The Anycubic Kobra 3 Max (professional) and Qidi Tech Plus4 (prosumer) come from different brands and sit in different tiers, so this is less a head-to-head than a question of how much printer you need. Note that the Plus4 has been replaced by the Plus5 and is no longer sold new. The Plus4 costs $100 more and gets you an enclosed chamber (with ASA, PA, PA-CF, PC and PPS-CF on its materials list); the Kobra 3 Max answers with 239% more build volume.
Just released — full support runway ahead
Best for: Makers who need a very large print area for props, architectural models, or batch production — and want multicolor without paying professional-tier prices.
Full details →This printer is no longer sold new. It has been replaced by the Qidi Tech Plus5.
Best for: Makers and small businesses who need a large enclosed build volume for engineering materials at a prosumer price — particularly those printing PA-CF, ABS, and PC at scale. Look for clearance deals — the Plus5 is the current model.

The Kobra 3 Max was released on Oct 1, 2026, 42 days ago. Its previous release cycle ran about 716 days, so it is 6% of the way through — roughly 674 days before a successor would be due at that pace.
The Plus4 has been replaced by the Plus5 and is no longer sold new, so there is no release cycle left to time — any unit you find now is leftover or second-hand stock.
On timing alone, the Kobra 3 Max is the safer buy right now — it is only 6% of the way through its expected cycle, while the Plus4 has already been replaced by the Plus5.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Kobra 3 Max lists at $599 and the Plus4 at $699 — $100 apart, so the Plus4 costs 17% more.
Per litre of build volume, that works out to $7 for the Kobra 3 Max versus $27 for the Plus4 — the Kobra 3 Max is both cheaper and roomier, so it wins on value outright.
Buy the Kobra 3 Max. The Plus4 has already been replaced by the Plus5 and is no longer sold new, so it is only worth considering at a clearance price. If the Plus4 appealed to you, the fair comparison today is the Kobra 3 Max against the Plus5.

How we judge timing and deals: read our methodology →
One of the largest build volumes available at a consumer price — ideal for life-size props, large terrain tiles, and batch production.
Few printers offer multicolor at this scale. The ACE 2 Pro enables filament switching across the full 420×420 bed area.
Delivers large-format multicolor at a fraction of professional large-format printer costs.
One of the largest build volumes in the prosumer enclosed category — 40% more printable area than the Bambu X1C at a lower price point.
The second-generation active heating delivers consistent chamber temperatures for PA, PA-CF, ABS, ASA, and PC with minimal warping across the full build plate.
Handles high-performance engineering composites including PA-CF, PET-CF, and PPS-CF without requiring a separate hotend upgrade.
