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 SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM HIPS stronger than SLA Resin Elastic 50A?
FDM HIPS is stronger: its tensile strength is 18.4 MPa against 3.4 MPa for SLA Resin Elastic 50A (5.41x).
Which is lighter, FDM HIPS or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 1,023 kg/m³ for FDM HIPS.
Which is lighter for the same job, FDM HIPS or SLA Resin Elastic 50A?
For the same stiffness or strength: FDM HIPS is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | FDM HIPS | SLA Resin Elastic 50A |
|---|---|---|
| Strong rod or tie | lighter | 5.34x heavier |
| Strong beam | lighter | 3.04x heavier |
| Strong panel or plate | lighter | 2.3x 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 HIPS or SLA Resin Elastic 50A?
SLA Resin Elastic 50A stretches further before it breaks: 160% elongation at break against 1.4% for FDM HIPS.
