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 Nylon PA6 stronger than SLA Resin Standard?
Plastic Nylon PA6 is stronger: its yield strength is 90 MPa against tensile strength 60 MPa for SLA Resin Standard (1.5x).
Which is stiffer, Plastic Nylon PA6 or SLA Resin Standard?
Plastic Nylon PA6 is stiffer: Young's modulus 3.5 GPa against 2.75 GPa for SLA Resin Standard, so the same part in Plastic Nylon PA6 deflects less under the same load.
