Multi-material 3D-printing laser powder bed fusion goes beyond welding in blending low-carbon stainless steel and bronze

https://techxplore.com/news/2025-04-welding-3d-complex-metals.html

"multiple powdered metals deposited with micron-level resolution, laser melted together in 1 layer during additive deposition... 1 cm tall metal part includes 1.000s metal powder layers, few hours to print... address pores/ cracks in real time viewing digital 3D rendering through CT scans... finished structure complex gyroid shape (when multi-material can only be created using this method), used in applications such as heat exchangers/ biomedical implants... future: use with other types of metal powders"
