Every value links to the document that states it. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
DMLS 17-4PH Stainless Steel and SLA Resin Standard are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is DMLS 17-4PH Stainless Steel stronger than SLA Resin Standard?
DMLS 17-4PH Stainless Steel is stronger: its yield strength is 861 MPa against tensile strength 60 MPa for SLA Resin Standard (14.3x).
Which is stiffer, DMLS 17-4PH Stainless Steel or SLA Resin Standard?
DMLS 17-4PH Stainless Steel is stiffer: Young's modulus 197 GPa against 2.75 GPa for SLA Resin Standard, so the same part in DMLS 17-4PH Stainless Steel deflects less under the same load.
