The Elegoo Neptune 4 Pro and Qidi Tech Q2 are both prosumer-tier printers, but the Q2 costs 1.9× as much — so the question is what the extra money buys. The Q2 costs $239 more and gets you an enclosed chamber (with PA, PA-CF and PC on its materials list) and 4-slot multicolor.
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 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 Q2 was released on Aug 20, 2025, 449 days ago. Its previous release cycle ran about 518 days, so it is 87% of the way through — roughly 69 days before a successor would be due at that pace.
Both are overdue for a refresh with no successor announced. That should keep prices near their lowest, but a replacement could be announced at any time — check the launch calendar before buying. The Neptune 4 Pro is the more overdue of the two.
Cycle and deal status as of November 12, 2026. See the launch calendar →
The Neptune 4 Pro lists at $260 and the Q2 at $499 — $239 apart, so the Q2 costs 92% more.
Per litre of build volume, that works out to $19 for the Neptune 4 Pro versus $27 for the Q2 — the Neptune 4 Pro is the better value per litre as well.
Our pick for most buyers is the Q2, for an enclosed chamber (with PA, PA-CF and PC on its materials list) and 4-slot multicolor, plus a higher editor score (8.2 vs 7.7). Go for the Neptune 4 Pro instead if you want to spend less — it is $239 cheaper ($260 vs $499). One caveat: the Q2 is late in its cycle (87% through), so check the launch calendar before you buy.
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.
The Q2 actively heats the print chamber — not just passively traps heat. This is the key differentiator for reliable ABS, ASA, PA-CF, and PC printing without warping.
Triple-stage filtration removes 99.5% of particulates and VOCs — essential for printing ABS and ASA in a home or office environment.
Handles the full spectrum of engineering filaments including carbon and glass fiber composites without a hotend upgrade.
