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 and Plastic PETG are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions Mechanical Is FDM ASA stronger than Plastic PETG? Plastic PETG is stronger: its yield strength is 46.2 MPa against tensile strength 37 MPa for FDM ASA (25%).
Which is lighter, FDM ASA or Plastic PETG? FDM ASA is lighter: 1,050 kg/m³ against 1,270 kg/m³ for Plastic PETG.
Which is stiffer, FDM ASA or Plastic PETG? FDM ASA is stiffer: Young's modulus 2.45 GPa against 1.94 GPa for Plastic PETG, so the same part in FDM ASA deflects less under the same load.
Which is lighter for the same job, FDM ASA or Plastic PETG? For the same stiffness or strength: FDM ASA is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong beam, strong panel or plate; Plastic PETG is lighter for a strong rod or tie.
Part that must be FDM ASA Plastic PETG Stiff rod or tie (tension) lighter 1.53x heavier Stiff beam (bending) lighter 36% heavier Stiff panel or plate lighter 31% heavier Strong rod or tie 3% heavier lighter Strong beam lighter 4% heavier Strong panel or plate lighter 8% heavier
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 ASA or Plastic PETG? FDM ASA stretches further before it breaks: 9.2% elongation at break against 7.6% for Plastic PETG.
Thermal Which conducts heat better, FDM ASA or Plastic PETG? Plastic PETG conducts heat better: 0.21 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature? Plastic PETG expands less: 51 µm/m·K against 95 µm/m·K for FDM ASA.
