xinhua Wu, a professor of materials engineering at Monash University in Melbourne and director of the Monash Centre for Addi- tive Manufacturing (MCAM), led the team. In all, that included other researchers from Monash; the Com- monwealth Scientifi c and Industrial Research Organization (CSRIO), which is Australian’s national science agency; and Deakin University, located in Geelong.

Wu, a professor of materials engineering and director of the Monash Centre for Additive Manufacturing (MCAM), led the team that has 3D printed the world’s fi rst jet engine.


A Powerful Object Wu, who has worked in the aerospace industry for 25 years and has extensively studied Ti and TiAl alloys, as well as Ti and Ni alloy powders, said she fi rst had the idea to print a complete jet engine over a year ago.


of the components were printed in a variety of materials, including nickel, aluminum and titanium alloys. MCAM has a Concept Laser XLine, which is the largest laser powder bed machine available, with a build envelope of 630 × 400 × 500 mm; two EOS INT 280M laser powder bed machines; and a Trumpf 7040 Laser Cell Blown Powder facil- ity that can house parts up to 4000 × 1500 × 750 mm. Wu noted that printing the digital fi les of the scanned components is “not as simple” as some people may think. “There are a lot of details and materials issues.”


“If we just replicated the parts, there isn’t any issue, but once you change parts, what’s going to happen?”


“I’ve been in aerospace a long time. I thought we’ve been making all sorts of [3D printed] parts,” said Wu, who has worked for Rolls-Royce, the European Space Agency, Airbus and Bom- bardier. “It wasn’t too far off to make a whole jet engine.” Wu applied for funding for the project, and Microturbo agreed to provide the older model engine, a Saphir 4-2


The complex project, which was supported by funding


from the Science and Industry Endowment Fund (SIEF) and others, took a year. While Wu said the resulting replica jet engine is a “power- ful object,” this project’s ultimate objectives are more ambi- tious than printing an old engine.
