Our take on the Original Prusa MK4S 3D Printer

The Original Prusa MK4S is an open-frame FDM printer with a 250 x 210 x 220 mm build volume and the Nextruder toolhead, which uses a load cell for Z-homing instead of a probe. It prints at layer heights from 0.05 to 0.30 mm and Prusa rates it about twice as fast as earlier models. The best new price is $699.00 at Printed Solid as of November 5, 2026, and 4 stores list it new.

Pros
  • Load cell Z-homing removes manual first-layer tuning
  • Nextruder toolhead with quick-swap nozzles
  • Prusa Connect, LAN and NFC for remote monitoring
  • Power panic hardware resumes prints after power loss
  • Large community and long-running firmware support
Cons
  • Open frame, so no enclosure for ABS or ASA out of the box
  • Kit build takes hours and needs careful assembly
  • Single extruder, no multi-color without add-ons
  • 230 V input limits use on 120 V US outlets without a step-up
  • 7 kg frame is light but not portable-friendly

Questions and answers

Is the MK4S worth it over the MK4?
The MK4S adds the Nextruder improvements and faster printing over the MK4. If you already own an MK4, the upgrade kit is cheaper than a new printer. New buyers get the faster machine at the same $699.00 best price at Printed Solid as of November 5, 2026.
Kit or assembled?
The kit is cheaper and teaches you the machine, but takes hours to build. The assembled version costs more and arrives ready to print. Both have the same 250 x 210 x 220 mm build volume.
Does it work on US 120 V power?
The listed input voltage is 230 V, so check the version you order before plugging it into a US outlet. A 120 V variant or a step-up transformer may be needed.
What filaments can it print?
PLA and PETG print well on the open frame. ABS and ASA need an enclosure for best results, and the printer draws about 80 W on PLA settings.
What's in the box?
The printer ships with the optional ESP Wi-Fi module, and the kit includes parts for assembly. A USB drive is the storage type, and there is no filament spool included.
When is it cheapest?
The best new price seen is $699.00 at Printed Solid as of November 5, 2026. Prusa runs sales around holidays, so watch for kit discounts then.
