Sumitomo Chemical SUMIKASUPER LCP E6006L (30% glass fibre; high strength, low shrinkage); SUMIKASUPER LCP Technical Note, Version 04 / Nov. 2023, typical values.
Ultimaker PLA, 3D-printed specimens, XY (flat) orientation; Ultimaker S5 Pro, engineering intent profile, 0.15 mm layer height, AA 0.4 print core, 100% infill, Cura 4.9, printed one-at-a-time, conditioned >=24 h at room temperature. TDS dated April 20, 2022.
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.
Plastic PLA is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Plastic LCP GF30 stronger than Plastic PLA?
Plastic LCP GF30 is stronger: its tensile strength is 115 MPa against yield strength 52.5 MPa for Plastic PLA (2.19x).
Which is lighter, Plastic LCP GF30 or Plastic PLA?
Plastic PLA is lighter: 1,240 kg/m³ against 1,610 kg/m³ for Plastic LCP GF30.
Which is stiffer, Plastic LCP GF30 or Plastic PLA?
Plastic LCP GF30 is stiffer: Young's modulus 11.5 GPa against 3.25 GPa for Plastic PLA, 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 Plastic PLA?
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.

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 conducts heat better, Plastic LCP GF30 or Plastic PLA?
Plastic LCP GF30 conducts heat better: 0.5 W/m·K against 0.13 W/m·K for Plastic PLA.
