Best Filament for the Anycubic Kobra 2 Max

Large-format single-color bed-slinger: a 420 × 420 × 500mm volume for big PLA/PETG prints on a budget.

Last updated: June 2026

The Kobra 2 Max is the previous-generation large-format option: a 420 × 420 × 500mm open-frame bed-slinger aimed at people who need size more than features. It carries the Kobra 2 family's direct-drive extruder, LeviQ 2.0 leveling, and fast cooling, but it's single-color with no ACE Pro path and a 260°C hotend.

What the Anycubic Kobra 2 Max prints well

Recommended materials for this printer:

PLA PLA+ PETG TPU

No enclosure, so ABS, ASA, PC and nylon will warp and crack. Stick to PLA, PLA+, PETG and TPU for reliable prints. Carbon- and glass-fibre composites also need a hardened nozzle first.

On a bed this large, low-warp filament is essential. PLA is the natural choice for big prints; PETG works with adhesion help. ABS and ASA will lift badly across 420mm of open, unheated bed, and the 260°C hotend rules out PC and high-temp PA. As with the rest of the line, the brass nozzle isn't ready for abrasive composites.

Suited to makers who want maximum volume cheaply for PLA/PETG: cosplay, big props, large jigs. If you need multicolor, higher temps, or enclosed high-warp materials at this size, the Kobra 3 Max (multicolor, 300°C) or an enclosed machine is the upgrade.

Filament notes for the Anycubic Kobra 2 Max

  • PLA is the safe default for large parts, with the least warp across the 420mm bed.
  • PETG works with a glue stick and careful first layer over the large area.
  • ABS/ASA warp heavily on a 420mm open unheated bed, so they aren't recommended for big parts.
  • 260°C hotend rules out PC and high-temp PA entirely.
  • Brass nozzle isn't abrasive-rated; hardened steel needed for CF/GF, and you'll be near the temp ceiling.
  • No multicolor / ACE Pro support; single color only.
  • Large single-color prints benefit from a dry spool; there's no integrated drying box.

Frequently Asked Questions

How big can the Kobra 2 Max print?
420 × 420 × 500mm, the same large-format volume as the newer Kobra 3 Max, but single-color and capped at a 260°C hotend. It's best used for big PLA and PETG prints.
Does the Kobra 2 Max do multicolor?
No. It has no ACE Pro support and prints a single color. For large-format multicolor in the Anycubic range, the Kobra 3 Max is the model that adds ACE Pro four-to-eight-color printing.
Can I print ABS on the Kobra 2 Max?
Not well at size. The open, unheated 420mm bed causes severe warping on ABS and ASA, and there's no chamber heat to hold large parts down. Stick to PLA and PETG, or move to an enclosed, actively heated machine for big high-warp parts.
What's the highest-temp filament the Kobra 2 Max can run?
The 260°C hotend tops out around ABS/ASA-class temperatures in theory, but warping makes those impractical at size. PC and high-temp PA are out of reach. The newer Kobra 3 Max raises this to 300°C.
