AON3D Readyprint™ Carbon Fiber PETG

AON3D Readyprint™ carbon fiber polyethylene terephthalate glycol (PETG) is a composite filament of PETG and chopped carbon fibers. The addition of carbon fiber in PETG offers a significant increase in strength and stiffness along with great printability and dimensional stability, making it an optimum choice for functional prototypes, manufacturing jigs, or end-use parts. PETG complies with RoHS and REACH standards.

Moisture Control

Readyprint™ PETG Carbon is factory pre-dried and should be installed in the Filament Dry Storage and Feed System prior to printing to prevent moisture uptake and minimize the impact of moisture on the printing process. In ambient air, PETG Carbon is mildly susceptible to hydration. It will generally remain printable, but surface finish and seam quality will suffer after prolonged exposure.

If the filament is hydrated, dry filament at 60ºC for 2-4 hours in a convection oven. Ensure drying equipment respects our site requirements to ensure adequate drying performance is achieved. Store filament in air-tight bags or containers alongside silica or zeolite desiccant. Be sure to replace desiccant regularly as its moisture capture ability is exhausted.

For more information, see the Filament Drying and Moisture Control page.

Build Platform Adhesion

For instructions on how to inspect the AON3D build plates, refer to the Clean Build Platform and Build Chamber procedure for AON M2+ or the Inspect and Clean Build Plates procedure for AON-M2 and AON-M2 2020.

Garolite G-10 Build Sheet

PETG Carbon prints best on the Garolite G-10 build sheet due to strong adhesion behavior while at recommended bed temperatures and clean removal once the build sheet is cooled down. The G-10 surface is sensitive to Z offset calibration and scratches or scuffs on the surface. For the best results, use a lower first layer speed, a higher the first layer extrusion temperature, and remove the parts gently after prints are complete to minimize damage on the build surface.

CF-PEEK Composite Plate

PETG Carbon prints well on the CF-PEEK composite plate as it exhibits great adhesion behavior with the highest durability compared to PEI and PC sheets. For best results, ensure that the machine has reached thermal equilibrium before calibrating. If the bed-to-nozzle distance is too small or too large, underextrusion, overextrusion and first layer adhesions issues may occur.

General Process Settings

For best results, process settings should be adjusted based on a particular model geometry. If you require process development support, our Applications Engineering team can help! Send us a message at to consult with one of our Additive Manufacturing Specialists.

Composite material filaments are abrasive.
AON3D recommends using a Extruder Pro and a tungsten carbide nozzle to improve surface finish and reduce component wear. Contact the Customer Success team at to order the assembly.
