Sinter-based AM technologies are rapidly emerging and gaining interest among manufacturers due to the potential for lower cost and higher throughout with broader materials application compared to fusion-based AM technologies. Sinter-based AM processes are available across four of the seven ISO/ASTM standard AM categories, including Binder Jetting (BJT), Material Extrusion (MEX), Material Jetting (MJT) and Vat Photopolymerization (VPP) technologies. Unique in these processes, powder material is bound together with a binding agent in the feedstock or during the printing process, producing what is commonly referred to as a “green” or “brown” printed part. Secondary debinding and sintering steps are required to remove the binding agent and consolidate the powder material to the desired final density. Considerable knowledge is necessary to properly design and control the debinding and sintering process steps which are critical to achieving the desired material properties and final part quality requirements. In this webinar you will learn the basics including the kinetics of debinding and sintering, types of furnaces and the effect of process atmospheres, and general guidelines for densifying bound powder parts.
