Affordable Metal 3D Printing – New Selective Inhibition Sintering (SIS) Process May Be Groundbreaking
Currently, machines capable of printing with various metal alloys run anywhere from $500,000 on up, making them basically untouchable to the general pubic. Those machines which are currently under development usually combine technologies such as welding with Cartesian-based movement systems of a typical FFF/FDM printer to produce objects which are pretty rough, lacking any type of precision.
This may all be about to change thanks to research being conducted on an entirely new method of metal printing called Selective Inhibition Sintering (SIS). Developed by Dr. Behrokh Khoshnevis and his team at the University of Southern California, this new method of printing is basically the inverse of selective laser sintering and other forms of metal printing.
