Desktop metal's 3d printers aren't cheap, but they're cheaper than the alternatives
Printing ready-to-use metal objects at your desk is the dream for many engineers and tinkerers. Unfortunately, we're not there yet, but these new Desktop Metal printers, as seen on TechCrunch, get us a lot closer. The Studio Printer is a $49,900 machine that prints metal layer by layer in a way similar to that of a traditional plastic 3D printer, instead of the subtractive method that's more common with metal "printers." Then the plastic binder is removed (by a $9,900 machine) and the part is put into a furnace ($59,900) which sinters the part into the desired density.
As for materials, the printer can use over 200 alloys and works with the same metal powders that are used for metal injection moulding. The quality of the parts is comparable to injection moulding as well, according to the company.
