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 Tough 2000 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic PBT GF30 stronger than SLA Resin Tough 2000?
Plastic PBT GF30 is stronger: its tensile strength is 140 MPa against yield strength 40.4 MPa for SLA Resin Tough 2000 (3.47x).
Which is lighter, Plastic PBT GF30 or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 1,530 kg/m³ for Plastic PBT GF30.
Which is stiffer, Plastic PBT GF30 or SLA Resin Tough 2000?
Plastic PBT GF30 is stiffer: Young's modulus 9.8 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Plastic PBT GF30 deflects less under the same load.
Which is lighter for the same job, Plastic PBT GF30 or SLA Resin Tough 2000?
For the same stiffness or strength: Plastic PBT GF30 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
Part that must be

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
Which handles higher temperatures, Plastic PBT GF30 or SLA Resin Tough 2000?
Plastic PBT GF30 does: 205 °C against 57 °C for SLA Resin Tough 2000, both HDT 1.8 MPa.
Which expands less with temperature?
Plastic PBT GF30 expands less: 25 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
