The Creality Ender 3 V3 KE (entry) and Prusa Research MK4S (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 Note that the Ender 3 V3 KE has been replaced by the Ender 3 V4 and is no longer sold new.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 MK4S costs $450 more and gets you extra engineering materials (ABS, ASA, PA and PC) and an open-source design.
This printer is no longer sold new. It has been replaced by the Creality Ender 3 V4.
Best for: Budget-conscious beginners who want fast Klipper-based printing without the Bambu ecosystem or Prusa premium — and are comfortable with a more hands-on setup experience.

Cycle and deal status as of November 12, 2026. See the launch calendar →
The Ender 3 V3 KE lists at $279 and the MK4S at $729 — $450 apart, so the MK4S costs 161% more.
Per litre of build volume, that works out to $24 for the Ender 3 V3 KE versus $63 for the MK4S — the Ender 3 V3 KE is the better value per litre as well.
Buy the MK4S. The Ender 3 V3 KE has already been replaced by the Ender 3 V4 and is no longer sold new, so it is only worth considering at a clearance price. If the Ender 3 V3 KE appealed to you, the fair comparison today is the MK4S against the Ender 3 V4.

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.
MK4 and MK3.5 owners can upgrade to MK4S specs without purchasing a whole new printer. This is Prusa's commitment to owners and is unique in the industry at this level.
Firmware, PCB schematics, hardware designs, and slicing profiles are all published under open licenses. You own the printer completely.
Prusa's forum, knowledge base, and repair guides are unmatched. Parts are stocked and available for years after purchase.
