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.
SLA Resin Elastic 50A is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Is Plastic Nylon PA66 stronger than SLA Resin Elastic 50A? Plastic Nylon PA66 is stronger: its yield strength is 85 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (25x).
Which is lighter, Plastic Nylon PA66 or SLA Resin Elastic 50A? SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 1,130 kg/m³ for Plastic Nylon PA66.
Which is lighter for the same job, Plastic Nylon PA66 or SLA Resin Elastic 50A? For the same stiffness or strength: Plastic Nylon PA66 is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic Nylon PA66 SLA Resin Elastic 50A Strong rod or tie lighter 22.3x heavier Strong beam lighter 7.64x heavier Strong panel or plate lighter 4.47x 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).
