From€301.29incl. 21% BTW
Flame Retardant Resin is a specialty UL 94 Blue Card-certified material for creating self-extinguishing and halogen-free parts with favorable flame, smoke, and toxicity (FST) ratings. Use FR Resin to easily 3D print flame-retardant, heat-resistant, stiff, and creep-resistant parts that will perform well long-term in indoor and industrial environments with high temperatures or ignition sources.
Tests and certifications include: UL 94 V-0 at 3 mm thickness for flammability; FAR 25.853 Appendix F, Part I for flammability; and ASTM E662 for FST. For full test results and certifications, see the Technical Data Sheet.

Post-Processing
Washing
The foundational step in any SLA post-processing workflow is to remove any excess resin on the surface of the parts through an alcohol or ether wash.
SETTINGS
Curing
Post-curing Engineering and Specialty Resins is essential for parts to achieve their full strength and functionality. This step completes the chemical reaction initiated during printing, transforming the part from its green state into a fully finished component.

FAQ
Flame Retardant Resin is UL 94 Blue Card-certified at V-0 rating (tested at 3 mm thickness) and meets FAR 25.853 Appendix F, Part I flammability standards for aviation applications. It also carries an ASTM E662 rating for flame, smoke, and toxicity (FST). Full test results and certifications are available in the Technical Data Sheet.
Yes. Flame Retardant Resin is a halogen-free material, making it suitable for applications where halogen-free compliance is a regulatory or safety requirement.
When post-cured at 100 °C for 10 minutes after a 5 minute preheat in Form Cure or Form Cure L, Flame Retardant Resin achieves a tensile modulus of 3.1 GPa, ultimate tensile strength of 41.2 MPa, flexural strength of 75 MPa, and a heat deflection temperature of 111 °C at 0.45 MPa. It is designed to be stiff, creep-resistant, and heat-resistant for long-term performance in demanding environments.
Yes. The material is stiff and functional enough to support post-fabrication operations including tapping, trimming, and drilling.
Flame Retardant Resin is well-suited for interior parts in airplanes, automobiles, and railways; custom jigs, fixtures, and replacement parts for industrial environments with high temperatures or ignition sources; and protective or internal components for consumer and medical electronics. Its certifications make it a practical choice wherever FST compliance is required.
Parts printed in Flame Retardant Resin feature an exceptional surface finish and high dimensional accuracy that are far superior to FDM 3D printing, with an XY resolution of 25 microns. The result closely resembles the look and feel of injection-molded plastic parts.
Post-processing involves two main steps. First, wash the part using isopropyl alcohol or an ether-based solution to remove uncured resin from the surface. Formlabs Form Wash or Form Wash L are both compatible. Second, post-cure the part using a Form Cure or Form Cure L unit. Post-curing is essential for parts to achieve their full strength and intended functional properties by completing the chemical reaction initiated during printing.
Wash time settings are available on the Formlabs support site for Form Wash and Form Wash L. Cure settings are available separately for Form Cure V1, Form Cure V2, Form Cure L V1, and Form Cure L V2.
Yes. Formlabs will ship a 3D printed Flame Retardant Resin sample part directly to your office so you can evaluate the material quality and surface finish firsthand. Request a sample part.
