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 ASA and FDM HIPS are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM ASA stronger than FDM HIPS?
FDM ASA is stronger: its tensile strength is 37 MPa against 18.4 MPa for FDM HIPS (2.01x).
Which is lighter, FDM ASA or FDM HIPS?
FDM HIPS is lighter: 1,023 kg/m³ against 1,050 kg/m³ for FDM ASA.
Which is stiffer, FDM ASA or FDM HIPS?
FDM ASA is stiffer: Young's modulus 2.45 GPa against 1.59 GPa for FDM HIPS, so the same part in FDM ASA deflects less under the same load.
Which is lighter for the same job, FDM ASA or FDM HIPS?
For the same stiffness or strength: FDM ASA 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 ASA | FDM HIPS |
|---|---|---|
| Stiff rod or tie (tension) | lighter | 1.5x heavier |
| Stiff beam (bending) | lighter | 21% heavier |
| Stiff panel or plate | lighter | 13% heavier |
| Strong rod or tie | lighter | 1.96x heavier |
| Strong beam | lighter | 1.55x heavier |
| Strong panel or plate | lighter | 38% 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 ASA or FDM HIPS?
FDM ASA stretches further before it breaks: 9.2% elongation at break against 1.4% for FDM HIPS.
Which conducts heat better, FDM ASA or FDM HIPS?
FDM ASA conducts heat better: 0.17 W/m·K against 0.17 W/m·K for FDM HIPS.
Which expands less with temperature?
FDM HIPS expands less: 80 µm/m·K against 95 µm/m·K for FDM ASA.
