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.
Plastic Nylon and SLA Resin Standard are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic Nylon stronger than SLA Resin Standard?
Plastic Nylon is stronger: its yield strength is 63.1 MPa against tensile strength 60 MPa for SLA Resin Standard (5%).
Which is stiffer, Plastic Nylon or SLA Resin Standard?
SLA Resin Standard is stiffer: Young's modulus 2.75 GPa against 2.33 GPa for Plastic Nylon, so the same part in SLA Resin Standard deflects less under the same load.
