The Anycubic Kobra 3 Max (professional) and Elegoo Neptune 4 Pro (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. Both are open-frame bed-slinger printers with automatic calibration. The Kobra 3 Max costs $339 more and gets you 557% more build volume and 4-slot multicolor; the Neptune 4 Pro answers with extra engineering materials (ASA).
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 →Overdue for a refresh — no successor announced yet. Prices should be at their lowest
Best for: Budget-conscious makers who want a capable bed-slinger with Klipper firmware for customization — without Bambu's closed ecosystem or Prusa's premium pricing.

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 Neptune 4 Pro was released on Jul 15, 2023, 1,216 days ago. Its previous release cycle ran about 450 days; it is now 766 days past that point and no successor has been announced.
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 Neptune 4 Pro is 766 days past its ~450-day cycle with no successor announced.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Neptune 4 Pro lists at $260 and the Kobra 3 Max at $599 — $339 apart, so the Kobra 3 Max costs 130% more.
Per litre of build volume, that works out to $7 for the Kobra 3 Max versus $19 for the Neptune 4 Pro — so the pricier Kobra 3 Max actually gives you more build space per dollar.
Our pick for most buyers is the Kobra 3 Max, for 557% more build volume and 4-slot multicolor, plus a higher editor score (8.0 vs 7.7) and better buy-now timing. Go for the Neptune 4 Pro instead if you want to spend less — it is $339 cheaper ($260 vs $599).
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.
The Neptune 4 Pro ships with Klipper pre-installed — enabling advanced input shaping, pressure advance, and configuration flexibility without modding.
A 500 mm/s rated speed at a price significantly below Bambu and Prusa alternatives.
Full automatic bed leveling reduces setup time and calibration friction.
