The Elegoo Neptune 4 Pro (prosumer) and Qidi Tech Q2C (entry) 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 Q2C costs $139 more and gets you an enclosed chamber and 4-slot multicolor; the Neptune 4 Pro answers with extra engineering materials (ABS).
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.
Full details →First-generation product — recently released, still early days
Best for: Budget makers who primarily print PLA, PETG, and TPU and want a large enclosed CoreXY at $379. Not the right choice if you regularly print ABS, ASA, PA, or PC.

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.
The Q2C was released on Jan 14, 2026, 302 days ago. It is a first-generation product, so there is no earlier cycle to predict its successor from.
On timing alone, the Q2C is the safer buy right now — it launched only 302 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 Q2C at $399 — $139 apart, so the Q2C costs 53% more.
Per litre of build volume, that works out to $19 for the Neptune 4 Pro versus $21 for the Q2C — the Neptune 4 Pro is the better value per litre as well.
Our pick for most buyers is the Q2C, for an enclosed chamber and 4-slot multicolor, plus a higher editor score (8.1 vs 7.7) and better buy-now timing. Go for the Neptune 4 Pro instead if you want to spend less — it is $139 cheaper ($260 vs $399).
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.
270×270×256 mm is larger than the Bambu P2S and X2D at a lower price. The passive enclosure keeps PLA and PETG prints consistent without needing active heating.
The Q2C works with the Qidi Box multi-filament system — up to 4 units can be chained for 16-color printing, sold separately at $228 per unit.
Same rated top speed as Bambu Lab printers, placing it in the fastest tier of consumer FDM printers.
