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 AlSi10Mg Aluminum and SLA Resin Standard are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is DMLS AlSi10Mg Aluminum stronger than SLA Resin Standard?
DMLS AlSi10Mg Aluminum is stronger: its yield strength is 270 MPa against tensile strength 60 MPa for SLA Resin Standard (4.5x).
Which is stiffer, DMLS AlSi10Mg Aluminum or SLA Resin Standard?
DMLS AlSi10Mg Aluminum is stiffer: Young's modulus 72 GPa against 2.75 GPa for SLA Resin Standard, so the same part in DMLS AlSi10Mg Aluminum deflects less under the same load.
