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.
SLA Resin Standard and DMLS 316L Stainless Steel are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is SLA Resin Standard stronger than DMLS 316L Stainless Steel?
DMLS 316L Stainless Steel is stronger: its yield strength is 530 MPa against tensile strength 60 MPa for SLA Resin Standard (8.83x).
Which is stiffer, SLA Resin Standard or DMLS 316L Stainless Steel?
DMLS 316L Stainless Steel is stiffer: Young's modulus 185 GPa against 2.75 GPa for SLA Resin Standard, so the same part in DMLS 316L Stainless Steel deflects less under the same load.
