Formlabs Clear Resin V5 (FLGPCL05), TDS Rev. 01 March 20, 2024; printed on Form 4 at 100 µm, washed 5 min in >=99% IPA, post-cured 15 min at 60 °C in Form Cure. Orientation not stated.
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 Standard is 3D printed: its properties depend on build direction and print settings; these are typical values.
Questions
Is Rubber stronger than SLA Resin Standard?
SLA Resin Standard is stronger: its tensile strength is 60 MPa against 23 MPa for Rubber (2.61x).
Which is more ductile, Rubber or SLA Resin Standard?
Rubber stretches further before it breaks: 830% elongation at break against 8% for SLA Resin Standard.
