German machine tool manufacturer TRUMPF is demonstrating the applications of additive manufacturing for satellites and aircraft at the 2019 International Paris Air Show.
With the company’s expertise in Laser Metal Fusion (LMF) and Laser Metal Deposition (LMD) technology, weight reduction, cost efficiency, and part optimization are presented for the aerospace industry. Thomas Fehn, General Manager Sales, Market & Finance for TRUMPF additive manufacturing, said:
MARKET - SHARE - OF - OVER - %
“WITH A MARKET SHARE OF OVER 20%, THE AEROSPACE SECTOR IS ONE OF THE WORLD’S MOST IMPORTANT INDUSTRIAL USERS OF ADDITIVE MANUFACTURING. WE ARE STEADILY EXPANDING OUR MARKET SHARE AND HELPING TO ESTABLISH THE PROCESS AS A KEY TECHNOLOGY.”

Aerospace and additive manufacturing
According to TRUMPF, LMF technology is suitable for creating complex parts for engines, combustion chambers, and specialist aerospace components. This process builds up a part layer by layer from a powder bed. On the other hand, LMD uses a laser beam to build up layers on the surface of a part with metal powder being extruded through a nozzle.
Process - Parts - Prototype - Development - Repairs
This process can be used to rapidly generate very large parts for prototype development and repairs to large parts including gas turbines and compressor blades. Fehn added, “Thanks to our LMD and LMF capabilities, we are perfectly placed to offer our aerospace customers 3D printing solutions that match their needs.”

A lightweight satellite
Among TRUMPF’s use cases is a 3D printed mounting structure commissioned by German Aerospace company TESAT for the Heinrich Hertz communications satellite. This mounting structure integrates strap-on motors which modulate microwave filters.
Collaboration - AMendate - TRUMPF - Topology - Mounting
With collaboration from AMendate, TRUMPF engineers optimized the topology of the mounting structure and reduced its weight from 164 grams to 75...
