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.
Plastic PETG is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Is Drywall stronger than Plastic PETG? Plastic PETG is stronger: its yield strength is 46.2 MPa against tensile strength 1.5 MPa for Drywall (30.8x).
Which is stiffer, Drywall or Plastic PETG? Plastic PETG is stiffer: Young's modulus 1.94 GPa against 1.5 GPa for Drywall, so the same part in Plastic PETG deflects less under the same load.
Which expands less with temperature? Drywall expands less: 16.7 µm/m·K against 51 µm/m·K for Plastic PETG.
