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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Nickel Inconel 718 stronger than SLA Resin Standard?
Nickel Inconel 718 is stronger: its yield strength is 1,207 MPa against tensile strength 60 MPa for SLA Resin Standard (20.1x).
Which is stiffer, Nickel Inconel 718 or SLA Resin Standard?
Nickel Inconel 718 is stiffer: Young's modulus 200 GPa against 2.75 GPa for SLA Resin Standard, so the same part in Nickel Inconel 718 deflects less under the same load.
