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.
AISI 1045 cold drawn bar (Niagara LaSalle) for mechanical; Ovako C45 (lists 'SAE 1045' as a similar designation) for physical constants
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 Steel AISI 1045?
Steel AISI 1045 is stronger: its yield strength is 531 MPa against tensile strength 3.4 MPa for SLA Resin Elastic 50A (156x).
Which is lighter, SLA Resin Elastic 50A or Steel AISI 1045?
SLA Resin Elastic 50A is lighter: 1,010 kg/m³ against 7,800 kg/m³ for Steel AISI 1045.
Which is lighter for the same job, SLA Resin Elastic 50A or Steel AISI 1045?
For the same stiffness or strength: Steel AISI 1045 is lighter for a strong rod or tie, strong beam, strong panel or plate.
