Prusa CORE One+ vs. Prusa MK4S
Both printers compared directly. The better value is marked in green, where this can be determined objectively.
The key differences
- Only the Prusa CORE One+ has an enclosure. That is a clear advantage for ABS, ASA and other materials prone to warping.
- The Prusa CORE One+ is a CoreXY printer, the Prusa MK4S a bed slinger. CoreXY allows higher accelerations and is more stable with tall parts.
- The Prusa CORE One+ has the larger build volume (250 × 220 × 270 mm).
