Bambu Lab ABS-GF 1.75mm Filament - 1kg with Spool Grey

Product Overview

• ABS-GF is a glass fibre reinforced ABS filament developed by Bambu Lab.
• Compared with standard ABS, it offers improved strength, stiffness, heat resistance, and dimensional stability (less warping/deformation) thanks to the glass fibre reinforcement. 
• Offers a matte finish with a subtle micro-gloss (blurs layer lines) owing to the glass fibres.
• Suited for both mechanical/functional parts (load-bearing, high temperature) and decorative objects (good finish + vibrant colours) thanks to its properties. 

Key Specifications

• Filament diameter: 1.75 mm.
• Spool net filament weight: 1 kg. 
• Density: ~ 1.08 g/cm³. 
• Vicat softening temperature: ~ 103 °C.
• Heat deflection temperature (0.45 MPa): ~ 99 °C. 
• Melting temperature: ~ 202 °C. 
• Recommended printing nozzle temperature: ~ 240-280 °C. 
• Recommended bed temperature: ~ 80-100 °C. 
• Printing speed: typically < 180 mm/s for best results (enclosure strongly recommended). 

Features & Benefits

• High strength & stiffness: The glass fibre reinforcement gives notably higher bending modulus and bending strength compared to standard ABS. 
• Improved dimensional stability: Less warping and deformation, making it more reliable for functional parts and assemblies. 
• Durability & water-resistance: Retains ABS benefits (water resistance, wear resistance) plus the enhanced mechanical traits. 
• Matte aesthetic finish: The glass fibre gives a smooth surface, concealing layer lines and giving parts a nice look. 
• High temperature capability: With heat deflection near ~99 °C, it's more viable for higher temp applications than regular ABS. 

Available Colours

ABS-GF is available in the following colours:

• White (41100)
• Grey (41102)
• Orange (41300)
• Red (41200) 
• Blue (41600) 
• Black (41101) 

Printing Considerations & Tips

• Use an enclosed print chamber (recommended) to reduce warping and ensure stable temperature.
• Dry filament before use (e.g., 80 °C for ~8 hours) to reduce moisture-related defects such as poor layer adhesion. 
• Bed surface prep: use a high temp plate, textured or smooth PEI, with adhesive (glue) recommended.
• Because of the glass fibres, use a hardened steel nozzle (or nozzle compatible with abrasive filaments) to manage wear. 
• Printing speed: although capable of relatively high speed, to maintain part quality < 180 mm/s is advised.
• The matte finish is a benefit, but you may still need to post-process (sanding, sealing) depending on final application.

Ideally Used For

• Users printing functional or mechanical components that require higher stiffness or temperature resistance.
• Users needing aesthetic parts with good finish, where layer lines are less visible but material strength matters.
• Users working with the Bambu Lab ecosystem (spools, RFID recognition, compatibility with AMS) for ease of use.

Please Note:

• Like many ABS and fibre-reinforced materials, increased warp risk remains: proper bed adhesion, enclosure, and drying are important.
• Fumes: ABS and reinforced ABS can produce stronger odour during printing—ensure good ventilation. 
• Glass fibre content makes the filament more abrasive: Nozzles wear faster unless using hardened or wear-resistant tooling.
• Cost may be higher than standard ABS; spool management (drying, storage) is more critical due to fibre reinforcement.
