Bambu Lab PC FR in Black is a flame-retardant polycarbonate filament that brings together the outstanding mechanical and thermal properties of PC with UL94 V-0 flame retardancy. This makes it the material of choice for applications where both structural performance and fire safety are mandatory requirements - such as electronics enclosures, control panel housings, electrical junction boxes, and industrial equipment covers. The black colour provides a professional, production-ready appearance straight from the printer.

PC FR requires an enclosed printing environment and elevated temperatures to achieve proper interlayer bonding and minimal warping. On Bambu Lab printers with AMS support, it is compatible with automatic material handling for efficient production runs. Its high glass transition temperature makes finished parts dimensionally stable even in warm electrical enclosures, while the flame-retardant additives ensure the material self-extinguishes without dripping in the event of ignition - a critical safety requirement for CE-marked electrical equipment.

Key features

• UL94 V-0 flame retardancy rating - self-extinguishing without dripping, meeting the standard required for electrical enclosures and industrial equipment.
• High mechanical strength and impact resistance for structural housings and load-bearing components.
• Elevated heat deflection temperature for dimensional stability in warm environments such as electronics enclosures.
• Professional black finish suitable for production parts, electrical housings, and industrial prototypes.
• 1.75 mm diameter for use on Bambu Lab printers and other high-temperature capable FDM systems with enclosure.
• Also available in White for projects requiring a different colour or light-coloured indicator windows.

Compatible with: Bambu Lab X1, X1 Carbon, X1E, P1S (enclosed) and other high-temperature capable FDM printers
