316L Stainless Steel (BMD)

316L stainless steel made by bound metal deposition is the low-carbon, molybdenum-alloyed austenitic grade, printed from metal-filled polymer filament and then debound and sintered into metal. The green part is printed oversize to allow for sintering shrinkage, and supports or a ceramic interface layer are often needed to limit distortion in the furnace. Sintered parts are largely dense but can keep fine residual porosity, with layer lines and some anisotropy between build directions. Critical surfaces are usually machined or polished. Typical uses are corrosion-resistant fixtures, tooling, housings and low-volume fluid-handling parts.
