Questions
Is FDM PAHT-CF stronger than SLA Resin Tough 2000?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 40.4 MPa for SLA Resin Tough 2000 (2.28x).
Which is lighter, FDM PAHT-CF or SLA Resin Tough 2000?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 1,090 kg/m³ for SLA Resin Tough 2000.
Which is stiffer, FDM PAHT-CF or SLA Resin Tough 2000?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in FDM PAHT-CF deflects less under the same load.
Which is lighter for the same job, FDM PAHT-CF or SLA Resin Tough 2000?
For the same stiffness or strength: FDM PAHT-CF 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 | FDM PAHT-CF | SLA Resin Tough 2000 |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 2.21x heavier |
| Stiff beam (bending) | lighter | 1.51x heavier |
| Stiff panel or plate | lighter | 33% heavier |
| Strong rod or tie | lighter | 2.34x heavier |
| Strong beam | lighter | 1.78x heavier |
| Strong panel or plate | lighter | 1.55x 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 is more ductile, FDM PAHT-CF or SLA Resin Tough 2000?
SLA Resin Tough 2000 stretches further before it breaks: 79% elongation at break against 8.4% for FDM PAHT-CF.
Which handles higher temperatures, FDM PAHT-CF or SLA Resin Tough 2000?
FDM PAHT-CF does: 170 °C against 57 °C for SLA Resin Tough 2000, both HDT 1.8 MPa.
