Combination of LPBF and welding: A practical application Manufacturing of the epee for Dominique Perrault [PDF]

, 2023
One of the limiting factors of the actual LPBF machines is the size of their build chamber, their productivity, and the process stability. The welding of LPBF parts can be used to overcome these problems, but at the moment it is mostly shown on ...
