3D Systems LaserForm 17-4PH (A) in the as-built condition is 17-4PH precipitation-hardening stainless steel printed from this maker's powder by laser powder bed fusion, before any stress relief or heat treatment. Rapid solidification leaves a fine columnar structure of martensite with a variable share of retained austenite, along with residual stress, anisotropy between build directions and rough supported surfaces. Parts are cut from the build plate and are normally stress relieved, then solution treated and aged to develop the alloy's intended strength. Printed parts serve as tooling inserts with conformal cooling, pump and valve components and structural brackets. 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.
