Compared to the traditional manufacturing method such as casting or forging, some are concerned about the strength metal 3D printer can realize. The both L-PBF and EB-PBF fuse metal powders, the solidify it very quickly, so the strength they realize is basically the same as or more than the traditional manufacturing method depending on a metal.
