3RDAX™ PETG-CF Carbon Fiber - Box of 8

This filament combines the toughness of PETG with the added strength and rigidity of real carbon fiber. It’s been my go-to for functional parts that need to handle stress without compromising on printability. Compared to standard PETG, it offers noticeably better tensile strength, impact resistance, and layer adhesion—without the hassle of more finicky materials like nylon carbon fiber.

I’ve tested it extensively myself, and what stands out is how easy it is to work with. No heated chamber, no obsessive drying routine—just consistent, reliable results with a matte finish and excellent print quality.

Feedback from customers lines up with my own experience: other PETG-CF filaments don’t quite compare when it comes to strength, surface finish, and smooth extrusion. In fact, this is the only filament I still import—simply because my customers and I haven’t found anything locally that performs at the same level.

If you’re after a material that balances durability and ease of use, this is a solid option. And if you’re unsure, there’s a money-back guarantee—because I stand by it, and so do the people who use it.

I normally have this filament in stock but if I dont, the lead time is 1-2 weeks.

Please get in touch if you wish to try this filament out. I can also offer bulk pricing if you require it.

I have individual rolls availabe here too.
