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.
1.4305 / UNS S30300, Outokumpu typical values (hot rolled, solution annealed) from 'Steel Grades, Properties and Global Standards'; max service from Carpenter CarTech 303 datasheet
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 is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is SLA Resin Elastic 50A stronger than Stainless 303?
Stainless 303 is stronger: its yield strength is 275 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (80.9x).
Which is lighter, SLA Resin Elastic 50A or Stainless 303?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 7,900 kg/m³ for Stainless 303.
Which is lighter for the same job, SLA Resin Elastic 50A or Stainless 303?
For the same stiffness or strength: Stainless 303 is lighter for a strong rod or tie, strong beam, strong panel or plate.
Part that must be
SLA Resin Elastic 50A
Stainless 303
Strong rod or tie
10.3x heavier
lighter
Strong beam
2.39x heavier

Strong panel or plate
15% heavier
lighter
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).
