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.
SLA Resin Tough 2000 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Mechanical
Is Aluminum 3003-O stronger than SLA Resin Tough 2000?
SLA Resin Tough 2000 is stronger: its yield strength is 40.4 MPa against 40 MPa for Aluminum 3003-O (1%).
Which is lighter, Aluminum 3003-O or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 2,730 kg/m³ for Aluminum 3003-O.
Which is stiffer, Aluminum 3003-O or SLA Resin Tough 2000?
Aluminum 3003-O is stiffer: Young's modulus 69 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Aluminum 3003-O deflects less under the same load.
Which is lighter for the same job, Aluminum 3003-O or SLA Resin Tough 2000?
For the same stiffness or strength: Aluminum 3003-O 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, Aluminum 3003-O or SLA Resin Tough 2000?
SLA Resin Tough 2000 stretches further before it breaks: 79% elongation at break against 30% for Aluminum 3003-O.
Thermal
Which expands less with temperature?
Aluminum 3003-O expands less: 23.2 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
