Plastic TPU is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Mechanical Is Plastic Polypropylene stronger than Plastic TPU? Plastic Polypropylene is stronger: its yield strength is 33 MPa against tensile strength 23.7 MPa for Plastic TPU (39%).
Which is lighter, Plastic Polypropylene or Plastic TPU? Plastic Polypropylene is lighter: 900 kg/m³ against 1,220 kg/m³ for Plastic TPU.
Which is stiffer, Plastic Polypropylene or Plastic TPU? Plastic Polypropylene is stiffer: Young's modulus 1.45 GPa against 0.067 GPa for Plastic TPU, so the same part in Plastic Polypropylene deflects less under the same load.
Which is lighter for the same job, Plastic Polypropylene or Plastic TPU? For the same stiffness or strength: Plastic Polypropylene 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 Polypropylene Plastic TPU Stiff rod or tie (tension) lighter 29.3x heavier Stiff beam (bending) lighter 6.31x heavier Stiff panel or plate lighter 3.78x heavier Strong rod or tie lighter 1.89x heavier Strong beam lighter 1.69x heavier Strong panel or plate lighter 1.6x 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).
