Anycubic Kobra 3 Max

Eighty-eight litres with a four-colour changer attached is a combination nothing else here offers: the other large-format machines are single-colour, and the other multi-colour machines are a quarter of this size. A 500 mm Z is the tallest in this catalogue, which is the number that matters for helmets, vases and full-height props. The physics caveats are severe — a 420 mm bed travelling in Y at a claimed 20,000 mm/s² is an enormous mass to reverse, so real print speeds on anything tall are a small fraction of the headline, and a multi-colour print at this scale generates a purge block that is itself a substantial object. No enclosure means PLA and PETG. Treat the speed and colour claims as things the machine can do rather than things it does well simultaneously, and it is very good value for large single-colour work.

Real speed ceiling

Not published

Anycubic does not publish a volumetric flow rate for the Kobra 3 Max, so its 600 mm/s claim cannot be checked against what the hotend can actually melt. We do not estimate one.

Features

420 × 420 × 500 mm — 88.2 litres, and the tallest Z here
ACE Pro four-spool changer with drying
Klipper with input shaping and strain-gauge levelling
Camera with AI failure detection

What it does well

The only machine here that pairs a very large volume with a four-colour changer
500 mm of Z height, matched only by the SV08 Max at twice the price
88 litres for $493 is outstanding value on volume alone
Camera and AI monitoring matter more here than anywhere, given multi-day print times

Where it gives ground

A 420 mm bed reversing in Y makes the 600 mm/s claim meaningless on tall parts
Multi-colour at this scale produces a purge block that is a large object in its own right
No enclosure, so 88 litres of anything but PLA and PETG will warp
Not hardened, no published flow rate, and partial assembly on a very large frame
