Phrozen Engineering Flame Retardant FR940 Resin is a purpose-built, engineering-grade material designed for functional parts that must endure real-world conditions while prioritizing fire safety. Built for engineers, designers, and makers who demand consistent, reliable results, FR940 combines mechanical performance with flame-retardant properties to support safer prototypes and final parts.
Why FR940 stands out
In a crowded market of general-purpose resins, FR940 is purposefully formulated to deliver repeatable prints with validated Phrozen settings. This means less trial-and-error, fewer failed builds, and tighter tolerances on every layer. The resin’s flame-retardant characteristics help address applications where fire safety considerations matter—without sacrificing the strength and precision you expect from an engineering resin.
Phrozen quality you can trust: FR940 is part of Phrozen’s engineering resin line, backed by a brand known for dedicated, developer-focused formulations. The resin is designed to work seamlessly with Phrozen LCD 3D printers and compatible 405nm systems, ensuring you get predictable results across your equipment.
Key benefits
- Reliable print quality with validated settings for Phrozen printers, reducing setup time and improving batch consistency.
- Flame retardant performance with self-extinguishing properties, supporting safety-focused parts and assemblies.
- 405nm compatibility verified to work across Phrozen LCD 3D printers and other 405nm resin systems, making it a versatile choice for mixed workflows.
- Engineering-grade material designed for functional prototypes and real-world components rather than purely cosmetic models.
Ideal use cases
FR940 is well-suited for parts that must perform under load, resist wear, and meet fire-safety considerations. Think of short- to mid-run engineering prototypes, non-structural housings, test fixtures, and functional components that benefit from a flame-retardant profile. Designers can iterate quickly on enclosures, mounts, and mechanical interfaces while maintaining reliable print behavior and surface quality.
What problems FR940 solves
- Unpredictable prints and delaminations common with generic resins are reduced thanks to Phrozen’s validated printing profiles.
- Safety concerns when fire risk is a consideration are addressed with a resin that offers flame-retardant properties suitable for many engineering environments.
- Workflow friction from mixing resins or juggling incompatible materials is minimized by a resin designed to partner with Phrozen printers and 405nm ecosystems.
Printing and workflow notes
For best results, follow the Phrozen Resin Guide and the FR940-specific recommendations within the Phrozen Resin User Guide. While FR940 is optimized for Phrozen printers, its 405nm compatibility also makes it a solid option for other compatible 405nm systems. Post-processing—curing and washing—should align with standard Phrozen practices to maximize dimensional accuracy and surface finish.
What makes FR940 different from other resins
FR940 doesn’t just offer a flame-retardant claim; it combines that safety feature with engineering-grade performance. This means you get parts that hold tight tolerances, resist wear, and print consistently across batches. The result is a resin that supports practical, production-minded prototypes and components without compromising on safety or reliability.
Who should consider FR940
FR940 is an excellent fit for design engineers, product developers, and fabrication shops working on real-world components where both mechanical performance and flame retardancy matter. It’s also a strong option for education or R&D environments where safety criteria need to be demonstrated in test fixtures and functional prototypes.
Explore the FR940 resin today to elevate your engineering workflows with a resin that aligns print reliability, flame retardancy, and 405nm compatibility into a single, purpose-built solution from Phrozen.
