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 Ceramic Alumina 96% stronger than SLA Resin Tough 2000?
Ceramic Alumina 96% is stronger: its tensile strength is 221 MPa against yield strength 40.4 MPa for SLA Resin Tough 2000 (5.47x).
Which is lighter, Ceramic Alumina 96% or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 3,720 kg/m³ for Ceramic Alumina 96%.
Which is stiffer, Ceramic Alumina 96% or SLA Resin Tough 2000?
Ceramic Alumina 96% is stiffer: Young's modulus 303 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Ceramic Alumina 96% deflects less under the same load.
Which is lighter for the same job, Ceramic Alumina 96% or SLA Resin Tough 2000?
For the same stiffness or strength: Ceramic Alumina 96% 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.
| Part that must be | Ceramic Alumina 96% | SLA Resin Tough 2000 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 49.3x heavier |
| Stiff beam (bending) | lighter | 3.8x heavier |
| Stiff panel or plate | lighter | 1.62x heavier |
| Strong rod or tie | lighter | 1.6x heavier |
| Strong beam | 10% heavier | lighter |
| Strong panel or plate | 46% 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?
Ceramic Alumina 96% expands less: 8.2 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
