17-4PH stainless steel made by bound metal deposition is a precipitation-hardening martensitic stainless steel printed from metal powder bound in a polymer, then debound and sintered into a metal part. The green part is printed oversized to allow for the substantial, fairly predictable shrinkage on sintering, and long or overhanging features need supports or setters to resist sag and distortion. Layer lines leave a rougher surface than machined stock, and some residual porosity and differences between build directions can remain. Sintered parts are commonly aged by heat treatment and machined on critical features. Typical uses are jigs, fixtures, tooling, brackets and low-volume functional parts.
