EOS PA 2200 (PA12) Material Data Sheet, process parameter 'Balance' at 120 µm layer thickness, X orientation, dry (conditioned values not given). Live MDS status 04.10.2026, last changed 10.09.2026; PDF via ?topdf=... link on the same page.
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.
SLS PA12 Nylon is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Brass C360 stronger than SLS PA12 Nylon?
Brass C360 is stronger: its yield strength is 310 MPa against tensile strength 48 MPa for SLS PA12 Nylon (6.46x).
Which is lighter, Brass C360 or SLS PA12 Nylon?
SLS PA12 Nylon is lighter: 930 kg/m³ against 8,498 kg/m³ for Brass C360.
Which is stiffer, Brass C360 or SLS PA12 Nylon?
Brass C360 is stiffer: Young's modulus 96.5 GPa against 1.65 GPa for SLS PA12 Nylon, so the same part in Brass C360 deflects less under the same load.
Which is lighter for the same job, Brass C360 or SLS PA12 Nylon?
For the same stiffness or strength: Brass C360 is lighter for a stiff rod or tie (tension); SLS PA12 Nylon is lighter for a stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

For the same stiffness or strength, mass scales with density over stiffness (or strength) raised to a power set by how the part is loaded: 1 for a rod in tension, 1/2 for a beam in bending, 1/3 for a panel (the standard material-selection indices).
