Product Details
- Incredible strength and durability: SainSmart Carbon Fiber PETG Filament is super-strong, perfect for printing items that require added strength. It’s more abrasive than standard PETG, providing higher rigidity and strength. With its toughness, wear resistance, and tear resistance, this filament is built to last.
- Wide industrial applications: This filament is perfect for a variety of industrial applications, from aerospace to engineering to motorsports. Its versatility makes it a go-to choice for professionals in a wide range of fields.
- Better dimensional stability: Say goodbye to warping and hello to smooth, warp-free prints. SainSmart Carbon Fiber PETG Filament offers excellent layer adhesion and easy support removal, ensuring that your prints come out looking their best every time.
- Excellent mechanical properties: Filled with 10% Carbon Fiber combined with 90% PETG, this filament is designed to provide high-quality prints with ease. Its excellent material proportioning ensure that your prints are not only strong and durable, but also easy to print.
- [Tip]: Carbon Fiber PETG filament can be a bit trickier to print with than PLA or normal PETG, but don’t worry! Here are some tips to help you succeed: Use a larger, abrasion-resistant steel nozzle (0.4mm or more) and keep it clean to prevent clogging. Dry the filament before printing and use an enclosure to maintain a constant ambient temperature for best results. Print at 220°C-260°C with a bed temperature of 70°C-100°C, and print speed of 40-60mm/s.

Printing SainSmart PETG-CF
SainSmart PETG-CF in Bronze is PETG filled with chopped carbon fiber, and this listing is a 1kg spool. The fibers make parts stiffer and more dimensionally stable than plain PETG, but they are abrasive, so a hardened nozzle is mandatory (see nozzle compatibility below). The ranges below are for PETG-CF, which usually prints a little hotter than plain PETG. PETG-CF is best suited to stiff functional parts such as jigs, fixtures and brackets that need PETG's chemical resistance. Brands and even individual spools vary, so treat these as starting points and run a quick temperature tower to lock in the sweet spot for your printer.
Ranges checked against Bambu Lab, Prusament and Polymaker data. Heat resistance is the heat deflection temperature (HDT). Read our carbon fiber filament guide for bed adhesion, drying, troubleshooting, and material-specific tips.
Nozzle Compatibility
Carbon fiber is abrasive and wears brass (and stainless) nozzles out of round, sometimes within a single spool. Use hardened steel or another wear resistant nozzle such as ruby or tungsten carbide. With hardened steel, start about 5 to 10°C hotter than you would with brass.
