An ideal choice to experience a reliable carbon fiber composite printing for strong and cost-effective end-use applications

Raise3D Industrial PET CF is a carbon fiber-reinforced composite filament based on PET (Polyethylene terephthalate). Well-dispersed 15wt% carbon fibers enhance the rigidity, strength, heat and chemical resistance of the PET matrix. After annealing, PET CF stabilizes its heat resistance at around 150ºC and tensile modulus and strength of over 6 GPa and 80 MPa respectively. Compared to carbon fiber-reinforced Nylon filament, the high printability, dimensional stability, high creep resistance and low moisture absorption makes PET CF an ideal choice for reliable carbon fiber composite printing for strong and cost-effective end-use applications, such as jigs. fixtures, functional parts.

• HDT up to 150℃
• Strong and high stiffness
• High dimensional stability
• Low moisture absorption
• Creep and chemical resistance

Printing Guide

Recommended Print Settings

• Nozzle temperature (°C): 280-300℃
• Bed temperature (°C): 60-80℃
• Layer height (mm): 0.1-0.25 mm
• Printing speed (mm/s): 35-90 mm/s
• Cooling fan: On
• Drying temperature (°C): 70-80°C for 8 to 12 hours

Printing Note:

• Dry PET CF at 70-80°C for 8-12 hours before printing, as low moisture content is crucial for final printed part quality.
• After drying, we recommend storing PET CF filaments inside Raise3D Filament Dry Box during the printing process.
• Abrasion of the brass nozzle happens frequently when printing PET CF. Using an abrasion-resistant nozzle, at minimum a Steel nozzle should be used or preferably, a SiC nozzle.
• After printing, it is recommended to anneal the model in an oven at 80-100°C for 8-12 hours.
• For a small size model (side length < 50 mm), annealing at 80°C for 8 hours is recommended; For a medium-size model (50 mm < side length < 150 mm), annealing at 80°C for 12 hours is recommended; For a large size model, 100°C for at least 12 hours is recommended.
• If PET CF is also used as the support material, please remove the support structure after annealing.
