316L Stainless Steel (L-PBF, 3D Systems LaserForm 316L (A), as-built)

LaserForm 316L (A) is 3D Systems' grade of 316L austenitic stainless steel for laser powder bed fusion, here in the as-built condition. Rapid melt pool solidification gives a fine cellular austenitic substructure with columnar grains along the build direction. This makes it stronger than annealed wrought 316L, with some anisotropy between build directions. As-built parts carry residual stress, remain attached to the plate and supports, and have a rough surface, so they usually need stress relief, support removal and machining or polishing of functional faces. Printed parts serve as corrosion-resistant fluid-handling components, manifolds, brackets and tooling with internal channels. Every value on this page is read from 3D Systems' 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.
