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.

DMLS AlSi10Mg Aluminum and DMLS Ti-6Al-4V ELI Titanium are 3D printed: their properties depend on build direction and print settings; these are typical values.

Questions

Mechanical

Is DMLS AlSi10Mg Aluminum stronger than DMLS Ti-6Al-4V ELI Titanium?

DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against 270 MPa for DMLS AlSi10Mg Aluminum (4.07x).

Which is lighter, DMLS AlSi10Mg Aluminum or DMLS Ti-6Al-4V ELI Titanium?

DMLS AlSi10Mg Aluminum is lighter: 2,670 kg/m³ against 4,400 kg/m³ for DMLS Ti-6Al-4V ELI Titanium.

Which is stiffer, DMLS AlSi10Mg Aluminum or DMLS Ti-6Al-4V ELI Titanium?

DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 72 GPa for DMLS AlSi10Mg Aluminum, so the same part in DMLS Ti-6Al-4V ELI Titanium deflects less under the same load.

Which is lighter for the same job, DMLS AlSi10Mg Aluminum or DMLS Ti-6Al-4V ELI Titanium?

For the same stiffness or strength: DMLS AlSi10Mg Aluminum is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate; DMLS Ti-6Al-4V ELI Titanium is lighter for a strong rod or tie, strong beam, strong panel or plate.

Part that must beDMLS AlSi10Mg AluminumDMLS Ti-6Al-4V ELI Titanium
Stiff rod or tie (tension)lighter8% heavier
Stiff beam (bending)lighter33% heavier
Stiff panel or platelighter43% heavier
Strong rod or tie2.47x heavierlighter
Strong beam1.55x heavierlighter
Strong panel or plate22% heavierlighter

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, DMLS AlSi10Mg Aluminum or DMLS Ti-6Al-4V ELI Titanium?

DMLS AlSi10Mg Aluminum stretches further before it breaks: 10.2% elongation at break against 8.7% for DMLS Ti-6Al-4V ELI Titanium.

Thermal

Which conducts heat better, DMLS AlSi10Mg Aluminum or DMLS Ti-6Al-4V ELI Titanium?

DMLS AlSi10Mg Aluminum conducts heat better: 110 W/m·K against 6.6 W/m·K for DMLS Ti-6Al-4V ELI Titanium.

Which expands less with temperature?

DMLS Ti-6Al-4V ELI Titanium expands less: 9 µm/m·K against 20 µm/m·K for DMLS AlSi10Mg Aluminum.
