The objective of this study is to devise and develop a remanufacturing process system employing metal additive manufacturing technology for mold refurbishment and surface reinforcement. Analyzed using metal powder, AISI H13 tool steel, known for its remarkable wear resistance and impact toughness, underwent examination for dissimilar material bonding characteristics within molds, followed by a comprehensive assessment of its mechanical behavior. An experimental design employing response surface analysis was used to systematically conduct experiments utilizing the central composite design (CCD) and Box-Behnken method, corresponding to response surface methodology (RSM), to optimize overall process variables and determine optimal conditions through variance analysis. Performance evaluation of the remanufacturing process was executed through wear tests, confirming a notable improvement in mechanical properties compared to the original state. The development of a remanufacturing system via a DED process with optimal conditions and a non-adherent support jig device facilitated post-processing by extending the virtual deposition area using a substrate forming a non-adherent film with brazing stop-off. We believe the proposed method is applicable for industrial mold remanufacturing by establishing an optimal process and constructing a remanufacturing system.
