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.
FDM ASA and SLA Resin Standard are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Mechanical
Is FDM ASA stronger than SLA Resin Standard?
SLA Resin Standard is stronger: its tensile strength is 60 MPa against 37 MPa for FDM ASA (1.62x).
Which is lighter, FDM ASA or SLA Resin Standard?
FDM ASA is lighter: 1,050 kg/m³ against 1,210 kg/m³ for SLA Resin Standard.
Which is stiffer, FDM ASA or SLA Resin Standard?
SLA Resin Standard is stiffer: Young's modulus 2.75 GPa against 2.45 GPa for FDM ASA, so the same part in SLA Resin Standard deflects less under the same load.
Which is lighter for the same job, FDM ASA or SLA Resin Standard?
For the same stiffness or strength: FDM ASA is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; SLA Resin Standard 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, FDM ASA or SLA Resin Standard?
FDM ASA stretches further before it breaks: 9.2% elongation at break against 8% for SLA Resin Standard.
Thermal
Which handles higher temperatures, FDM ASA or SLA Resin Standard?
FDM ASA does: 92 °C against 59 °C for SLA Resin Standard, both HDT 1.8 MPa.
Which conducts heat better, FDM ASA or SLA Resin Standard?
SLA Resin Standard conducts heat better: 0.54 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature?
FDM ASA expands less: 95 µm/m·K against 114 µm/m·K for SLA Resin Standard.
