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 Nylon and SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic Nylon stronger than SLA Resin Elastic 50A?
Plastic Nylon is stronger: its yield strength is 63.1 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (18.6x).
Which is lighter, Plastic Nylon or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 1,140 kg/m³ for Plastic Nylon.
Which is lighter for the same job, Plastic Nylon or SLA Resin Elastic 50A?
For the same stiffness or strength: Plastic Nylon is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | Plastic Nylon | SLA Resin Elastic 50A |
|---|---|---|
| Strong rod or tie | lighter | 16.4x heavier |
| Strong beam | lighter | 6.21x heavier |
| Strong panel or plate | lighter | 3.82x 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).
