Prusa
MK4S
About This Printer
Premium · $700–$900The MK4S is an evolutionary update to the MK4, adding input shaping via an accelerometer for noticeably faster print speeds without the ringing artifacts that plague cheaper printers at high speed. Existing MK4 owners can upgrade via a kit. It's the fastest Prusa i3-style printer ever, while retaining all the open-source goodness and reliability the brand is known for.
What it does well
- Input shaping allows significantly faster printing with less ghosting
- All MK4 strengths — loadcell leveling, open-source, Nextruder
- MK4 owners can upgrade for a fraction of the full price
- Best print quality in the Prusa i3 lineup
- Excellent long-term reliability record
Limitations to know
- Still an open-frame design — no built-in enclosure
- Slower than enclosed CoreXY machines at this price
- Premium pricing for an i3-style machine
