How It Scores
Pros
- +320×320×385mm at $299 — the largest build volume at this price point
- +Stock Klipper means real input shaping, pressure advance, and Moonraker API access
- +Direct-drive handles TPU and flexible filaments without clog risk
- +Mainsail interface enables remote monitoring and print farm integration
- +Dual Z-axis prevents gantry sag on tall prints
Cons
- −Open-frame limits material compatibility — ABS/ASA require an enclosure
- −500mm/s achievable but optimal quality typically at 200-300mm/s
- −Large bed means longer homing and leveling cycles
- −Elegoo's support and community is smaller than Creality's
What Owners Say
“The Neptune 4 Plus offers an impressive build volume and genuine Klipper firmware at a price that makes larger, pricier printers hard to justify.”
— 3DPrintBeginner
“Elegoo's Neptune 4 Plus is a serious large-format contender — stock Klipper and a huge bed at $299 is hard to argue with.”

Verdict
The Neptune 4 Plus competes directly with the Ender 3 V3 Plus for the large-budget title. It wins on raw build volume (385mm height vs 330mm) and ships with stock Klipper instead of Creality's fork. The Ender 3 V3 Plus has a larger community and is marginally faster at 600mm/s. Choose Neptune 4 Plus if height matters or you want clean stock Klipper; choose Ender 3 V3 Plus if community resources are a priority.
