The PETG CF filament from The Filament line combines the strength of PETG with 3% carbon fiber for enhanced durability and flexibility. Its advanced formulation prevents nozzle clogging and reduces stringing, ensuring a smooth and hassle-free printing experience, making it suitable for both beginners and experienced users. With a carbon-fiber-like finish, this filament is perfect for creating functional parts that require both strength and visual appeal. Its superior impact resistance and mechanical properties make it ideal for demanding applications such as drone components, racing models, and industrial parts.

Produced entirely in Europe, The Filament’s PETG CF filament helps reduce transport-related emissions while ensuring consistent, high-quality manufacturing. The ReFill format is designed with both user convenience and environmental responsibility in mind. Wound on a sustainable cardboard core, the PETG CF filament is fully compatible with Bambu Lab printer spools and the AMS module, eliminating the need for additional adapters. This spoolless design contributes to reducing plastic waste, promoting eco-friendly 3D printing practices. For those without a Bambu Lab spool, a downloadable spool model is available in the Attachments section to ensure seamless compatibility with the user's printer.

This filament is also available in a standard spool format where the spool is made from recycled plastic. This PETG CF filament from The Filament is easy to work with, featuring a recommended printing temperature range of 230-255 ºC and a heated print bed requirement of 60-70 ºC. Printing speeds between 40-150 mm/s ensure flexibility in project execution. A heated build chamber is not required, making it suitable for a variety of 3D printing setups. More information on the PETG CF filament can be found in the Usage Tips section and in the Attachments section.

Like any 3D printing filament, the The Filament filaments should be stored properly in order to avoid their deterioration and, in consequence, extrusion problems and inferior print quality. The spool can be stored in an airtight plastic bag, in a resealable bag with a desiccant capsule, or in a smart filament container. If the filament has absorbed too much moisture, it must be dried before printing in a filament dryer at 40-50 ºC for about 6 hours.

In order to ensure smooth printing and optimal part quality, the filaments from the The Filament line should be printed in accordance with the settings recommended by the manufacturer in the filaments' technical datasheets.

Adhesion

The filaments from the The Filament line are characterized by ease of printing and great adhesion. Nevertheless, if increased adhesion is needed to prevent warping, adhesion products such as Magigoo, 3DLac or Dimafix are recommended.

Abrasive filament

The PLA CF and PETG CF filaments contain abrasive carbon fibers. This is why it is best to print these materials with a hardened nozzle with a diameter of minimum 0.4 mm to avoid clogging and excessive nozzle wear, and to obtain high quality parts.

Refill format

The filaments that come in Refill format are wound onto an eco-friendly cardboard core which makes them compatible with BambuLab reusable spools. Apart from that, the Refill format is compatible with the Spectrum Refill spools, as well as other adjustable spool holders.
