The Anycubic Kobra S1 Ace 2 Pro Combo is a fully enclosed CoreXY FDM 3D printer bundled with the ACE 2 Pro multi-material unit. It prints in 4 colors as standard, expandable to 16. The build volume is 250 mm × 250 mm × 250 mm, and leveling is fully automatic with no manual Z-axis compensation.
The printer uses light-rail X and Y axes and a dual-gear short-range extruder. It reaches speeds up to 600 mm/s at 20000 mm/s² acceleration, with layer thickness from 0.08 mm to 0.28 mm. The standard 0.4 mm brass nozzle is quick-detachable. The hotend heats to 320°C and the heated bed to 120°C.
The ACE 2 Pro unit dries filament during printing at up to 65°C. It has a built-in temperature and humidity sensor and a solenoid valve that expels moist air. The enclosed chamber has an activated carbon air filter. A chamber camera supports AI spaghetti detection and time-lapse photography. The printer also offers filament runout detection with auto-resume and power-loss recovery.
