To clarify, this is for printing coins. The process is you buy substrate dust, and use a laser to melt the coin layer by layer out of the dust.
It would be far cheaper to use a die, for example, for large volumes. Benefit of printing is it looks slick as no matter what the design is, whereas a die has limitations on the models.
this is why i'm a fan of brass cnc or gold plated steel for this set of coins which must be completed and ready to ship by August 17th
