Bambu Lab PAHT-CF, TDS V3.0, printed specimens X-Y, dry state; nozzle 290 °C, bed 100 °C, 100 mm/s, 100% infill; annealed and dried 80 °C for 12 h before testing.
Formlabs Elastic 50A Resin V2 (FLELCL02), TDS Rev. 01 24.01.2024; parts printed on Form 3, 100 µm, Elastic 50A V2 settings and post-processing; tensile on Die C specimens cut from printed sheets after 3+ h at 23 °C.
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.
FDM PAHT-CF and SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than SLA Resin Elastic 50A?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against 3.4 MPa for SLA Resin Elastic 50A (27.1x).
Which is lighter, FDM PAHT-CF or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 1,060 kg/m³ for FDM PAHT-CF.
Which is lighter for the same job, FDM PAHT-CF or SLA Resin Elastic 50A?
For the same stiffness or strength: FDM PAHT-CF is lighter for a 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 is more ductile, FDM PAHT-CF or SLA Resin Elastic 50A?
SLA Resin Elastic 50A stretches further before it breaks: 160% elongation at break against 8.4% for FDM PAHT-CF.
