ABS with chopped glass fibre: HDT rises to 99 °C at 0.45 MPa and layer lines blur into a matte finish, while notched Charpy collapses from 21.5 to 4.2 kJ/m².

Applications

ABS-GF is suited to rigid housings, tooling and dimensionally stable mechanical components. Glass reinforcement raises modulus and can reduce the warping associated with unfilled ABS. 3DXTech positions FibreX ABS+GF for structural engineering applications, while Bambu’s documented grade also offers a matte surface that visually softens layer lines.

Glass-filled ABS is not interchangeable with tough unfilled ABS. In Bambu’s grade comparison, notched impact resistance falls substantially even as stiffness and heat deflection improve. That favors rigid screwed or supported geometry over thin spring clips and impact-prone tabs. Fiber content and matrix formulation vary between products, and the abrasive reinforcement requires suitable printing hardware.

    3DXTech lists structural engineering uses for FibreX ABS+GF and emphasizes stiffness and reduced printing distortion. This identifies the intended function of that glass-filled grade, not a production case study or universal impact-performance claim.

How to read these values

Values describe representative grades, not every spool. Manufacturer datasheets and independent tests retain their source labels and dates. Printed orientation, test method, conditioning and formulation can change results. Unknown values are —. A listed use is not a certification. Shore A, Shore D and Rockwell hardness are separate scales.
