Picking the right Anycubic Kobra 3 filament is what separates clean multi-color prints from constant ACE Pro jams and weak layer bonding.
Siraya Tech makes premium 1.75 mm filament tuned for the Kobra 3 and Kobra 3 Combo. Our PLA, PETG, TPU, and PETG-CF blends are formulated in-house and matched to the printer's 300Β°C hotend, LeviQ 3.0 auto-leveling, and ACE Pro feed system.
Print clean multi-color models, fast functional parts, and flexible components without fighting your printer at every layer.
Tuned for the Kobra 3 + ACE Pro: Every spool in this collection is engineered for the 300Β°C hotend, 300 mm/s recommended speed, and ACE Pro multi-color hub on the Kobra 3 V2 and Kobra 3 Combo.
Kobra 3 Filament That Keeps Multi-Color Prints Clean
Single-nozzle multi-color systems purge material between color swaps. Bad filament means wasted plastic and failed prints. Ours is tuned to feed cleanly through the ACE Pro hub.
Stable diameter tolerance β keeps the ACE Pro feeding consistently across 4 to 8 color swaps.
Low-moisture packaging β sealed aluminum bags stop humidity-related jams on long multi-color prints.
High volumetric flow β matched to the Kobra 3's 300 mm/s recommended speed and 20,000 mm/sΒ² acceleration.
Slicer-ready β print profiles for Anycubic Slicer Next and Bambu Studio are available on our support hub.
Pick the Right Material for Every Kobra 3 Project

PLA for Sharp, Multi-Color Prints
The Kobra 3 was designed for multi-color PLA work. Our PLA loads cleanly into the ACE Pro, swaps between spools without stringing, and produces sharp details across all four feed lines.
PETG for Functional Multi-Color Builds
PETG runs through the ACE Pro for tougher multi-color parts that need to survive outdoor use or carry load. Our PETG keeps clean layer adhesion even when the printer is pushing 300 mm/s.
Flex TPU for Single-Color Flexible Prints
TPU works on the Kobra 3 in single-color mode only, since soft filaments compress inside the ACE Pro feed path. Our Flex TPU Air 65A-82A foaming filament adjusts hardness by temperature, opening up lightweight wearables and insoles. The PEBA Air variant goes further with 50% weight reduction.
PETG-CF HF for Stiff Engineering Parts
Need rigidity? PETG-CF HF supports 150-200 mm/s printing with chopped carbon fiber reinforcement. It runs through the ACE Pro for multi-color engineering prints with low warping and a professional matte finish.
Note: Install a hardened steel nozzle on your Kobra 3 before printing PETG-CF. Brass wears out fast on carbon-fiber materials.
Why Professional Makers Choose Siraya Tech
We are not a re-spooler. We are chemists, engineers, and makers who formulate and manufacture every filament in-house.
Our spools are tested on multi-color CoreXY-class printers like the Kobra 3, so your ACE Pro stays clean, your color swaps are predictable, and your prints come out the way you sliced them.
The Kobra 3 supports PLA, PETG, and TPU. Its 300Β°C hotend and 110Β°C bed cover those materials reliably. TPU prints in single-color mode but is not compatible with the ACE Pro multi-color dryer.
Can the Kobra 3 print TPU through the ACE Pro?
No. Soft filaments compress and tangle inside the ACE Pro feed path. TPU prints on the Kobra 3, but only in single-color mode through the standard feed.
What is the max nozzle temperature on the Kobra 3?
The Kobra 3 hotend reaches 300Β°C, which handles PLA, PETG, ABS, ASA, and PETG-CF reliably. Materials that need higher temperatures, like pure PC or PA-CF, are outside its range.
How fast can the Kobra 3 print?
Anycubic recommends 300 mm/s with a maximum acceleration of 20,000 mm/sΒ². Real-world speeds depend on the filament. High-flow PETG-CF and PLA handle the upper range better than thicker materials.
Do I need an enclosure for the Kobra 3?
No. The Kobra 3 is an open-frame printer. It is not designed for engineering filaments like ABS, ASA, or nylon that benefit from a heated enclosure. Stick to materials that print well in open conditions.
