Bambu Lab PC FR Filament — 1.75 mm, 1 kg

PC FR is Bambu Lab’s flame-retardant polycarbonate. Standard polycarbonate is already one of the toughest, most heat-tolerant materials you can run on a desktop printer — PC FR adds a flame-retardant package that meets the UL 94-2023 V-0 standard, meaning a vertically mounted test specimen self-extinguishes within 10 seconds. That combination makes it the filament to reach for when a part sits near electronics, motors, heaters or mains wiring and a PLA or PETG part simply wouldn’t be appropriate.

It suits electrical enclosures and junction boxes, power-supply and battery housings, machine guards, light fittings, drone and RC components, jigs that live near heat sources, and functional prototypes for engineering, education and small-batch manufacturing. It’s an engineering material rather than a beginner one — if you’re running an enclosed printer and you’re comfortable with ABS or ASA, PC FR is a logical next step.

Key features

UL 94 V-0 flame retardant  High heat resistance (~114 °C Vicat)  High impact strength  ±0.03 mm diameter tolerance  AMS compatible with RFID  3 colours

Works with enclosed Bambu Lab machines (X1 series, P1S, P2S and similar) and any other enclosed printer that can reach 280 °C at the nozzle and 110 °C on the bed. A hardened steel nozzle is recommended — avoid soft brass-only nozzles, which wear faster with engineering materials.

Print settings

• Nozzle temperature: 260–280 °C
• Bed temperature: 90–110 °C
• Chamber temperature: 45–60 °C — an enclosure is strongly recommended to prevent warping and cracking
• Part cooling fan: 0–60% — keep cooling low for maximum layer bonding
• Print speed: up to 300 mm/s; slower perimeters give stronger, cleaner walls
• Retraction: 0.8–1.4 mm at 20–40 mm/s
• Drying: 80 °C for 8 hours in a filament dryer or blast oven (or 90–100 °C for 12 hours on an X1-series heatbed)
• Nozzle: hardened steel recommended; 0.4 mm or larger

If you’re printing on a Bambu Lab machine, select the built-in Bambu PC FR profile in Bambu Studio or Orca and let the RFID tag do the work — it’s the fastest path to a good first print.

Tips from our workshop

Dry it, then keep it dry. Polycarbonate absorbs moisture quickly — faster than most filaments — and wet PC FR prints with popping, stringing, weak layers and a brittle finish. Dry a new or shelf-stored spool at 80 °C for 8 hours before the first print, and run it straight from a dryer or an AMS with fresh desiccant. In humid coastal parts of Australia this makes the difference between a strong part and a disappointing one.

Control the temperature swing. PC FR shrinks as it cools, so tall or wide parts can warp or crack mid-print in an open printer. Keep the enclosure closed, keep the part cooling fan low, use a brim on large footprints and print on a clean textured PEI or engineering plate with a light glue-stick layer for release. And remember the V-0 rating describes flammability under a standard test — it doesn’t make a part suitable for load-bearing or certified electrical use on its own.

Nour Engineering Solutions accepts returns or refunds for change of mind or wrong items ordered within 30 days from the purchase date. Customers need to return the items to Nour Engineering Solutions, ensuring the items are in brand new, unused condition. Customers will also be charged for the cost of the original shipping and a re-stocking fee equal to 10% of the order value.
