Formlabs Elastic 50A Resin V2 (FLELCL02), TDS Rev. 01 24.01.2024; parts printed on Form 3, 100 µm, Elastic 50A V2 settings and post-processing; tensile on Die C specimens cut from printed sheets after 3+ h at 23 °C.
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 and SLA Resin Elastic 50A are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is SLS PA12 Nylon stronger than SLA Resin Elastic 50A?
SLS PA12 Nylon is stronger: its tensile strength is 48 MPa against 3.4 MPa for SLA Resin Elastic 50A (14.1x).
Which is lighter, SLS PA12 Nylon or SLA Resin Elastic 50A?
SLS PA12 Nylon is lighter: 930 kg/m³ against 1,010 kg/m³ for SLA Resin Elastic 50A.
Which is lighter for the same job, SLS PA12 Nylon or SLA Resin Elastic 50A?
For the same stiffness or strength: SLS PA12 Nylon is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be
SLS PA12 Nylon
SLA Resin Elastic 50A
Strong rod or tie
lighter
15.3x heavier
Strong beam
lighter
6.34x heavier
Strong panel or plate
lighter
4.08x heavier
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).
Which is more ductile, SLS PA12 Nylon or SLA Resin Elastic 50A?
SLA Resin Elastic 50A stretches further before it breaks: 160% elongation at break against 18% for SLS PA12 Nylon.
