The verdict
Buy the P1S.
9/10 vs Saturn 4 Ultra's 7.8/10, and it wins 3 of 5 categories. Buy this if you print ABS, ASA, or anything that smells or warps in open air. The enclosure and filtration aren't optional extras, they're the whole point. If you only print PLA, save some money and get the A1 Combo.

What owners say
The P1S is the printer I tell people to buy when they say 'I want something that just works.'
P1S owner, r/3DprintingRefreshing a best seller. The P1S is the strong choice for anyone wanting to print ABS without headaches.
P1S owner, Tom's HardwareBatch-printing a full Warhammer army on this thing is a dream come true.
Saturn 4 Ultra owner, r/resinprintingIf you've outgrown the Mars, the Saturn is the obvious next step.

Pros & Cons
P1S
- +HEPA filter actually handles ABS fumes, not just PLA smell
- +CoreXY at 500mm/s inside an enclosed chamber
- +Reliability track record is as good as anything at this price
- −Sold without AMS, which adds another $100-150 on top
- −Enclosure lid has to come off to reach prints mid-job
Saturn 4 Ultra
- +218x123mm plate fits a full Warhammer squad in one run, not two
- +12K resolution holds up just as well as the Mars at 14K for most print sizes
- +Tilt release is worth it at this plate size: peel forces on large prints are brutal without it
- −Resin consumption goes up fast when you're filling a plate this size
- −Post-processing for a full plate run takes 45-60 minutes minimum

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.
