The 3D Systems ProX DMP320 machine is a high quality direct metal printing machine. It is currently set up to print medical-grade titanium in a 275x275x 420mm build area, with a layer-by-layer additive powder melting process by laser.
The resolution of the machine is sub 100 micrometer and it has the best surface finish of all Titanium 3D printers.
