UltiMaker offers different types of print cores, with multiple nozzle sizes. The print cores are optimized specifically for certain materials, and not all print cores are compatible with all printers or material types.

Compatibility explanation
- AA print cores: The AA print cores are compatible with all UltiMaker printers that use print cores (UltiMaker 3, S, and Factor Series). These print cores are not intended for use with abrasive materials. The high-speed printers (UltiMaker S6, S8, and Factor 4+) only have experimental profiles for the AA print cores in Cura; the AA+ cores are preferred on these models.
- BB print cores: The BB print cores are compatible with all UltiMaker printers that use print cores (UltiMaker 3, S, and Factor Series). These are specifically intended for support materials. The print core BB 0.8 is not compatible with the UltiMaker S6 and S8, and cannot be selected in Cura.
- CC print cores: The CC print cores are only compatible with UltiMaker printers with abrasion-resistant feeders (S and Factor Series), also including the Material Station. These print cores are intended for use with abrasive or composite materials. These print cores cannot be used on the UltiMaker 3 because the UltiMaker 3 feeders are not compatible with composite materials (learn more here). The high-speed printers (UltiMaker S6, S8, and Factor 4+) only have experimental profiles for the CC print cores in Cura; the CC+ cores are preferred on these models.
- DD print cores: The DD print core and Ultrafuse® Support Layer material are only available in selected regions. Printing Metal, and therefore the use of Ultrafuse® Support Layer material and the DD cores, is not recommended for use with the S series Material Station due to the curves in the internal filament path. On Factor 4, the filament path is different (smoother), so this does not affect the Ultrafuse material as much.
- HT print cores: The HT print cores are only compatible with Factor Series printers. This print core type is optimized for high-temperature materials, such as UltiMaker PPS CF. This material requires a high printing and build volume temperature to print reliably; only Factor Series printers feature a heated build chamber. For the Factor 4+, only experimental profiles are available; the CC+ core is preferred on this model.
- AA+ print cores: These print cores have a quad-chamber design that allows for 2.5× more flow; they are optimized for high-speed printing using the UltiMaker Cheetah motion planner. This print core is only compatible with printers that support Cheetah: the UltiMaker S6, S8, and Factor 4+.
- CC+ print cores: These print cores are optimized for printing abrasive composite materials at high speeds using the UltiMaker Cheetah motion planner. This print core is only compatible with printers that support Cheetah: the UltiMaker S6, S8, and Factor 4+.
Note: In UltiMaker Cura, it is still possible to select the CC+ 0.4 print core for the S6 and S8. A small number of these were originally shipped but were quickly replaced by the CC+ 0.6 print core due to reliability concerns. The CC+ 0.4 has since been discontinued. If you still have one in use, you can continue slicing for it in Cura, but please note that neither print quality nor long-term reliability can be guaranteed.
