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.
DMLS AlSi10Mg Aluminum and SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is DMLS AlSi10Mg Aluminum stronger than SLA Resin Elastic 50A?
DMLS AlSi10Mg Aluminum is stronger: its yield strength is 270 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (79.4x).
Which is lighter, DMLS AlSi10Mg Aluminum or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 2,670 kg/m³ for DMLS AlSi10Mg Aluminum.
Which is lighter for the same job, DMLS AlSi10Mg Aluminum or SLA Resin Elastic 50A?
For the same stiffness or strength: DMLS AlSi10Mg Aluminum is lighter for a strong rod or tie, strong beam, strong panel or plate.
| Part that must be | DMLS AlSi10Mg Aluminum | SLA Resin Elastic 50A |
|---|---|---|
| Strong rod or tie | lighter | 30x heavier |
| Strong beam | lighter | 6.99x heavier |
| Strong panel or plate | lighter | 3.37x 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).
