Phaetus aeForce PET-CF — 15% Carbon Fiber Reinforced PET, 1.75mm, 1kg
A carbon-fiber-reinforced PET engineering filament for functional, load-bearing parts. The PET base brings low moisture sensitivity (relative to nylon), high strength, creep resistance, good chemical resistance and high heat resistance; the 15% chopped carbon fiber adds stiffness and a matte finish while suppressing PET's tendency to warp. Phaetus's "Smart Fiber Reinforced Technology" forms a fiber mesh inside the material so prints stay dimensionally stable with minimal shrinkage. Prints fine on an open-frame machine — no heated chamber required.
What it prints well
- Stiff functional parts: brackets, mounts, jigs, fixtures, drone and RC frames, tooling.
- Parts that see heat or humidity — PET-CF handles both better than PLA-CF and is less moisture-fussy than nylon-CF.
- Matte black finish that hides layer lines.
Print settings (from Phaetus's TDS)
- Nozzle / print temp: 280-320°C
- Bed / build plate: 60-80°C
- Print speed: 30-90 mm/s (45 mm/s in the datasheet test)
- Cooling fan: low/off
- Enclosure: not required
- Density: 1.30 g/cm³ · Melting temp: 251°C
Hardened nozzle required (abrasive)
Carbon fiber is abrasive — it will chew through a standard brass nozzle quickly. Run a hardened steel, DLC-coated, tungsten carbide, or ruby nozzle. If you don't already have one, add a hardened nozzle to your order. A 0.4mm hardened nozzle is the baseline; 0.6mm+ feeds CF more reliably and is more wear-tolerant.
Keep it dry
PET's moisture absorption is low but it prints poorly when wet — expect stringing, popping/bubbles in the extrusion, and a rough surface. Dry before printing: oven at 100-120°C for 4-6 hours, then print straight from a dry box held below 15% RH. A filament dryer or sealed dry box is strongly recommended for any CF-filled engineering material.
Optional: annealing
Heat deflection is ~87°C as printed. Anneal finished parts at 80-100°C for 4-8 hours (Phaetus tests at 100°C/8h) to raise heat resistance toward ~175°C and increase strength. Let parts cool to room temperature naturally.
Single 1kg spool, 1.75mm, black. Sold as-is from inventory — verify your printer hotend can reach 300°C+ and has a hardened nozzle before ordering.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
