Abstract:
Cetim has launched further material project development on binder technologies. This work deals with the development of the tool steel X40CrMoV5-1 or H13 on two Metal Binder Jetting technologies, namely DM P2500 (Digital Metal) and Lab P-1 (Desktop Metal). The whole MBJ H13 has been developed by adjusting the 17-4PH powder printing parameters and by developing a specific sintering recipe by using a vacuum metallic furnace under controlled atmosphere (one step debinding sintering). The presentation will be focused on sintering development. Controlling the final carbon content and achieving high density level without excessive component distortion by using SLPS process are the main challenges to overcome. The microstructure and the mechanical properties are compared. For both technologies, as sintered mechanical properties are consistent with data coming from MIM H13 materials and wrought materials.
