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 Plastic PPS GF40 stronger than SLA Resin Tough 2000?
Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against yield strength 40.4 MPa for SLA Resin Tough 2000 (4.83x).
Which is lighter, Plastic PPS GF40 or SLA Resin Tough 2000?
SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 1,650 kg/m³ for Plastic PPS GF40.
Which is stiffer, Plastic PPS GF40 or SLA Resin Tough 2000?
Plastic PPS GF40 is stiffer: Young's modulus 14.7 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Plastic PPS GF40 deflects less under the same load.
Which is lighter for the same job, Plastic PPS GF40 or SLA Resin Tough 2000?
For the same stiffness or strength: Plastic PPS GF40 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Plastic PPS GF40 | SLA Resin Tough 2000 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 5.39x heavier |
| Stiff beam (bending) | lighter | 1.89x heavier |
| Stiff panel or plate | lighter | 33% heavier |
| Strong rod or tie | lighter | 3.19x heavier |
| Strong beam | lighter | 1.89x heavier |
| Strong panel or plate | lighter | 45% heavier |
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 handles higher temperatures, Plastic PPS GF40 or SLA Resin Tough 2000?
Plastic PPS GF40 does: 270 °C against 57 °C for SLA Resin Tough 2000, both HDT 1.8 MPa.
Which expands less with temperature?
Plastic PPS GF40 expands less: 12 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
