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.

Questions
Is DMLS Ti-6Al-4V ELI Titanium stronger than Wood?
DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against tensile strength 99 MPa for Wood (11.1x).
Which is stiffer, DMLS Ti-6Al-4V ELI Titanium or Wood?
DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 12.5 GPa for Wood, so the same part in DMLS Ti-6Al-4V ELI Titanium deflects less under the same load.
Which conducts heat better, DMLS Ti-6Al-4V ELI Titanium or Wood?
DMLS Ti-6Al-4V ELI Titanium conducts heat better: 6.6 W/m·K against 0.18 W/m·K for Wood.
Which expands less with temperature?
Wood expands less: 3.8 µm/m·K against 9 µm/m·K for DMLS Ti-6Al-4V ELI Titanium.
