FDM HIPS is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is FDM HIPS stronger than Plastic PPS GF40?
Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against 18.4 MPa for FDM HIPS (10.6x).
Which is lighter, FDM HIPS or Plastic PPS GF40?
FDM HIPS is lighter: 1,023 kg/m³ against 1,650 kg/m³ for Plastic PPS GF40.
Which is stiffer, FDM HIPS or Plastic PPS GF40?
Plastic PPS GF40 is stiffer: Young's modulus 14.7 GPa against 1.59 GPa for FDM HIPS, so the same part in Plastic PPS GF40 deflects less under the same load.
Which is lighter for the same job, FDM HIPS or Plastic PPS GF40?
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 | FDM HIPS | Plastic PPS GF40 |
|---|---|---|
| Stiff rod or tie (tension) | 5.74x heavier | lighter |
| Stiff beam (bending) | 1.89x heavier | lighter |
| Stiff panel or plate | 30% heavier | lighter |
| Strong rod or tie | 6.57x heavier | lighter |
| Strong beam | 2.99x heavier | lighter |
| Strong panel or plate | 2.02x 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 handles higher temperatures, FDM HIPS or Plastic PPS GF40?
Plastic PPS GF40 does: 270 °C against 86 °C for FDM HIPS, both HDT 1.8 MPa.
Which conducts heat better, FDM HIPS or Plastic PPS GF40?
Plastic PPS GF40 conducts heat better: 0.2 W/m·K against 0.17 W/m·K for FDM HIPS.
Which expands less with temperature?
Plastic PPS GF40 expands less: 12 µm/m·K against 80 µm/m·K for FDM HIPS.
