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.
Plastic ABS is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions Mechanical Is Plastic ABS stronger than Plastic POM/Acetal? Plastic POM/Acetal is stronger: its yield strength is 69 MPa against 38.1 MPa for Plastic ABS (1.81x).
Which is lighter, Plastic ABS or Plastic POM/Acetal? Plastic ABS is lighter: 1,100 kg/m³ against 1,420 kg/m³ for Plastic POM/Acetal.
Which is stiffer, Plastic ABS or Plastic POM/Acetal? Plastic POM/Acetal is stiffer: Young's modulus 2.8 GPa against 1.96 GPa for Plastic ABS, so the same part in Plastic POM/Acetal deflects less under the same load.
Which is lighter for the same job, Plastic ABS or Plastic POM/Acetal? For the same stiffness or strength: Plastic ABS is lighter for a stiff beam (bending), stiff panel or plate; Plastic POM/Acetal is lighter for a stiff rod or tie (tension), strong rod or tie, strong beam, strong panel or plate.
Part that must be Plastic ABS Plastic POM/Acetal Stiff rod or tie (tension) 11% heavier lighter Stiff beam (bending) lighter 8% heavier Stiff panel or plate lighter 15% heavier Strong rod or tie 40% heavier lighter Strong beam 15% heavier lighter Strong panel or plate 4% 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).
Which is more ductile, Plastic ABS or Plastic POM/Acetal? Plastic POM/Acetal stretches further before it breaks: 75% elongation at break against 4.6% for Plastic ABS.
Thermal Which conducts heat better, Plastic ABS or Plastic POM/Acetal? Plastic POM/Acetal conducts heat better: 0.4 W/m·K against 0.17 W/m·K for Plastic ABS.
Which expands less with temperature? Plastic ABS expands less: 95 µm/m·K against 122 µm/m·K for Plastic POM/Acetal.
