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 300°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 300°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 — keeps the ACE Pro feeding consistently across 4 to 8 color swaps.
Low-moisture packaging — sealed aluminum bags stop humidity-related jams on long multi-color prints.
High volumetric flow — matched to the Kobra 3's 300 mm/s recommended speed and 20,000 mm/s² acceleration.
Slicer-ready — print profiles for Anycubic Slicer Next and Bambu Studio are available on our support hub.

Pick the Right Material for Every Kobra 3 Project

The Kobra 3 hotend reaches 300°C, with an open-frame design suited for PLA, PETG, and TPU. Match your project to the right polymer below.

Material	Best For	Multi-Color (ACE Pro)	Key Strength
PLA	Detailed models, multi-color art	Yes	Sharp detail, easy printing
PETG	Functional brackets, outdoor parts	Yes	Tough, moisture resistant
Flex TPU	Phone cases, gaskets, grips	No (single-color only)	Flexible, impact absorbing
PETG-CF HF	Stiff jigs, drone parts, brackets	Yes	High-flow, low-warp, carbon-reinforced

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.

Frequently Asked Questions

What filament does the Anycubic Kobra 3 support?

The Kobra 3 supports PLA, PETG, and TPU. Its 300°C hotend and 110°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 300°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/s². 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.
