Pros & Cons
Elegoo Mars 4 Ultra
+9K resolution is a meaningful jump from 7K: finer surface texture, sharper edges on small parts
+Tilt release means FEP films last longer; $50 less per year in consumables is real money
+Built-in air purifier takes the edge off the smell without requiring an external solution
+WiFi monitoring means you can start a print and check it from another room
−153x77mm plate is tight for anything larger than small character models
−Still needs a wash and cure station: budget $50-80 extra
−Resin workflow is messier and slower to start than FDM
Kingroon KLP1
+Enclosed CoreXY with linear rails and Klipper at $299: this combination normally costs $400+
+Compact enough to fit on a shelf while still being fully enclosed
+Klipper access means you can tune everything from macros to pressure advance
+CoreXY inside an enclosure means ABS and PETG print cleanly
−200mm cube is the real limitation: larger parts need splitting
−Kingroon's community is thin: if something breaks, you're mostly solving it from Klipper docs and Reddit
−Needs calibration time out of the box before it prints well
