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 Brass C360 stronger than SLA Resin Tough 2000?
Brass C360 is stronger: its yield strength is 310 MPa against 40.4 MPa for SLA Resin Tough 2000 (7.67x).
Which is lighter, Brass C360 or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or SLA Resin Tough 2000?
Brass C360 is stiffer: Young's modulus 96.5 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Brass C360 deflects less under the same load.
Which is lighter for the same job, Brass C360 or SLA Resin Tough 2000?
For the same stiffness or strength: Brass C360 is lighter for a stiff rod or tie (tension); SLA Resin Tough 2000 is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Brass C360 | SLA Resin Tough 2000 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 6.88x heavier |
| Stiff beam (bending) | 6% heavier | lighter |
| Stiff panel or plate | 2.07x heavier | lighter |
| Strong rod or tie | 2% heavier | lighter |
| Strong beam | 2x heavier | lighter |
| Strong panel or plate | 2.81x heavier | lighter |
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?
Brass C360 expands less: 20.5 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
