Bundle & Printcores: A Strategic and User-Centric Evolution

Unlike its predecessor, the S7, which traditionally shipped with three Printcores (two AA and one BB), the UltiMaker S8 streamlines its bundled offering to just two Printcores, echoing the S6’s approach. This seemingly minor change is, in fact, a strategic and highly logical adaptation to current professional usage trends. The S8’s default duo is exceptionally potent and versatile: one PrintCore AA+ is included for achieving fine details and handling standard, everyday prints, while a PrintCore CC+ is provided for expertly managing reinforced, abrasive, or composite materials. This configuration is carefully optimized for maximum hardware performance and industrial flexibility.

UltiMaker’s decision to pivot away from the BB Printcore in the standard bundle is informed by extensive statistical analyses of real-world usage data. Their findings indicated that complex bi-material prints utilizing soluble supports are increasingly becoming a marginal use case in typical professional environments. By adapting to this reality, UltiMaker ensures that the bundled Printcores are the most relevant and frequently used for its target audience. On the S6, UltiMaker chose to include two AA+ Printcores. With the S8, the AA+/CC+ combination strikes an ideal balance, enabling users to immediately tackle a broad spectrum of technical materials, from standard polymers to advanced composite-reinforced filaments. This approach empowers professionals to seamlessly integrate diverse materials into their workflows right out of the box. For all other aspects, the equipment supplied with the S8 remains consistent with the S7: identical wiring, accessories, automated calibration processes, and the integrated air filter.
