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 Plastic HDPE stronger than SLA Resin Standard?

SLA Resin Standard is stronger: its tensile strength is 60 MPa against yield strength 24 MPa for Plastic HDPE (2.5x).

Which is stiffer, Plastic HDPE or SLA Resin Standard?

SLA Resin Standard is stiffer: Young's modulus 2.75 GPa against 0.9 GPa for Plastic HDPE, so the same part in SLA Resin Standard deflects less under the same load.
