JIS ADC12 (Al-Si-Cu, about A383 / EN AC-46100) high-pressure die-casting alloy, as cast; physical properties from Daiki Aluminium Industry (ADC12 ingot producer) measured values; modulus from S.S.Aluminum (ADC12 ingot producer) standard values.
Formlabs Tough 2000 Resin V2 (FLTO2002), TDS Rev. 01 10/06/2025; printed on Form 4 at 100 µm, washed in Form Wash V2 10+5 min in >=99% IPA, post-cured 70 °C for 12 min in Form Cure V2. Orientation not stated.
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 Aluminum ADC12 stronger than SLA Resin Tough 2000?
Aluminum ADC12 is stronger: its yield strength is 149 MPa against 40.4 MPa for SLA Resin Tough 2000 (3.69x).
Which is lighter, Aluminum ADC12 or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 2,680 kg/m³ for Aluminum ADC12.
Which is stiffer, Aluminum ADC12 or SLA Resin Tough 2000?
Aluminum ADC12 is stiffer: Young's modulus 79.8 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Aluminum ADC12 deflects less under the same load.
Which is lighter for the same job, Aluminum ADC12 or SLA Resin Tough 2000?
For the same stiffness or strength: Aluminum ADC12 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie; SLA Resin Tough 2000 is lighter for a 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 expands less with temperature?
Aluminum ADC12 expands less: 21 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
