3D printing filament Flashforge PAHT Carbon Fiber 1.75 mm 500 g

Flashforge PAHT Carbon Fiber 1.75 mm 500 g is a reinforced polyamide high‑temperature (PAHT) 3D printing filament with carbon fiber filler, provided on a 500 g spool for printers that accept 1.75 mm filament. The material combines the toughness and thermal resistance of PAHT with increased stiffness and dimensional stability from dispersed carbon fibers, making it suitable for demanding functional parts, mechanical components and heat‑exposed prototypes.

Advantages

This PAHT carbon fiber filament offers improved stiffness and reduced warping compared with unfilled polyamide, along with higher heat resistance suitable for parts exposed to elevated temperatures. The carbon fiber reinforcement increases dimensional stability and preserves details in printed features. The filament's consistent diameter and spool packaging enable stable feeding on most 1.75 mm extrusion systems when processing parameters are properly set.

Suitable for

• Functional prototypes and end‑use mechanical parts
• Structural components requiring high stiffness and thermal resistance
• Jigs, fixtures and tooling exposed to heat or mechanical load
• Replacement parts for industrial and laboratory equipment

Key specifications

• Material: polyamide high‑temperature (PAHT) with carbon fiber filler
• Nominal diameter: 1.75 mm
• Net weight per spool: 500 g
• Recommended processing: high‑temperature extrusion suitable for PAHT
• Mechanical properties: increased stiffness and improved dimensional stability versus unfilled PAHT
• Thermal behavior: elevated heat resistance appropriate for higher temperature applications
• Surface finish: matte with subtle fiber texture depending on print settings

How to use

Load the 1.75 mm filament onto a compatible extruder and set printer parameters according to your machine's capabilities for high‑temperature polyamide compounds. Use a hardened steel or abrasion‑resistant nozzle to avoid accelerated wear from carbon fibers. Typical settings include higher nozzle and bed temperatures than standard PLA or ABS; enable part cooling minimally or per manufacturer guidance to reduce layer adhesion issues. Ensure good first‑layer adhesion using an appropriate build surface or adhesive, and consider an enclosed chamber or heated build volume to minimize warping during printing.

Usage recommendations

Handle spools in a dry environment and store unused filament in sealed, desiccated containers to prevent moisture uptake. Use hardened tooling and nozzles to prevent abrasion. Calibrate extrusion multiplier and printing temperature on test pieces before producing final parts, and avoid using this filament for food‑contact or high‑electrical‑conductivity applications unless validated.
