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 SLA Resin Standard stronger than Steel AISI 1018?
Steel AISI 1018 is stronger: its yield strength is 372 MPa against tensile strength 60 MPa for SLA Resin Standard (6.2x).
Which is stiffer, SLA Resin Standard or Steel AISI 1018?
Steel AISI 1018 is stiffer: Young's modulus 200 GPa against 2.75 GPa for SLA Resin Standard, so the same part in Steel AISI 1018 deflects less under the same load.
