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.
FDM HIPS and FDM PAHT-CF are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM HIPS stronger than FDM PAHT-CF?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against 18.4 MPa for FDM HIPS (5x).
Which is lighter, FDM HIPS or FDM PAHT-CF?
FDM HIPS is lighter: 1,023 kg/m³ against 1,060 kg/m³ for FDM PAHT-CF.
Which is stiffer, FDM HIPS or FDM PAHT-CF?
FDM PAHT-CF is stiffer: Young's modulus 3.86 GPa against 1.59 GPa for FDM HIPS, so the same part in FDM PAHT-CF deflects less under the same load.
Which is lighter for the same job, FDM HIPS or FDM PAHT-CF?
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 HIPS | FDM PAHT-CF |
|---|---|---|
| Stiff rod or tie (tension) | 2.35x heavier | lighter |
| Stiff beam (bending) | 1.5x heavier | lighter |
| Stiff panel or plate | 30% heavier | lighter |
| Strong rod or tie | 4.83x heavier | lighter |
| Strong beam | 2.82x heavier | lighter |
| Strong panel or plate | 2.16x 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 is more ductile, FDM HIPS or FDM PAHT-CF?
FDM PAHT-CF stretches further before it breaks: 8.4% elongation at break against 1.4% for FDM HIPS.
Which handles higher temperatures, FDM HIPS or FDM PAHT-CF?
FDM PAHT-CF does: 170 °C against 86 °C for FDM HIPS, both HDT 1.8 MPa.
