FR from Boston Micro Fabrication (BMF) is a flame-retardant substance created to satisfy the' demanding performance and safety standards of high-temperature applications.
With a UL94 V-0 flammability rating of 2 mm, FR offers exceptional heat resistance, durability, and ease of processing, making it an ideal choice for industries requiring precision and reliability in micro-scale 3D printing.

Why FR?
Flame-retardant materials are essential in sectors such as consumer electronics, aircraft, and micromechanics, where fire safety is a top concern. FR provides:
- High Heat Deflection Temperature (HDT) – The HDT of 160 °C (@0.45 MPa, ASTM D648-07) indicates that FR can withstand high temperatures.
- UL94 V-0 Flammability Rating at 2 mm - Fulfilling important safety requirements for flame-resistant applications.
- Excellent Mechanical Properties - Comprised of impact strength (18 J/m), flexural strength (120 MPa), and tensile strength (68 MPa).
- Easier Handling and Processing - Unlike Loctite 3955, FR is easier to print on and post-process, does not require heating before use, and is still non-solid at room temperature.
- Versatile Compatibility - Specifically designed to work with the microArch S140, S240, S350, and D1025 printers from BMF.
- Multiple Color Options - Transparent yellow and black are available to satisfy various utilitarian and aesthetic requirements.

Applications
FR is perfect for product parts that need to be high-performance, thermal resistant, and flame retardant, such as:
- Brackets, Baffles, and Circuit Board Housings - Electrical insulation and electronics depend on it.
- Consumer Goods and Precision Electronics - When performance and safety are crucial.
- Aerospace and Transportation - Reliable, flame-resistant materials are essential in high-temperature settings.
- Micromechanics and Advanced Manufacturing - Aiming for safety while pushing the boundaries of microfabrication.
With the introduction of FR, BMF pushes the boundaries of high-resolution micro 3D printing by using materials with excellent mechanical qualities, high heat performance, and fire resistance.
FR is a high-performance, user-friendly solution designed for precision applications, not merely a substitute for currently available flame-retardant materials.
