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 Plywood?
DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against tensile strength 41.4 MPa for Plywood (26.6x).
Which is stiffer, DMLS Ti-6Al-4V ELI Titanium or Plywood?
DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 7.45 GPa for Plywood, 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 Plywood?
DMLS Ti-6Al-4V ELI Titanium conducts heat better: 6.6 W/m·K against 0.12 W/m·K for Plywood.
Which expands less with temperature?
Plywood expands less: 3.8 µm/m·K against 9 µm/m·K for DMLS Ti-6Al-4V ELI Titanium.
