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.
SLA Resin Tough 2000 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Mechanical Is Plastic Nylon PA66 stronger than SLA Resin Tough 2000? Plastic Nylon PA66 is stronger: its yield strength is 85 MPa against 40.4 MPa for SLA Resin Tough 2000 (2.1x).
Which is lighter, Plastic Nylon PA66 or SLA Resin Tough 2000? SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 1,130 kg/m³ for Plastic Nylon PA66.
Which is stiffer, Plastic Nylon PA66 or SLA Resin Tough 2000? Plastic Nylon PA66 is stiffer: Young's modulus 3 GPa against 1.8 GPa for SLA Resin Tough 2000, so the same part in Plastic Nylon PA66 deflects less under the same load.
Which is lighter for the same job, Plastic Nylon PA66 or SLA Resin Tough 2000? For the same stiffness or strength: Plastic Nylon PA66 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 Plastic Nylon PA66 SLA Resin Tough 2000 Stiff rod or tie (tension) lighter 1.61x heavier Stiff beam (bending) lighter 25% heavier Stiff panel or plate lighter 14% heavier Strong rod or tie lighter 2.03x heavier Strong beam lighter 1.58x heavier Strong panel or plate lighter 40% 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, Plastic Nylon PA66 or SLA Resin Tough 2000? SLA Resin Tough 2000 stretches further before it breaks: 79% elongation at break against 30% for Plastic Nylon PA66.
Thermal Which expands less with temperature? Plastic Nylon PA66 expands less: 98 µm/m·K against 134 µm/m·K for SLA Resin Tough 2000.
