not sourced
Values for
Annealed soda-lime-silica float glass, Pilkington North America Technical Bulletin ATS-129 (04/2025)
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.
SLA Resin Elastic 50A is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Glass stronger than SLA Resin Elastic 50A?
Glass is stronger: its tensile strength is 41 MPa against 3.4 MPa for SLA Resin Elastic 50A (12.1x).
Which is lighter, Glass or SLA Resin Elastic 50A?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 2,500 kg/m³ for Glass.
Which is lighter for the same job, Glass or SLA Resin Elastic 50A?
For the same stiffness or strength: Glass is lighter for a strong rod or tie, strong beam, strong panel or plate.

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).
