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.
SLS PA12 Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Is SLS PA12 Nylon stronger than Plastic PTFE? SLS PA12 Nylon is stronger: its tensile strength is 48 MPa against yield strength 9 MPa for Plastic PTFE (5.33x).
Which is lighter, SLS PA12 Nylon or Plastic PTFE? SLS PA12 Nylon is lighter: 930 kg/m³ against 2,160 kg/m³ for Plastic PTFE.
Which is lighter for the same job, SLS PA12 Nylon or Plastic PTFE? For the same stiffness or strength: SLS PA12 Nylon is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be SLS PA12 Nylon Plastic PTFE Strong rod or tie lighter 12.4x heavier Strong beam lighter 7.09x heavier Strong panel or plate lighter 5.36x 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).
