The Creality Ender 3 V3 KE (entry) 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. Note that the Ender 3 V3 KE has been replaced by the Ender 3 V4 and is no longer sold new. Both are open-frame bed-slinger printers with a 500 mm/s rated top speed and automatic calibration. The Ender 3 V3 KE costs $19 more, without a hardware advantage on the specs we track; the Neptune 4 Pro answers with extra engineering materials (ABS and ASA) and 15% more build volume.

How we judge timing and deals: read our methodology →
The KE keeps the Ender 3's familiar bed-slinger layout but runs Klipper-based firmware, reaching 500 mm/s without the Bambu premium.
The Ender 3 series has one of the largest 3D printer communities in the world, with thousands of documented modifications and upgrades.
If you outgrow the KE, the Creality K2 and K2 Plus are natural next steps within the same brand ecosystem.
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.
