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 5 Ultra
+14K resolution renders chainmail and sword hilts at a level FDM can't get near
+Tilt release means fewer ripped FEP films mid-print
+Built-in air purifier cuts the resin smell noticeably; still needs ventilation but less aggressively
+WiFi monitoring so you don't have to babysit the machine
−Build plate is 153x89mm: anything larger needs to be sliced and assembled
−Resin printing means gloves, IPA, and a wash station are non-negotiable purchases
−Post-processing adds 30-45 minutes after every print: wash, cure, support removal
