IIID Max – FiberX ABS+CF Filament

IIID Max – FiberX ABS+CF Carbon Fiber Filament

The FiberX ABS+CF combines the heat resistance and acetone-smoothing capability of ABS with the stiffness and dimensional stability of carbon fiber reinforcement. The result is a filament that produces parts rivaling injection-molded engineering plastics — stiff, heat-resistant, lightweight, and with a professional matte black finish. Originally $69.99, now $39.99 — a 43% discount.

Where Carbon Fiber PLA+ maxes out at ~60°C heat deflection, ABS+CF handles temperatures up to 100°C while maintaining its rigidity. This makes it ideal for parts near heat sources, in automotive applications, and in industrial environments where PLA-based materials would soften and fail.

Key Specifications

ABS+CF vs. Carbon Fiber PLA+ vs. PA6/66+CF15

CF PLA+ ($35.99): Easiest to print, lowest heat resistance (~60°C). Best for lightweight rigid parts at room temperature. ABS+CF ($39.99): Mid-range difficulty, good heat resistance (~100°C), acetone-smoothable. Best for functional parts near heat. PA6/66+CF15 ($35.90): Hardest to print, highest performance (~200°C), maximum toughness. Best for industrial and engineering applications.

Pro Tips

Use hardened steel nozzle at 0.5mm or larger. Enclosed printer strongly recommended — ABS+CF warps more than standard ABS due to the carbon fiber content. Print at 250°C nozzle, 100°C bed. The carbon fiber matte finish can be acetone-smoothed for a unique semi-gloss textured look that no other material can replicate. Apply acetone vapor lightly — the CF texture becomes more visible as the ABS matrix smooths around the fibers.

Best Applications

Automotive brackets, heat-resistant enclosures, industrial tooling, jigs and fixtures, electronics housings near heat sources, RC vehicle parts, structural drone components, and any part needing the combination of heat resistance, stiffness, and a professional matte finish.
