Important: Flame and mechanical performance depend on the validated wash + post-cure workflow. Follow the manufacturer documentation for the correct process and settings.

Certified self-extinguishing parts — without the tooling lead time

Formlabs Flame Retardant Resin is a specialty, halogen-free material designed to create self-extinguishing parts for indoor and industrial environments with high temperatures or potential ignition sources. Produce functional components with the geometric freedom of SLA — ideal for custom housings, covers, mounts, clips, and protective parts.

Alongside flame performance, the material is engineered for stiffness, heat resistance, and low creep so parts maintain shape and function over long periods of use.

Why Choose Formlabs Flame Retardant Resin?

UL 94 V-0 Certified

Create parts for applications where flame performance is a requirement — supporting safety-focused design without traditional tooling delays.

Stiff, Heat-Resistant Parts

Engineered for rigidity and heat exposure so parts can perform in warm environments or near ignition sources.

Low Creep for Long-Term Use

Designed to resist deformation over time — helpful for mounts, brackets, and enclosures that must hold geometry.

Iterate Fast, Produce On Demand

Ideal for bridging the gap between prototype and production, enabling fast design revisions and small-batch manufacturing.

Applications

Flame Retardant Resin is suited to functional parts used indoors or in industrial settings where heat and safety standards are key.

Consider Flame Retardant Resin for:

  • Electrical housings, protective covers, and guards
  • Mounts, brackets, clips, and retention features in warm environments
  • Custom ducting, shrouds, and airflow management parts near heat sources
  • Industrial fixtures where stiffness and long-term dimensional stability matter

Tip: Use the validated print settings and post-cure cycle from the documentation to achieve the certified performance.

Workflow Overview

Flame Retardant Resin follows a standard print + wash + post-cure workflow. For safety-rated applications, follow the validated process in the documentation.

  • Print using the manufacturer preset for Flame Retardant Resin.
  • Wash per the validated wash method and timings.
  • Post-cure per the validated cycle to reach intended flame and mechanical performance.
  • Finish (support removal, light deburr) while maintaining the critical surfaces/features your application requires.
