The Elegoo Neptune 4 Pro and Flashforge Adventurer 5M Pro are cross-brand rivals: both are prosumer-tier printers, listed $119 apart. The Adventurer 5M Pro costs $119 more and gets you an enclosed chamber (with PA-CF on its materials list) and a top speed of 600 mm/s (vs 500); the Neptune 4 Pro answers with 26% more build volume.
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.

Cycle and deal status as of November 12, 2026. See the launch calendar →
The Neptune 4 Pro lists at $260 and the Adventurer 5M Pro at $379 — $119 apart, so the Adventurer 5M Pro costs 46% more.
Per litre of build volume, that works out to $19 for the Neptune 4 Pro versus $36 for the Adventurer 5M Pro — the Neptune 4 Pro is both cheaper and roomier, so it wins on value outright.
Our pick for most buyers is the Adventurer 5M Pro, for an enclosed chamber (with PA-CF on its materials list) and a top speed of 600 mm/s (vs 500), plus a higher editor score (7.9 vs 7.7) and better buy-now timing. Go for the Neptune 4 Pro instead if you want to spend less — it is $119 cheaper ($260 vs $379).
How we judge timing and deals: read our methodology →
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.
Removes 99% of particulates and VOCs generated during printing. One of the strongest air filtration systems in the consumer printer category.
Nozzles snap in and out without tools or heating. Swapping between 0.25, 0.4, 0.6, and 0.8mm nozzles takes seconds — ideal for classrooms and multi-user environments.
Full enclosure in a compact body that fits comfortably on a desk — unusually rare at this price point.
