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.
SAC305 (Sn96.5Ag3.0Cu0.5) solder alloy, bulk; Indium Corporation Indalloy 256 (SAC305) for Preforms product data sheet (Form No. 100346 R0, 2024), selected properties, test temperature not stated; expansion and specific heat from MacDermid Alpha VACULOY SAC TDS (06 September 2023).
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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is FDM PAHT-CF stronger than Solder SAC305?
FDM PAHT-CF is stronger: its tensile strength is 92 MPa against yield strength 22 MPa for Solder SAC305 (4.18x).
Which is lighter, FDM PAHT-CF or Solder SAC305?
FDM PAHT-CF is lighter: 1,060 kg/m³ against 7,350 kg/m³ for Solder SAC305.
Which is stiffer, FDM PAHT-CF or Solder SAC305?
Solder SAC305 is stiffer: Young's modulus 6.9 GPa against 3.86 GPa for FDM PAHT-CF, so the same part in Solder SAC305 deflects less under the same load.
Which is lighter for the same job, FDM PAHT-CF or Solder SAC305?
For the same stiffness or strength: FDM PAHT-CF 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 is more ductile, FDM PAHT-CF or Solder SAC305?
Solder SAC305 stretches further before it breaks: 49% elongation at break against 8.4% for FDM PAHT-CF.
