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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Drywall stronger than DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against tensile strength 1.5 MPa for Drywall (733x).
Which is stiffer, Drywall or DMLS Ti-6Al-4V ELI Titanium?
DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 1.5 GPa for Drywall, so the same part in DMLS Ti-6Al-4V ELI Titanium deflects less under the same load.
Which expands less with temperature?
DMLS Ti-6Al-4V ELI Titanium expands less: 9 µm/m·K against 16.7 µm/m·K for Drywall.
