Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "Not sourced" means no citable source states it (or only a specification minimum); figures computed from it are left out too.
Plastic ABS and SLA Resin Tough 2000 are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Mechanical
Is Plastic ABS stronger than SLA Resin Tough 2000?
SLA Resin Tough 2000 is stronger: its yield strength is 40.4 MPa against 38.1 MPa for Plastic ABS (6%).
Which is lighter, Plastic ABS or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 1,100 kg/m³ for Plastic ABS.
Which is stiffer, Plastic ABS or SLA Resin Tough 2000?
Plastic ABS is stiffer: Young's modulus 1.96 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Plastic ABS deflects less under the same load.
Which is lighter for the same job, Plastic ABS or SLA Resin Tough 2000?
For the same stiffness or strength: Plastic ABS is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; SLA Resin Tough 2000 is lighter for a strong rod or tie, strong beam, strong panel or plate.

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 is more ductile, Plastic ABS or SLA Resin Tough 2000?
SLA Resin Tough 2000 stretches further before it breaks: 79% elongation at break against 4.6% for Plastic ABS.
Thermal
Which expands less with temperature?
Plastic ABS expands less: 95 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
