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.
Plastic ABS and SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic ABS stronger than SLA Resin Elastic 50A?
Plastic ABS is stronger: its yield strength is 38.1 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (11.2x).
Which is lighter, Plastic ABS or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 1,100 kg/m³ for Plastic ABS.
Which is lighter for the same job, Plastic ABS or SLA Resin Elastic 50A?
For the same stiffness or strength: Plastic ABS is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Plastic ABS | SLA Resin Elastic 50A |
|---|---|---|
| Strong rod or tie | lighter | 10.3x heavier |
| Strong beam | lighter | 4.6x heavier |
| Strong panel or plate | lighter | 3.07x 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, Plastic ABS or SLA Resin Elastic 50A?
SLA Resin Elastic 50A stretches further before it breaks: 160% elongation at break against 4.6% for Plastic ABS.
