Bambu Lab PLA-CF Filament 1.75mm - 1kg - Includes Reusable Spool Twilight Blue

Premium Carbon Fibre-Reinforced PLA for Strong, Sharp Prints

Discover a filament that bridges the gap between practicality and performance. Bambu Lab PLA-CF blends the ease of standard PLA with the rigidity and refined finish of carbon-fibre composite materials. Whether you're creating functional engineering parts or stylish display pieces, this material lifts your printing game. 

Key Features

• Reinforced with carbon fibres to significantly improve stiffness, bending strength and modulus compared to regular PLA. 

• Maintains the printability and beginner-friendly nature of standard PLA—so you get advanced mechanics without advanced headaches. 

• Produces a matte surface finish with nearly invisible layer lines, giving your prints a premium, industrial look. 

• Engineered to offer low shrinkage and excellent dimensional stability, making it ideal for parts that must fit or align precisely. 

• Compatible with the Bambu Lab Automatic Material System (AMS) and high-speed printing environments with low clog risk. 

• Comes in multiple attractive colour options including Burgundy Red, Matcha Green, Lava Gray, Jeans Blue, Black, Royal Blue, Iris Purple.

Technical Details 

• Filament diameter: 1.75 mm (±0.03 mm) 
• Spool weight: 1 kg 
• Recommended printing settings: Nozzle temperature: ~210 °C to 240 °C - Bed temperature: ~35 °C to 45 °C (depending on build plate) 
• Mechanical properties (typical): Bending strength (XY): ~89 MPa vs ~53 MPa for standard PLA. - Bending modulus (XY): ~3950 MPa vs ~2360 MPa for standard PLA. 
• Density: ~1.22 g/cm³ 

What Makes PLA-CF Great?

If you're printing parts that need to look good and perform well—such as brackets, structural prototypes, tech enclosures or decorative pieces with a refined aesthetic—PLA-CF stands out. It gives you:

• Improved mechanical strength while keeping print-setup simple.
• A refined matte finish that hides layer lines and lends a premium feel.
• Compatibility with advanced print setups without demanding drastic workflow changes.

Recommended Use & Tips

• Use with a hardened steel or wear-resistant nozzle (due to carbon fibre content). 

• Dry filament before use if stored in humid conditions: ~55 °C for 8 hours suggested. 

• Keep printing speed under ~200 mm/s for best results.

• Pair it with PLA Basic or other PLA series materials for colour accents with the same mechanical base. 

• Use build plates recommended for composite filaments: e.g., textured PEI, high-temperature plate, cool plate versions.
