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 PETG and SLA Resin Standard are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic PETG stronger than SLA Resin Standard?
SLA Resin Standard is stronger: its tensile strength is 60 MPa against yield strength 46.2 MPa for Plastic PETG (30%).
Which is stiffer, Plastic PETG or SLA Resin Standard?
SLA Resin Standard is stiffer: Young's modulus 2.75 GPa against 1.94 GPa for Plastic PETG, so the same part in SLA Resin Standard deflects less under the same load.
