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 Copper C110 stronger than SLS PA12 Nylon?
Copper C110 is stronger: its yield strength is 69 MPa against tensile strength 48 MPa for SLS PA12 Nylon (44%).
Which is lighter, Copper C110 or SLS PA12 Nylon?
SLS PA12 Nylon is lighter: 930 kg/m³ against 8,913 kg/m³ for Copper C110.
Which is stiffer, Copper C110 or SLS PA12 Nylon?
Copper C110 is stiffer: Young's modulus 117 GPa against 1.65 GPa for SLS PA12 Nylon, so the same part in Copper C110 deflects less under the same load.
Which is lighter for the same job, Copper C110 or SLS PA12 Nylon?
For the same stiffness or strength: Copper C110 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.
