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 Titanium Ti-6Al-4V?

Titanium Ti-6Al-4V is stronger: its yield strength is 885 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (260x).

Which is lighter, SLA Resin Elastic 50A or Titanium Ti-6Al-4V?

SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 4,430 kg/m³ for Titanium Ti-6Al-4V.

Which is lighter for the same job, SLA Resin Elastic 50A or Titanium Ti-6Al-4V?

For the same stiffness or strength: Titanium Ti-6Al-4V is lighter for a strong rod or tie, strong beam, strong panel or plate.

Part that must be	SLA Resin Elastic 50A	Titanium Ti-6Al-4V
Strong rod or tie	59.3x heavier	lighter
Strong beam	9.29x heavier	lighter
Strong panel or plate	3.68x 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).
