Metal 3D printing is a work-in-progress as R&D continues. Current 3D printers that can use metal alloys typically have a starting price of around $500,000, which severely limits their use. Furthermore, their printed products are imprecise and tend to be pretty rough. Dr. Behrokh Khoshnevis and his team out of the University of Southern California are researching a totally new, unique method that just might turn lower-cost 3D metal printing into a reality. Their new method, Selective Inhibition Sintering (SIS), is effectively the inverse of selective laser sintering (SLS) and other forms of metal printing, and seems to be a very promising new technique.

Is this the path to affordable metal printing from the desktop? Let's hear your thoughts! Below is a photo of the SIS 3D printer:
