Each number points to the document that states it, with the exact basis. Values without a number are computed from the sourced ones. "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 Mechanical Is FDM ASA stronger than Plastic Nylon PA6? Plastic Nylon PA6 is stronger: its yield strength is 90 MPa against tensile strength 37 MPa for FDM ASA (2.43x).
Which is lighter, FDM ASA or Plastic Nylon PA6? FDM ASA is lighter: 1,050 kg/m³ against 1,130 kg/m³ for Plastic Nylon PA6.
Which is stiffer, FDM ASA or Plastic Nylon PA6? Plastic Nylon PA6 is stiffer: Young's modulus 3.5 GPa against 2.45 GPa for FDM ASA, so the same part in Plastic Nylon PA6 deflects less under the same load.
Which is lighter for the same job, FDM ASA or Plastic Nylon PA6? For the same stiffness or strength: Plastic Nylon PA6 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 FDM ASA Plastic Nylon PA6 Stiff rod or tie (tension) 33% heavier lighter Stiff beam (bending) 11% heavier lighter Stiff panel or plate 5% heavier lighter Strong rod or tie 2.26x heavier lighter Strong beam 1.68x heavier lighter Strong panel or plate 45% heavier lighter
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).
Thermal Which conducts heat better, FDM ASA or Plastic Nylon PA6? Plastic Nylon PA6 conducts heat better: 0.33 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature? FDM ASA expands less: 95 µm/m·K against 102 µm/m·K for Plastic Nylon PA6.
