The Bambu Lab H3C (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. The H3C costs $2,239 more and gets you an enclosed chamber (with PA, PC and PA-CF on its materials list) and 156% more build volume; the Neptune 4 Pro answers with extra engineering materials (ABS and ASA).
First-generation product — recently released, still early days
Best for: Studios, engineers and power users who print many colours or materials per job, such as soluble supports, rigid-plus-TPU parts or CMYKW colour mixing, and want each material on its own dedicated tool rather than purging through a single nozzle.

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 H3C was released on Nov 3, 2026, 9 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
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 H3C is the safer buy right now — it launched only 9 days ago, 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 H3C at $2,499 — $2,239 apart, so the H3C costs 861% more.
Per litre of build volume, that works out to $73 for the H3C versus $19 for the Neptune 4 Pro — the Neptune 4 Pro is the better value per litre as well.
If you are buying before Dec 5, 2026, the active sale tips value toward the Neptune 4 Pro.
Our pick for most buyers is the H3C, for an enclosed chamber (with PA, PC and PA-CF on its materials list) and 156% more build volume, plus a higher editor score (9.0 vs 7.7) and better buy-now timing. Go for the Neptune 4 Pro instead if you want to spend less — it is $2,239 cheaper ($260 vs $2,499).
How we judge timing and deals: read our methodology →
Swaptek keeps nine tools docked, loaded and pre-heated, each with its own filament path and heater. Bambu quotes 6-second material switches and very small purge volumes per swap, so multi-material prints waste far less filament than single-nozzle AMS printing.
Each tool can carry a different nozzle size or material. That makes it possible to print a 0.2 mm detail section, a 0.4 mm structural part and a soft 75A TPU section in one job.
The AMS 3H stores and feeds filament inside a sealed unit, and a built-in dryer handles moisture-sensitive PA, PC and TPU. Older AMS units can connect for up to 24 spools.
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.
