... main types of metal AM processes: powder-bed fusion (PBF) and directed-energy deposition (DED). These two types of metal AM technology are fusion-based processes with similarities to fusion welding ( Ref 9 ) or, in some cases, a cross between welding and cast product ( Ref 10 ). The metallurgical...
