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 Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is stronger: its yield strength is 885 MPa against tensile strength 37 MPa for FDM ASA (23.9x).
Which is lighter, FDM ASA or Titanium Ti-6Al-4V?
FDM ASA is lighter: 1,050 kg/m³ against 4,430 kg/m³ for Titanium Ti-6Al-4V.
Which is stiffer, FDM ASA or Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V is stiffer: Young's modulus 115 GPa against 2.45 GPa for FDM ASA, so the same part in Titanium Ti-6Al-4V deflects less under the same load.
Which is lighter for the same job, FDM ASA or Titanium Ti-6Al-4V?
For the same stiffness or strength: FDM ASA is lighter for a stiff panel or plate; Titanium Ti-6Al-4V is lighter for a stiff rod or tie (tension), stiff beam (bending), strong rod or tie, strong beam, strong panel or plate.
| Part that must be | FDM ASA | Titanium Ti-6Al-4V |
|---|---|---|
| Stiff rod or tie (tension) | 11.1x heavier | lighter |
| Stiff beam (bending) | 1.62x heavier | lighter |
| Stiff panel or plate | lighter | 17% heavier |
| Strong rod or tie | 5.67x heavier | lighter |
| Strong beam | 1.97x heavier | lighter |
| Strong panel or plate | 16% 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 conducts heat better, FDM ASA or Titanium Ti-6Al-4V?
Titanium Ti-6Al-4V conducts heat better: 6.6 W/m·K against 0.17 W/m·K for FDM ASA.
Which expands less with temperature?
Titanium Ti-6Al-4V expands less: 9 µm/m·K against 95 µm/m·K for FDM ASA.
