Selective Inhibition Sintering (SIS) has been proven effective in producing polymeric and
metallic parts. Due to the low cost and high quality of SIS printing, the impact of SIS printing in
the 3D printing industry could be disruptive. The potential of SIS is further extended to ceramics,
an important but hard to print material, by the same mechanism of creating an easy-to-break
sacrificial mold. Due to the high sintering temperature of ceramics, fluid based inhibitors
delivered by inkjet printing tend to not be effective in SIS for ceramics. Accordingly, the new
concept of inhibition by dry powder delivery is implemented. Preliminary experiments have
shown the feasibility and ease of printing of simple ceramic parts. Additional experiments are
underway to increase the possible part complexity and accuracy, and to optimize the sintering process.Mechanical Engineerin
