Since the mid-1980s, Selective Laser Sintering has been utilized as a prominent additive manufacturing technology to meet the needs associated with obtaining 3D parts. However, as the search for faster printed parts with higher resolution increased, an alternative cost-efficient process was desired to meet such demands. With all in mind, Behrokh Khoshnevis invented the Selective Inhibition Sintering process for metals.
