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 Tough 2000 is 3D printed: its properties depend on build direction and print settings; these are typical values.

Questions

Is SLA Resin Tough 2000 stronger than Titanium?

Titanium is stronger: its yield strength is 885 MPa against 40.4 MPa for SLA Resin Tough 2000 (21.9x).

Which is lighter, SLA Resin Tough 2000 or Titanium?

SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 4,430 kg/m³ for Titanium.

Which is stiffer, SLA Resin Tough 2000 or Titanium?

Titanium is stiffer: Young's modulus 115 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Titanium deflects less under the same load.

Which is lighter for the same job, SLA Resin Tough 2000 or Titanium?

For the same stiffness or strength: SLA Resin Tough 2000 is lighter for a stiff panel or plate; Titanium is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam, strong panel or plate.

Part that must be	SLA Resin Tough 2000	Titanium
Stiff rod or tie (tension)	15.7x heavier	lighter
Stiff beam (bending)	1.96x heavier	lighter
Stiff panel or plate	lighter	2% heavier
Strong rod or tie	5.39x heavier	lighter
Strong beam	1.93x heavier	lighter
Strong panel or plate	15% 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).

Which expands less with temperature?

Titanium expands less: 9 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
