3D printing filament BambuLab PC FR 1.75 mm 1 kg with reusable spool — Gray

BambuLab PC FR 1.75 mm is a flame‑retardant polycarbonate filament supplied on a reusable 1 kg spool and intended for FFF/FDM 3D printing. The material combines the high heat resistance and mechanical strength of polycarbonate with an added flame‑retardant formulation, making it suitable for functional parts, housings and prototypes where improved thermal performance and reduced flammability are required. The filament diameter is 1.75 mm and the product is presented in a gray color for neutral, industrial-looking prints.

Advantages

The filament offers elevated heat resistance and good impact strength typical of polycarbonate, while its flame‑retardant formulation reduces the risk of ignition in applications where fire safety is a consideration. Supplied on a reusable spool, it supports convenient storage and reduces waste. The consistent 1.75 mm diameter and controlled manufacturing tolerances enable reliable extrusion and dimensional stability for functional parts.

Suitable for

• Functional parts and mechanical components requiring high heat resistance
• Enclosures, housings and electrical covers with fire‑safety requirements
• Prototypes and end‑use parts that need improved impact strength
• Applications where a neutral gray finish is preferred for assemblies

Key specifications

• Material: flame‑retardant polycarbonate (PC FR)
• Diameter: 1.75 mm
• Net filament weight: 1 kg (on reusable spool)
• Color: Gray
• Form: Solid filament for FFF/FDM 3D printers

How to use

Load the 1.75 mm filament into a compatible FFF/FDM 3D printer configured for high‑temperature thermoplastics. Recommended print settings typically include a heated build plate and a hotend temperature appropriate for polycarbonate materials; start with manufacturer guidance for polycarbonate and adjust based on print quality. Ensure good bed adhesion—use of a suitable build surface, adhesive aid or enclosure is advised to reduce warping. Post‑processing such as annealing may be applied where dimensional stability and strength require further improvement.

Usage recommendations

Use printers capable of reaching and maintaining the higher extrusion temperatures required for polycarbonate; operate in a well‑ventilated area and follow safety guidelines for flame‑retardant materials. Store the filament on its reusable spool in a dry environment to avoid moisture uptake and retain print performance.
