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 Plastic ABS are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM HIPS stronger than Plastic ABS?
Plastic ABS is stronger: its yield strength is 38.1 MPa against tensile strength 18.4 MPa for FDM HIPS (2.07x).
Which is lighter, FDM HIPS or Plastic ABS?
FDM HIPS is lighter: 1,023 kg/m³ against 1,100 kg/m³ for Plastic ABS.
Which is stiffer, FDM HIPS or Plastic ABS?
Plastic ABS is stiffer: Young's modulus 1.96 GPa against 1.59 GPa for FDM HIPS, so the same part in Plastic ABS deflects less under the same load.
Which is lighter for the same job, FDM HIPS or Plastic ABS?
For the same stiffness or strength: Plastic ABS is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam, strong panel or plate.
| Part that must be | FDM HIPS | Plastic ABS |
|---|---|---|
| Stiff rod or tie (tension) | 15% heavier | lighter |
| Stiff beam (bending) | 3% heavier | lighter |
| Stiff panel or plate | about equal | about equal |
| Strong rod or tie | 1.93x heavier | lighter |
| Strong beam | 1.51x heavier | lighter |
| Strong panel or plate | 34% 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 Plastic ABS?
Plastic ABS stretches further before it breaks: 4.6% elongation at break against 1.4% for FDM HIPS.
Which conducts heat better, FDM HIPS or Plastic ABS?
FDM HIPS conducts heat better: 0.17 W/m·K against 0.17 W/m·K for Plastic ABS.
Which expands less with temperature?
FDM HIPS expands less: 80 µm/m·K against 95 µm/m·K for Plastic ABS.
