ABS-GF - Bambu Lab

The Bambu Lab ABS-GF is an ABS filament reinforced with glass fiber that outperforms standard ABS in stiffness, thermal resistance, and dimensional stability. It is designed to minimize warping and deformation, even in complex structures or parts with demanding geometries. It features a fine matte finish that hides layer lines and provides a more uniform appearance, ideal for both mechanical components and decorative parts.

This material offers mechanical and physical properties suitable for demanding applications:

To achieve optimal performance with ABS-GF, it is recommended to follow proper printing practices. The filament should be dry before printing (e.g., 80 °C for about 8 hours), and humidity should remain below 20 % to prevent defects such as poor layer adhesion or brittleness. Using hardened nozzles of recommended diameters like 0.4 mm, 0.6 mm, or 0.8 mm improves durability when working with abrasive material such as glass fiber.

Ideal settings involve multiple adjusted parameters:

• Extrusion temperature between 240–270 °C.
• Type of rigid heated bed or plates like Engineering / High Temperature / Textured PEI, with bed at 80–100 °C and adhesive if needed.
• Moderate speeds, ideally below 180 mm/s to maintain precision, especially for parts with high infill density.
• Use of a printer with enclosure to maintain stable ambient temperature, avoid drafts, and reduce warping.
• Adjusted ventilation, with layer fan at low percentage to avoid sudden cooling that compromises layer adhesion.

This filament is particularly suitable for functional parts that require water resistance, continuous mechanical stress, light load supports, enclosures, structural components, connectors, molds, and objects for prolonged or demanding environments. It is also useful for users who want an aesthetic finish but need more rigidity than standard ABS.

Despite its strengths, ABS-GF has some considerations: it may emit odor during printing, requires a printer with a closed enclosure to prevent deformation, is not compatible with very fine nozzles (e.g., 0.2 mm), and its glass fiber content makes it more abrasive, so a hardened nozzle is recommended. However, if parameters are correctly set and the proper equipment is used, Bambu Lab ABS-GF is an excellent choice for users seeking high-performance, durable, and professional-quality filament for advanced home use, professional applications, and light industrial purposes.
