Carbon Fiber – PETG Filament

Discover the perfect balance of performance and ease of use with ABC3D’s Carbon fiber PETG filament. Produced in Victoria, BC, we’ve blended our premium PETG with high-modulus carbon fiber. As a result, this creates a material perfect for parts that require exceptional stiffness and a superior surface finish.

Stiffness of Carbon Fiber PETG Filament

The key to this filament’s performance is the infusion of 10% milled carbon fiber. This addition dramatically increases the material’s modulus (stiffness). Therefore, it’s ideal for creating rigid, structural components that won’t flex under load. It’s an excellent choice for frames, brackets, and functional prototypes where dimensional stability is critical.

The Printability of PETG

While carbon fiber provides the stiffness, the PETG base makes this material a joy to print. Unlike more demanding engineering materials, our Carbon fiber PETG filament offers excellent layer adhesion, low warping, and superior chemical resistance compared to ABS. Furthermore, it’s designed for high-speed printing, allowing you to create parts faster without sacrificing quality.

Ideal Applications for High-Stiffness Parts

This Carbon fiber PETG filament is specially formulated for applications where stiffness and a great surface finish are the primary concerns. For instance, it’s perfect for drone frames, automotive interior prototypes, and custom tooling. However, for parts requiring extreme impact durability or high wear resistance, we recommend exploring our Nylon-based filaments.

Carbon Fiber PETG Filament: FAQs

1. Is this filament abrasive?

Yes. The carbon fibers are very abrasive. Consequently, this filament will destroy a standard brass nozzle very quickly. You must use a hardened steel, ruby-tipped, or other abrasive-resistant nozzle.

2. How is this different from your PETG/CNT Conductive filament?

This filament is for **structural strength**. The carbon fibers add immense stiffness and rigidity. Our PETG/CNT filament, on the other hand, is for **electrical conductivity**. You choose this Carbon Fiber PETG for strong, rigid parts like drone frames or brackets. You choose PETG/CNT for ESD-safe jigs and enclosures.

3. Why are my Carbon Fiber PETG prints stringy?

This is almost always a moisture issue. In fact, PETG is very hygroscopic, and the carbon fiber additives can make it worse. This moisture turns to steam in the nozzle, causing stringing. To fix this, you must dry the spool at 65°C for at least 4 hours before printing.

4. Do I need an enclosure to print this?

No. An enclosure is not required. Because this carbon fiber PETG filament is based on PETG, it has very low warping. As a result, it prints reliably on open-frame printers as long as you have a good heated bed and proper bed adhesion.
