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 Plastic LCP GF30 stronger than SLA Resin Tough 2000?

Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 40.4 MPa for SLA Resin Tough 2000 (2.85x).

Which is lighter, Plastic LCP GF30 or SLA Resin Tough 2000?

SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.

Which is stiffer, Plastic LCP GF30 or SLA Resin Tough 2000?

Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Plastic LCP GF30 deflects less under the same load.

Which is lighter for the same job, Plastic LCP GF30 or SLA Resin Tough 2000?

For the same stiffness or strength: Plastic LCP GF30 is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

Part that must be	Plastic LCP GF30	SLA Resin Tough 2000
Stiff rod or tie (tension)	lighter	4.33x heavier
Stiff beam (bending)	lighter	1.71x heavier
Stiff panel or plate	lighter	26% heavier
Strong rod or tie	lighter	1.93x heavier
Strong beam	lighter	36% heavier
Strong panel or plate	lighter	14% 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?

Plastic LCP GF30 expands less: 20 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
