Desktop Metal 316L Stainless Steel (Studio System 2) is the maker's 316L austenitic stainless steel for bound metal deposition, printed from rods of metal powder in a polymer and wax binder and used in the sintered condition. Parts are extruded oversize, then debound and sintered, shrinking toward near-full density, with a ceramic interface layer letting supports separate after sintering. Sintering rather than melting gives an equiaxed austenitic structure free of melt-induced residual stress, but leaves some porosity, visible layer lines and a surface that often needs machining on critical faces. Parts serve as prototypes, jigs, fixtures and low-volume functional parts. Every value on this page is read from Desktop Metal's own material data sheet — quoted, cited and dated — and is the maker's statement about printed material, not a measurement by MatWorld; none has yet been reviewed by a person.
