Below is data about the mechanical properties of selected Formlabs SLA resins. Use this data along with the information in Choosing the right material and the technical data sheet (TDS) for your selected material to pick a resin and evaluate your printed parts. If data for your material is not available, choose the closest comparable material and interpolate or extrapolate as necessary. For other requests, reach out to Formlabs Support or your sales representative.

Samples were printed on a Form 3 printer, post-cured as recommended for each material, and conditioned at 23 ℃ and 30% relative humidity for 48 hours.
