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 Stainless 17-4PH?

Stainless 17-4PH is stronger: its yield strength is 1,275 MPa against 40.4 MPa for SLA Resin Tough 2000 (31.6x).

Which is lighter, SLA Resin Tough 2000 or Stainless 17-4PH?

SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 7,800 kg/m³ for Stainless 17-4PH.

Which is stiffer, SLA Resin Tough 2000 or Stainless 17-4PH?

Stainless 17-4PH is stiffer: Young's modulus 197 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Stainless 17-4PH deflects less under the same load.

Which is lighter for the same job, SLA Resin Tough 2000 or Stainless 17-4PH?

For the same stiffness or strength: SLA Resin Tough 2000 is lighter for a stiff panel or plate, strong panel or plate; Stainless 17-4PH is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam.

Part that must be	SLA Resin Tough 2000	Stainless 17-4PH
Stiff rod or tie (tension)	15.3x heavier	lighter
Stiff beam (bending)	46% heavier	lighter
Stiff panel or plate	lighter	50% heavier
Strong rod or tie	4.41x heavier	lighter
Strong beam	40% heavier	lighter
Strong panel or plate	lighter	27% 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).

Which expands less with temperature?

Stainless 17-4PH expands less: 10.8 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
