Pros & Cons
Creality K1C
+Carbon fiber and PA support at $399 — no other enclosed CoreXY comes close at this price
+600mm/s with input shaping produces genuinely usable parts, not just benchmark numbers
+All-metal hotend is a free upgrade vs the standard K1
+Active enclosure helps with ABS/ASA warping without a separate enclosure purchase
+Creality's largest installed base means community fixes land fast
−220×220×250mm build volume is tight for large prints
−Creality OS is Klipper-based but not stock Klipper — some community configs don't transfer cleanly
−No multi-color support without third-party add-ons
−Fan noise at full speed is audible
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
