Ultimaker Print Cores are used with the Ultimaker 3, Ultimaker 3 Extended, Ultimaker S3 and Ultimaker S5 3D printers. The Print Core AA (Build Core) is used for fabrication of the actual object, whereas the Print Core BB aka the Support Core is used for creating dissolvable supports. Maximize your uptime with new, swappable Ultimaker Print Cores. Achieve extra fine detail with a swappable 0.25 mm print core AA when printing build materials including Nylon, PLA, CPE, ABS, and PP.

Important Note: Ultimaker does not support swapping the nozzles on Ultimaker print cores. The Nozzle is integrated as part of the Print Core. Trying to change the nozzle on a print core can result in damage to the internal components and will void the warranty.
