Plastic TPU and SLA Resin Tough 2000 are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions Mechanical Is Plastic TPU stronger than SLA Resin Tough 2000? SLA Resin Tough 2000 is stronger: its yield strength is 40.4 MPa against tensile strength 23.7 MPa for Plastic TPU (1.7x).
Which is lighter, Plastic TPU or SLA Resin Tough 2000? SLA Resin Tough 2000 is lighter: 1,090 kg/m³ against 1,220 kg/m³ for Plastic TPU.
Which is stiffer, Plastic TPU or SLA Resin Tough 2000? SLA Resin Tough 2000 is stiffer: Young's modulus 1.8 GPa against 0.067 GPa for Plastic TPU, so the same part in SLA Resin Tough 2000 deflects less under the same load.
Which is lighter for the same job, Plastic TPU or SLA Resin Tough 2000? For the same stiffness or strength: SLA Resin Tough 2000 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 TPU SLA Resin Tough 2000 Stiff rod or tie (tension) 30.1x heavier lighter Stiff beam (bending) 5.8x heavier lighter Stiff panel or plate 3.35x heavier lighter Strong rod or tie 1.91x heavier lighter Strong beam 1.6x heavier lighter Strong panel or plate 46% 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).
