Stainless-Steel Parts Produced via 3D Printing and Powder Injection Molding

Popis výsledku v původním jazyce

This study aims to compare 17-4PH stainless steel parts produced via additive manufacturing techniques such as powder bed fusion and material extrusion with well established mass production - powder injection molding (PIM). Both approaches tend to merge in the way that the prototypes are 3D-printed, and the mass production is implemented with PIM. This brings the necessity to compare the mechanical performance as well as surface properties resulting from the different process parameters. PIM parts were manufactured from both 17-4PH stainless steel PIM-quality powder and powder intended for powder bed fusion compounded with recently developed environmentally benign binder. Rheological data obtained at the relevant temperatures served to set up the process parameters of injection molding. Tensile and yield strengths as well as strain at break suggest that powder bed fusion provides the sintered samples of the highest strength and ductility. Advanced statistical analyses of the surface properties (evaluated through a 3D scanner and revealing the superior surface of parts produced with PIM) showed closest proximity between surfaces created via PIM and material extrusion.
