Laser technology and 3D printing are key technologies for manufacturing sustainable aircraft. “With technology and know-how from Trumpf, the aviation industry will be able to put electric-powered airplanes and air cabs in the air in the near future. We can support the aviation industry with our years of battery and e-mobility expertise in automotive manufacturing,” says Richard Bannmüller, CEO of Trumpf Laser- und Systemtechnik. The company will present its manufacturing technology for the aerospace industry at the leading trade show, the Paris Air Show.

Almost all aircraft manufacturers and suppliers are working on climate-friendly aircraft. Many are already pursuing concrete concepts for the electrification of aircraft engines. For aviation, manufacturers need to develop particularly lightweight, safe and reliable batteries and electric motors. “Our experience in manufacturing electric drives and batteries in the automotive industry can be transferred to many areas of aviation. With our manufacturing technology, we can make an important contribution to the decarbonization of aviation,” says Bannmüller.

The company works with many OEMs and suppliers in the aerospace industry. To manufacture particularly efficient rockets and thrusters, the companies use lasers from the high-tech company to cut and weld metal alloys. To make engines lighter and more efficient, the aerospace industry uses 3D printers from Trumpf. As a result, manufacturers are producing lightweight thrusters that are also particularly optimized for efficiency. The product life cycles in the aerospace industry are very long. That is why Trumpf supports its customers for many years with service and spare parts for their machines.

Repairing instead of buying new: Repair with laser buildup welding

The aviation industry also benefits from Trumpf technology when it comes to maintenance. For example, instead of purchasing new engine blades, aviation companies repair them using laser cladding (LMD). In this process, the laser creates a molten pool on the surface of the engine blade and precisely melts the simultaneously fed metal powder according to the desired shape. By repairing cost-intensive components, the aerospace industry can save up to 80 percent in costs compared to purchasing new ones.
