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.
SLA Resin Elastic 50A and SLS PA12 Nylon are 3D printed: their properties depend on build direction and print settings; these are typical values.
Questions
Is SLA Resin Elastic 50A stronger than SLS PA12 Nylon?
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, SLA Resin Elastic 50A or SLS PA12 Nylon?
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, SLA Resin Elastic 50A or SLS PA12 Nylon?
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

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, SLA Resin Elastic 50A or SLS PA12 Nylon?
SLA Resin Elastic 50A stretches further before it breaks: 160% elongation at break against 18% for SLS PA12 Nylon.
