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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is FDM HIPS stronger than Plastic ABS (bulk/injection)?
Plastic ABS (bulk/injection) is stronger: its yield strength is 45 MPa against tensile strength 18.4 MPa for FDM HIPS (2.45x).
Which is lighter, FDM HIPS or Plastic ABS (bulk/injection)?
FDM HIPS is lighter: 1,023 kg/m³ against 1,040 kg/m³ for Plastic ABS (bulk/injection).
Which is stiffer, FDM HIPS or Plastic ABS (bulk/injection)?
Plastic ABS (bulk/injection) is stiffer: Young's modulus 2.3 GPa against 1.59 GPa for FDM HIPS, so the same part in Plastic ABS (bulk/injection) deflects less under the same load.
Which is lighter for the same job, FDM HIPS or Plastic ABS (bulk/injection)?
For the same stiffness or strength: Plastic ABS (bulk/injection) 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 ABS (bulk/injection) |
|---|---|---|
| Stiff rod or tie (tension) | 42% heavier | lighter |
| Stiff beam (bending) | 18% heavier | lighter |
| Stiff panel or plate | 11% heavier | lighter |
| Strong rod or tie | 2.41x heavier | lighter |
| Strong beam | 1.79x heavier | lighter |
| Strong panel or plate | 1.54x 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 conducts heat better, FDM HIPS or Plastic ABS (bulk/injection)?
FDM HIPS conducts heat better: 0.17 W/m·K against 0.17 W/m·K for Plastic ABS (bulk/injection).
Which expands less with temperature?
FDM HIPS expands less: 80 µm/m·K against 95 µm/m·K for Plastic ABS (bulk/injection).
