Bambu Lab ABS-GF Filament 1.75mm 1KG – Glass Fiber Reinforced ABS for Engineering Applications
Bambu Lab ABS-GF is a glass fiber-reinforced ABS filament offering superior strength, stiffness, dimensional accuracy, and heat resistance compared to standard ABS. With glass fiber boosting stiffness by over 50% and improving layer strength, ABS-GF is ideal for structural parts, decorative models, and high-performance components that need both function and aesthetic appeal. The fine matte finish with micro-gloss flecks minimizes layer lines.
Perfect for load-bearing parts, mechanical assemblies, functional prototypes, and household tools. Requires enclosed printer and hardened steel nozzle for best results.
Bambu Lab ABS-GF Key Features
- 50%+ Stiffness Increase – Glass fiber significantly boosts rigidity
- Enhanced Dimensional Stability – Reduced warping and deformation
- Higher Heat Resistance – HDT of 99°C vs 87°C for standard ABS
- Fine Matte Finish – Micro-gloss flecks minimize layer lines
- Weather & Wear Resistant – Durable for outdoor and functional use
- AMS Compatible – Works with standard AMS (NOT AMS Lite)

Bambu Lab ABS-GF FAQ
Q: Do I need a hardened steel nozzle?
A: Yes, glass fiber is abrasive and will rapidly wear brass nozzles. Use hardened steel nozzles only.
Q: Is ABS-GF compatible with AMS and AMS Lite?
A: ABS-GF works with the standard AMS system but is NOT compatible with AMS Lite. Use the standard AMS for multi-material printing with ABS-GF.
Q: Why is an enclosure required?
A: ABS materials are prone to warping. The enclosure maintains consistent temperature, and printers like H2/X1E have active chamber temperature control for optimal results.
Q: How does ABS-GF compare to PA6-GF (nylon)?
A: ABS-GF is easier to print (lower temps, less moisture sensitive) while PA6-GF offers better chemical resistance and toughness. Choose based on your application requirements.
Q: Can I print ABS-GF on an open printer?
A: An enclosure is highly recommended. Open printers may produce parts with warping and poor layer adhesion.
