Large-scale 3D printing via gantry-based Laser Powder Bed Fusion at Fraunhofer ILT

With development of the gantry-based multi-scanner LPBF machine "LPBF SkalAr", new standards for scaling laser powder bed fusion (LPBF) have been set at the Fraunhofer Institute for Laser Technology. The machine allows processing with five independent laser-scanner units on a build volume of 1000 x 800 x 350 mm³, making it one of the largest LPBF machines worldwide. As seen in the video, the machine is now qualified not only for 316L stainless steel but also for processing the highly relevant nickel-based superalloy Ni718.
