FR material achieves UL94V-0 flammability rating at 2.0mm.

Manufacturer of micro-scale 3D printing solutions, Boston Micro Fabrication (BMF), has introduced a new, flame retardant material called FR that’s designed to meet the safety and performance requirements for high-temperature applications.
According to the company, with a UL94 V-0 flammability rating at 2.0mm, FR provides superior heat resistance, durability, and ease of processing—making it suitable for industries that require fire-retardant materials for micro-scale 3D printing applications.
Other notable points of FR include:
- Heat Deflection Temperature (HDT): 160°C (@0.45MPa, ASTM D648-07)
- Mechanical Properties: Tensile strength of 68 MPa, Flexural strength of 120 MPa, and impact strength of 18J/m
- Handling and Processing: FR does not need to be heated before use and remains non-solid at room temperature
- Compatibility: Optimized for use with BMF’s microArch S140, S240, S350, and D1025 printers.
- Color Options: Transparent Yellow or Black
BMF designed FR for product components requiring flame retardancy and high-performance thermal resistance, including
- Brackets, Baffles, and Circuit Board Housings
- Consumer Goods and Precision Electronics
- Aerospace and Transportation
- Micromechanics and Advanced Manufacturing
“At BMF, we’re committed to pushing the boundaries of what’s possible with micro 3D printing,” John Kawola, CEO of Boston Micro Fabrication told engineering.com. “Adding a flame-retardant material to our portfolio gives engineers and designers the ability to 3D print complex, high-resolution parts that also meet critical flame-resistance standards. It’s an important addition for applications where both detail and durability matter.”
