Carbon fiber filament

Carbon fiber filament

Carbon fiber filaments containing carbon powder or short fibers are quite common in 3D printing. Adding these carbon fibers to your 3D printing filaments naturally brings high rigidity and gives your objects a beautiful matte black finish.

Composite fillers are integrated into different types of plastic. Commonly used base materials include PETG and nylon, chosen for their strength and general toughness.

Carbon fiber filament: benefits and composition

The amount of carbon fiber added directly affects performance. Typically, the carbon filler is present in low concentrations in ABS matrices (<10%). This is enough to significantly improve performance and printability of your ABS filament.

Indeed, common ABS printing issues like warping are eliminated thanks to the stabilization provided by carbon fibers. Result: no warping, better rigidity, a clean, professional finish, and excellent layer bonding. The Nanovia Carbon ABS filament is a great example of such quality.

In PETG and nylon matrices, carbon content can be higher—typically between 15 and 25%.

Carbon fiber is also very useful for enhancing nylon filament printability. Normally prone to shrinkage and warping, carbon nylons do not suffer from these issues and offer even higher strength and rigidity. These PA CF (Carbon Fiber) filaments rank among the most durable and high-performance 3D printing materials, alongside glass fiber-reinforced options.

The technical performance of these carbon composite filaments expands additive manufacturing capabilities. Compatible with most professional desktop 3D printers, they are abrasive and require a hardened nozzle (steel or ruby) of at least 0.5 mm diameter.

Why choose carbon fiber filaments?

High rigidity, impressive strength-to-weight ratio, visual appeal, and ease of printing—if these qualities are what you seek, carbon filaments are for you. Choose the Forshape PETG Carbon for great chemical resistance, Carbon ABS for temperature resistance, or Polymaker Fiberon PA6 CF20 for outstanding mechanical performance and durability.

Which carbon composite filament brand to choose?

Technical carbon filaments require precise manufacturing. It’s crucial to buy them from reputable manufacturers. Consistent filler load, uniform and well-oriented dispersion are key to a high-quality carbon composite filament. Choose brands known for their expertise and manufacturing excellence.
