Anycubic Kobra X

4.3

3 sources1 derived$459.99as of Aug 1

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

Ranked #5 in Best 3D Printers Under $500

Elegoo Neptune 4 Pro

4.2

3 sources1 derived$229as of Aug 1

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.

— Dual-gear direct-drive extruder with a 300°C high-temp nozzle
— Linear rods and a part-cooling fan for clean high-speed prints

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.
