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 Iron stronger than SLA Resin Standard?

Iron is stronger: its yield strength is 186 MPa against tensile strength 60 MPa for SLA Resin Standard (3.1x).

Which is stiffer, Iron or SLA Resin Standard?

Iron is stiffer: Young's modulus 207 GPa against 2.75 GPa for SLA Resin Standard, so the same part in Iron deflects less under the same load.
