The Benefits of Using Flame Retardant Resin
Accelerated Production Lead Times
Producing flame-retardant parts with SLA 3D printing can substantially reduce lead times compared to traditional manufacturing processes. How? By eliminating many processing steps. For example, polyurethane casting involves the following:
- 3D printing or machining a mold pattern
- Construct silicone mold
- Find a UL-rated polyurethane material
- Pour into mold
- Extract casted part, which most of the time is a tedious work
- Post-processing
With Formlabs Flame Retadardant resin, the manufacturing workflow is as easy as any other polymer part. Open the digital model in Formlabs’ PreForm software Select the resin and desired layer thickness Orient to preserve fine details Generate Supports Send to print.
A Halogen-Free Material
Specifically Formulated for:
- Transportation
- Aviation
- Manufacturing
- Electronics
- Medical and
- Aerospace industries
Look and Feel of Injection Molded Parts
Fabricate self-extinguished plastic parts that have a great surface finish and are far superior to other 3D printing technologies, such as FDM 3D printing.
Applications
Produce certified flame retardant, UL 94 V-0, and FAR-rated 3D-printed parts that meet the certification requirements for enduring hazardous environments.
Aviation
Interior parts in airplanes, automobiles, and railways with excellent surface finish
Electronics
Protective and internal consumer or medical electronics components
Manufacturing
Custom jigs, fixtures, and replacement parts for industrial environments with high temperatures or ignition sources

FORM CURE SETTINGS
DURATION TEMPERATURE
60 minutes 70 °C
NOTES
- To achieve the highest HDT of 111 °C @ 0.45 MPa: Post-cure parts in Form Cure for 120 min at 80 °C.
- For applications that do not require the maximum heat resistance but offer more toughness, post-cure parts in Form Cure for 60 min at 70 °C.

*Material properties may vary based on part geometry, print orientation, print settings, temperature, and disinfection or sterilization methods used. Data for tensile samples were measured on Type I tensile bars printed on a Form 3+ printer with 100 µm Flame Retardant Resin settings, washed in a Form Wash for 10 minutes in ≥99% Isopropyl Alcohol, and post-cured at 70°C for 60 minutes or 80°C for 120 minutes in a Form Cure.
