Abstract Scope |
Inconel 625 material for fully dense single alloy binder jet printing was qualified for printing with a Desktop Metal InnoventX system through a series of testing both in-house and through a third party. Powder was tested prior to printing to determine process parameters based on powder size distribution and flow characteristics. Several builds were completed using the InnoventX qualification print layout to account for build-to-build variation. Parts were sintered and heat treated externally before physical and mechanical testing. Final relative densities were 99%+ and physical and mechanical properties fell within UNS specifications. The composition of the alloy was also within specifications for an Inconel 625 alloy. As a result, the alloy was qualified for use in the InnoventX system and a datasheet with expected mechanical and physical properties was published. |
