Anycubic Kobra X vs Elegoo Neptune 4 Pro

Which is the better buy? Side-by-side on rating, price, strengths, and watch-outs — with the published ratings we averaged to get there.

The short answer

Elegoo Neptune 4 Pro comes out ahead by a narrow margin (4.4 vs 4.5). The gap is mostly about Budget buyers who want fast Klipper-based single-color printing and a high-temp nozzle for a low price. — read the strengths below before deciding.

$329.99as of Jun 7

The Anycubic Kobra X brings affordable 4-color printing to the sub-$500 market, integrating its ACE Gen 2 multicolor system directly into the toolhead for faster color swaps and less waste. Reviewers call it an excellent entry-level four-color printer with a flawless auto-leveling system. It is the budget multicolor pick, though its software trails the Bambu A1.

Strengths
  • Built-in 4-color printing (up to 19 colors) via the ACE Gen 2 system in the toolhead
  • Shorter filament path means faster color swaps and less purge waste than rivals
  • Fast multicolor speeds with a 260x260x260mm build volume
Watch-outs
  • Bed-slinger design, less rigid than enclosed CoreXY machines
  • Anycubic slicer and software are weaker than Bambu Studio
  • Multicolor still wastes some filament despite improvements

The Elegoo Neptune 4 Pro is a fast, affordable Klipper-based printer hitting 500mm/s with a dual-gear direct-drive extruder and 300°C nozzle. Tom's Hardware gave it an Editor's Choice award for its speed and quality at a low price. Its calibration process is its main weak point, but it remains a strong-value high-speed alternative to the Bambu A1.

Strengths
  • 500mm/s print speed via Klipper firmware for fast output
  • Dual-gear direct-drive extruder with a 300°C high-temp nozzle
  • Linear rods and a part-cooling fan for clean high-speed prints
Watch-outs
  • Calibration is a mixed automatic/manual process, its main weak point
  • No multicolor support
  • Smaller 225x225x265mm build volume

How they stack up

Anycubic Kobra X

The Anycubic Kobra X is the cheapest way to get built-in 4-color printing, undercutting the Bambu Lab A1 with AMS lite, but its software trails Bambu's and it is less polished overall, while it adds the multicolor that the Creality Ender 3 V3 SE, Ender 3 V3 KE and Elegoo Neptune 4 Pro all lack.

Elegoo Neptune 4 Pro

The Elegoo Neptune 4 Pro matches the 500mm/s speed of the Bambu Lab A1 and Creality Ender 3 V3 KE with open Klipper firmware, and it is faster than the Creality Ender 3 V3 SE, but its calibration is fiddlier and it lacks the multicolor of the Anycubic Kobra X.
