Bambu Lab ASA, TDS V3.0, printed specimens X-Y; nozzle 260 °C, bed 80 °C, 200 mm/s, 100% infill; annealed and dried 80 °C for 12 h before testing.
Celanese Fortron 1140L4 (PPS, 40% glass fibre), injection moulding; FORTRON PPS Short-Term Properties Guide (PPS-012, 2016); thermal conductivity and Poisson for 40% glass-reinforced Fortron from the Fortron PPS Design Manual (PPS-050, 2013).
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 ASA is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is FDM ASA stronger than Plastic PPS GF40?
Plastic PPS GF40 is stronger: its tensile strength is 195 MPa against 37 MPa for FDM ASA (5.27x).
Which is lighter, FDM ASA or Plastic PPS GF40?
FDM ASA is lighter: 1,050 kg/m³ against 1,650 kg/m³ for Plastic PPS GF40.
Which is stiffer, FDM ASA or Plastic PPS GF40?
Plastic PPS GF40 is stiffer: Young's modulus 14.7 GPa against 2.45 GPa for FDM ASA, so the same part in Plastic PPS GF40 deflects less under the same load.
Which is lighter for the same job, FDM ASA or Plastic PPS GF40?
For the same stiffness or strength: Plastic PPS GF40 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

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 handles higher temperatures, FDM ASA or Plastic PPS GF40?
Plastic PPS GF40 does: 270 °C against 92 °C for FDM ASA, both HDT 1.8 MPa.
Which conducts heat better, FDM ASA or Plastic PPS GF40?
Plastic PPS GF40 conducts heat better: 0.2 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature?
Plastic PPS GF40 expands less: 12 µm/m·K against 95 µm/m·K for FDM ASA.
