What practical reasons are there to choose the Core One over an MK4S or vice-versa? The Core One is slightly more expensive.

The Core One uses a "CoreXY" system where the extruder moves in X and Y directions instead of X and Z, and the bed moves in Z instead of Y. It eliminates issues caused by large prints progressively increasing the mass/momentum on the Y axis, but it requires a more complex system of belts. Also, the Core One only comes in an enclosure, which is good for some materials that need warmer air, but can hinder PLA, which needs cool air. Generally, it seems like if you just want to reliably print PLA, get a MK4S, but if you want the temp-controlled enclosure or filament versatility, get a Core One.

core one is enclosed and somewhat (20%?) faster

  Why does enclosed matter, though? Apparently there is a filter add-on that might help with printing something smelly? https://www.prusa3d.com/product/advanced-filtration-for-prusa-core-one/ https://www.prusa3d.com/product/advanced-filtration-for-prus...

    Many materials with desirable properties (e.g. temperature resistance, strength) can only be printed in a heated enclosure. ABS and Nylon, for example. And if you're printing ABS then you need fume extraction because unlike more common materials, ABS fumes are toxic. It's not strictly necessary for your basic PLA and PETG, but it can help sometimes if the ambient temperature is really low or if the environment is drafty which can cause prints to lift off the bed.

    > Why does enclosed matter, though? I print mostly ABS filament, and during the winter here in Washington State, I could't make my printer room hot enough to avoid warped prints from my earlier unenclosed printer. This printed completely solved that issue.

      Why use ABS instead of ASA? I personally wouldn't be comfortable printing even ASA in an unenclosed printer - ABS would be an absolute no.

> What practical reasons are there to choose the Core One over an MK4S or vice-versa? The Core One has a Core-XY motion system, meaning the print bed doesn't have to move very fast during printing. This greatly speeds up typical printing. Also there's the issue of Prusa's open-design philosophy -- you're free to modify the printer's hardware and software. I've never owned a Bambu Labs printer, so I might not be the best source for a point-by-point comparison.
