What owners say
My MK3 ran for 5 years without a single failed print. The MK4S continues that legacy.
Prusa MK4S owner, r/prusa3dIf reliability is your #1 priority, nothing beats Prusa. Nothing.
Prusa MK4S owner, Thomas Sanladerer (YouTube)True tool-changing is a different league from filament swapping. The XL actually delivers.
Prusa XL owner, r/prusa3dThe most capable consumer printer ever made. If you need it, you know you need it.

Pros & Cons
Prusa MK4S
- +Prusa's QC is genuinely better than anyone else's: every printer is test-printed before shipping
- +PrusaSlicer is open source and powerful, no subscription, no cloud required
- +Customer support answers in hours, not weeks
- −200mm/s max is a third of what CoreXY machines do at half the price
- −$929 for an open-frame bed-slinger is a hard sell in 2025
Prusa XL
- +5 independent tool heads means true material switching, not color blending on a single hotend
- +360mm cube handles parts that can't be split and glued
- +Segmented heated bed powers down unused zones, saving real electricity on large prints
- −$1,999 and you still print at 200mm/s: the speed is hard to accept at this price
- −Delivery times have been 2-4 months; plan accordingly
Buy these with it
A printer does nothing without these. Grab them in the same order.
- ELEGOO PLA filament, 1kgThe easy filament to start on. Prints at low temperatures and warps less.
- ELEGOO PETG filament, 1kgTougher and more heat tolerant than PLA, for parts that get handled or sit in the sun.
- SUNLU filament dryer S1 PlusWet filament causes stringing and rough surfaces. A dryer fixes that before you blame the printer.
