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.
SLA Resin Elastic 50A is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is SLA Resin Elastic 50A stronger than Steel AISI 1018?
Steel AISI 1018 is stronger: its yield strength is 372 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (109x).
Which is lighter, SLA Resin Elastic 50A or Steel AISI 1018?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 7,861 kg/m³ for Steel AISI 1018.
Which is lighter for the same job, SLA Resin Elastic 50A or Steel AISI 1018?
For the same stiffness or strength: Steel AISI 1018 is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | SLA Resin Elastic 50A | Steel AISI 1018 |
|---|---|---|
| Strong rod or tie | 14.1x heavier | lighter |
| Strong beam | 2.94x 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).
