Abstract
Traditionally molds for metal injection molding (MIM) process are made through conventional machining techniques. However, if the MIM parts are customized, and demand is in low-volume or the design changes are frequent, the machining of mold could be expensive and time-consuming. Fused deposition modeling (FDM) is a promising process to manufacture molds for prototyping or low-volume MIM part production. For mass production, FDM-made molds could still be feasible for production of MIM parts for analyses, validation, and other upstream processes, ahead of permanent mold making. Apparently, sustainable production of moderately low or medium volume demands of MIM parts through FDM manufactured polymer molds could seem challenging. However, recent studies have reported some enhancements techniques, which could be promising to augment the MIM performance of the FDM-made polymer molds. The chapter critically analyses the significance of enhancements in processing parameters, surface and build material for improvement in performance of polymer molds for MIM process.
