Anycubic Kobra 3 Max Combo 3D Printer, 600mm/s, 420x420x500mm, Multi-Color Review (2026)

Who should consider this printer

The Kobra 3 Max Combo targets makers building large single pieces such as cosplay armor panels, propmaking projects, or big display models where a standard 220mm bed forces splitting a design into parts. Anycubic's own product and wiki pages describe a 420 x 420 x 500mm build volume paired with multi-color printing through the ACE Pro filament system, which lets a single large print carry logos, panel lines, or color blocking without a separate painting pass. That combination suits hobbyists and small studios producing large props or signage more than anyone printing small functional parts, where the extra bed size and color hardware add cost and complexity without much benefit.

Build volume and print speed

Anycubic's store page and the Amazon listing both confirm a 420 x 420 x 500mm build volume, among the larger consumer FDM volumes available, and a rated top speed of 600mm/s. Anycubic's specifications also list 10000mm/s squared acceleration and automatic bed leveling with vibration compensation intended to keep quality consistent even as the machine moves quickly across such a large bed. The printer uses 1.75mm filament only and is rated for PLA, PETG, ABS and TPU according to Anycubic's wiki. A large flat PEI-style plate is included, and the hotbed is described as heating in about 125 seconds despite its size.

Multi-color system and combo contents

The Combo package bundles the printer with Anycubic's ACE Pro filament system, which the company's store page describes as supporting 4-color printing per unit, or up to 8 colors when two ACE Pro units are paired together. The ACE Pro also handles filament drying and automatic refill so a print can continue onto a fresh spool of the same material without stopping. Anycubic markets this as the largest consumer-grade multicolor printer available. The tradeoff of any multi-material system on a print this large is purge waste, since every color change on a big model can use meaningfully more filament than the part itself, especially on designs with many small color regions.

How it compares with similar large-format printers

Against the ELEGOO Neptune 4 Max, which shares a similar 420 x 420mm footprint and a comparable 500mm/s rating, the Kobra 3 Max Combo adds native multi-color printing that the Neptune 4 Max does not offer, at the cost of extra hardware bulk around the printer. Compared with Anycubic's own non-combo Kobra 3 Max models, the Combo's main addition is the ACE Pro system itself; buyers who only need single-color large prints can save money and desk space with the standalone Kobra 3 Max instead. Against older large-format machines like the original Kobra Max, the newer Kobra 3 line adds meaningfully higher rated speed and auto leveling.

Bottom line

The Kobra 3 Max Combo earns its place for builders who genuinely need both a large bed and multi-color output in one machine, such as cosplayers finishing armor pieces or makers producing branded display props at scale. The 420 x 420 x 500mm volume and 600mm/s speed rating make big single prints realistic instead of multi-day jobs, and the ACE Pro system removes a lot of manual filament swapping. Anyone who only prints single-color parts, or who lacks the desk space for the printer plus one or two ACE Pro units alongside it, will get better value from a simpler large-format machine.
