Ultimaker Print Core AA (0.4mm)

Ultimaker Print Cores are compatible with the Ultimaker 3, Ultimaker 3 Extended, and Ultimaker S5 3D printers. The Print Core AA aka the 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.

Important Note: Ultimaker does not support swapping the nozzles on Ultimaker print cores. If you wish to use a different nozzle size, you need to purchase a separate print core with the appropriate size nozzle. Trying to change the nozzle on a print core can result in damage to the internal components and will void the warranty.

The Next Generation of Reliability

Maximize the print performance and machine uptime with Ultimaker's swappable, material-matching print cores. Make the most out of reliable build and support material combinations for geometric freedom or print in dual color.

Ultimaker Print Cores are compatible with the Ultimaker 3, Ultimaker 3 Extended, and Ultimaker S5.

Note: If you have an older Print Core that has the silicone ring around the nozzle, this must be removed before use
