Carbon-fiber stiffness. Stocked & shipped from our US warehouse.
Rev1 PETG-CF is chopped-carbon-fiber-reinforced PETG — extra stiffness and dimensional stability with a premium matte-black finish for functional, load-bearing parts. Stocked and shipped from Auburn Hills, Michigan; made-to-order sizes ship in 1–3 weeks. Run it through a hardened steel nozzle.

Easy to print like PETG — strong enough to put to work.
PETG is one of the easiest engineering polymers to print — tough, chemical-resistant, and low-warp. Rev1 PETG-CF adds chopped carbon-fiber reinforcement to raise strength 15–30% and boost rigidity and dimensional stability, giving you a premium composite for brackets, housings, fixtures, and functional end-use parts.

Carbon-fiber rigidity — PETG toughness.
A practical composite for parts that have to survive real loads.
Unfilled PETG is tough but flexible. Rev1 PETG-CF locks in stiffness and dimensional stability with chopped carbon fiber while keeping PETG's chemical and moisture resistance — ideal for brackets, housings, fixtures, and functional end-use parts. It prints to a deep matte carbon-fiber black.
The properties that make it an engineering filament.
Meaningfully stronger than ordinary PETG thanks to chopped carbon-fiber reinforcement.
High rigidity with excellent toughness — parts hold their shape under load without going brittle.
Excellent heat resistance and a short processing cycle for reliable, repeatable prints.
Excellent hydrolysis resistance and product stability — holds up around water and humidity.
Machines and finishes cleanly for parts that need post-processing to tolerance.
Prints to a deep matte carbon-fiber black that hides layer lines on visible parts.
Print settings that just work.
Run a touch hotter than plain PETG for strong layer bonding with the carbon-fiber fill.
Good first-layer adhesion on a warm bed; a smooth PEI sheet or light glue aids release.
Carbon fiber is abrasive — use a hardened-steel or wear-resistant nozzle.
Dry the spool before printing to eliminate stringing and get the best surface finish.
Prints reliably on open-frame, heated-bed machines — no enclosure required.
A slightly larger nozzle flows the filled filament smoothly and boosts part strength.
Carbon-fiber PETG for parts that have to perform.
Stiff, strong, heat- and moisture-resistant, and easy to run — PETG-CF is a go-to for functional parts that go into service, not just prototypes.

Rigid, moisture-stable housings.
Enclosures that stay dimensionally stable indoors and out.
PETG-CF's rigidity and hydrolysis resistance make it well-suited to electronics housings, covers, and sealed enclosures that must hold tolerance around humidity and temperature swings.

Tooling that keeps its tolerances.
Stiff, machinable fixtures for the shop floor.
Assembly jigs, fixtures, and workholding that resist flex and wear — and machine cleanly to final tolerance thanks to PETG-CF's good machinability.

Holds up where fluids and chemicals do.
PETG's chemical resistance, reinforced.
Manifolds, ducts, and fluid components that need PETG's excellent chemical and hydrolysis resistance with the added rigidity of carbon fiber.
PETG-CF vs. plain PETG vs. carbon-fiber nylon.

Rev1 PETG-CF — common questions.
Do I need a hardened nozzle?
Yes. The carbon fiber that stiffens this filament is abrasive and will wear out a standard brass nozzle. Use a hardened-steel or other abrasion-resistant nozzle.
How is PETG-CF different from regular PETG?
It's PETG with chopped carbon-fiber reinforcement — 15–30% higher strength and noticeably higher rigidity, with a premium matte-black finish, while keeping PETG's chemical and moisture resistance.
Do I have to dry it?
Drying before printing is recommended for the best surface finish and to eliminate stringing. Keep the spool in a dry box between prints.
Do I need an enclosure?
No — PETG-CF prints reliably on open-frame, heated-bed machines. An enclosure can help on large parts but isn't required.
What sizes and colors are available?
Carbon-fiber black in 1.75 mm, on 1 kg, 2 kg, and 3 kg spools. Pick your spool size in the buy-box; ask us about bulk.
Can Rev1 help me qualify it?
Yes. Tell us the part, loads, and environment and our materials team confirms fit, suggests print settings, and can share the full datasheet.
