Laser powder bed fusion at the end of the production process. In this process, metal powder is fused using a high-performance laser in a layer-by-layer build-up process.
In powder-bed-based additive manufacturing, metallic materials solidify under extreme temperature gradients and high cooling rates. In addition, during the layer-by-layer process, previously solidified material is reheated, resulting in complex temperature distributions within the component. Materials originally developed for conventional manufacturing processes often face limitations here and can be challenging to process additively. Therefore, further development and innovation in alloy design for powder-bed-based additive manufacturing are essential to improve processability and optimize material properties.
