Size

3.5 kg Carbon Fiber Extreme Black PETG PRO combines PETG resin with USA-made milled carbon fiber for a deep opaque black, slightly textured finish in a larger spool.

Use a wear-resistant nozzle, 0.40 mm or larger. Start with 240–265°C nozzle and 60–78°C heated bed. Check that your holder accommodates the larger roll and allows it to turn freely.

Try a sample coil or choose the 1 kg spool.

3.5 kg Carbon Fiber Extreme Black PETG PRO: material and uses

This larger-spool PETG PRO combines engineering-grade PETG resin with USA-made milled carbon fiber, rather than carbon powder or dust. It prints deep opaque black with a slightly textured surface. Consider it for rigid prototypes, fixtures and housings where PETG suits the design.

Carbon-fiber reinforcement changes stiffness and surface finish, but does not guarantee impact toughness, heat resistance or warp-free results. Evaluate the printed part against its intended loads, temperature and environment.

Printing 3.5 kg Carbon Fiber Extreme Black PETG PRO

Published nozzle temperature: 240–265°C. Heated bed: 60–78°C. Use a nozzle 0.40 mm or larger. This filament is mildly abrasive; choose a hardened or other suitable wear-resistant nozzle.

Tune flow, retraction, cooling and speed for your printer and geometry. Keep filament dry and store it sealed with desiccant between prints. If drying is needed, follow suitable product and equipment instructions rather than assuming a universal drying schedule.

Larger-spool handling

Check that your holder or rack accommodates the 3.5 kg spool and allows it to rotate freely. Use a smooth feeding path with minimal unnecessary drag. Do not assume this larger roll fits an enclosed feeding system, even if the printer can process the material.

Quality and specifications

Published diameter tolerance, described as combined XY volumetric variation: ±0.02 mm or better. Published roundness (ovality): ±0.02 mm or better. This listing is the 3.5 kg spool option; select the filament diameter appropriate for your printer.

3.5 kg Carbon Fiber Extreme Black PETG PRO FAQ

What does the finish look like?

It prints deep black with no transparency and a slightly textured surface. Appearance varies with lighting, layer height and print settings.

What nozzle should I use?

Use a wear-resistant nozzle, 0.40 mm or larger. Carbon fiber can wear a standard brass nozzle.

What temperatures are listed?

Published starting guidance is 240–265°C nozzle and 60–78°C heated bed. Tune for your printer and build surface.

Will the 3.5 kg spool fit my feeding system?

Check the system’s spool capacity and material requirements. Use a compatible holder that lets the roll rotate freely; do not assume compatibility based on the filament material alone.

Can I try a sample first?
