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.

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

Questions

Is DMLS Ti-6Al-4V ELI Titanium stronger than FDM PAHT-CF?

DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against tensile strength 92 MPa for FDM PAHT-CF (12x).

Which is lighter, DMLS Ti-6Al-4V ELI Titanium or FDM PAHT-CF?

FDM PAHT-CF is lighter: 1,060 kg/m³ against 4,400 kg/m³ for DMLS Ti-6Al-4V ELI Titanium.

Which is stiffer, DMLS Ti-6Al-4V ELI Titanium or FDM PAHT-CF?

DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 3.86 GPa for FDM PAHT-CF, 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 Ti-6Al-4V ELI Titanium or FDM PAHT-CF?

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

Part that must beDMLS Ti-6Al-4V ELI TitaniumFDM PAHT-CF
Stiff rod or tie (tension)lighter6.87x heavier
Stiff beam (bending)lighter29% heavier
Stiff panel or plate36% heavierlighter
Strong rod or tielighter2.88x heavier
Strong beamlighter26% heavier
Strong panel or plate20% 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).
