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 316L Stainless Steel is 3D printed: its properties depend on build direction and print settings; these are typical values.

Questions

Is Drywall stronger than DMLS 316L Stainless Steel?

DMLS 316L Stainless Steel is stronger: its yield strength is 530 MPa against tensile strength 1.5 MPa for Drywall (353x).

Which is stiffer, Drywall or DMLS 316L Stainless Steel?

DMLS 316L Stainless Steel is stiffer: Young's modulus 185 GPa against 1.5 GPa for Drywall, so the same part in DMLS 316L Stainless Steel deflects less under the same load.

Which expands less with temperature?

DMLS 316L Stainless Steel expands less: 15.7 µm/m·K against 16.7 µm/m·K for Drywall.
