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 SLA Resin Standard 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 SLA Resin Standard?
DMLS Ti-6Al-4V ELI Titanium is stronger: its yield strength is 1,100 MPa against tensile strength 60 MPa for SLA Resin Standard (18.3x).
Which is stiffer, DMLS Ti-6Al-4V ELI Titanium or SLA Resin Standard?
DMLS Ti-6Al-4V ELI Titanium is stiffer: Young's modulus 110 GPa against 2.75 GPa for SLA Resin Standard, so the same part in DMLS Ti-6Al-4V ELI Titanium deflects less under the same load.
