SLA Resin Tough 2000 and SLS PA12 Nylon are 3D printed: their properties depend on build direction and print settings; these are typical values.

Questions

Is SLA Resin Tough 2000 stronger than SLS PA12 Nylon?

SLS PA12 Nylon is stronger: its tensile strength is 48 MPa against yield strength 40.4 MPa for SLA Resin Tough 2000 (19%).

Which is lighter, SLA Resin Tough 2000 or SLS PA12 Nylon?

SLS PA12 Nylon is lighter: 930 kg/m³ against 1,090 kg/m³ for SLA Resin Tough 2000.

Which is stiffer, SLA Resin Tough 2000 or SLS PA12 Nylon?

SLA Resin Tough 2000 is stiffer: Young's modulus 1.8 GPa against 1.65 GPa for SLS PA12 Nylon, so the same part in SLA Resin Tough 2000 deflects less under the same load.

Which is lighter for the same job, SLA Resin Tough 2000 or SLS PA12 Nylon?

For the same stiffness or strength: SLS PA12 Nylon is lighter for a stiff rod or tie (tension), stiff beam (bending), stiff panel or plate, strong rod or tie, strong beam, strong panel or plate.

Part that must beSLA Resin Tough 2000SLS PA12 Nylon
Stiff rod or tie (tension)7% heavierlighter
Stiff beam (bending)12% heavierlighter
Stiff panel or plate14% heavierlighter
Strong rod or tie39% heavierlighter
Strong beam31% heavierlighter
Strong panel or plate28% heavierlighter

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 Tough 2000 or SLS PA12 Nylon?

SLA Resin Tough 2000 stretches further before it breaks: 79% elongation at break against 18% for SLS PA12 Nylon.
