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.
FDM ASA is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is FDM ASA stronger than Copper C110?
Copper C110 is stronger: its yield strength is 69 MPa against tensile strength 37 MPa for FDM ASA (1.86x).
Which is lighter, FDM ASA or Copper C110?
FDM ASA is lighter: 1,050 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, FDM ASA or Copper C110?
Copper C110 is stiffer: Young's modulus 117 GPa against 2.45 GPa for FDM ASA, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, FDM ASA or Copper C110?
For the same stiffness or strength: FDM ASA is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate; Copper C110 is lighter for a stiff rod or tie (tension).
| Part that must be | FDM ASA | Copper C110 |
|---|---|---|
| Stiff rod or tie (tension) | 5.64x heavier | lighter |
| Stiff beam (bending) | lighter | 23% heavier |
| Stiff panel or plate | lighter | 2.34x heavier |
| Strong rod or tie | lighter | 4.55x heavier |
| Strong beam | lighter | 5.6x heavier |
| Strong panel or plate | lighter | 6.22x 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 conducts heat better, FDM ASA or Copper C110?
Copper C110 conducts heat better: 391 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature?
Copper C110 expands less: 16.9 µm/m·K against 95 µm/m·K for FDM ASA.
