MK4S
“The tinkerer's workhorse: open, repairable and built to last.”
Will’s take Solid choice
- Compare
- MK4S vs X2D
Prusa MK4S vs Bambu Lab X2D
X2D
“Dual nozzles and a heated chamber for $649 is hard to believe.”
Will’s take Top pick
The short version
- The X2D costs $350 less.
- The X2D holds 1.5× the build volume.
- The X2D handles up to 25 colours, against 5.
- Only the X2D is enclosed, which matters for ABS, ASA and indoor use.
