UltiMaker Print Core BB

Ultimaker Print Core BB: the key to complex geometries

The Ultimaker Print Core BB is a specialised hot end designed specifically for water-soluble support materials such as PVA and breakaway support material. By using a material-specific internal geometry, the BB core ensures reliable extrusion and prevents the common clogging issues often associated with support filaments. When paired with an AA core for your build material, the BB core unlocks total geometric freedom, allowing you to print intricate internal cavities and complex overhangs with ease.

The Print Core BB is available in 0.4 mm and 0.8 mm nozzle diameters, allowing you to choose between standard precision and high-speed support generation.

Key benefits:

• Support material-optimised: Specifically engineered to handle the unique properties of PVA, ensuring consistent flow and high-quality support structures.
• Quick-swap design: Effortlessly switch between print cores in seconds without the need for tools, maximising machine uptime and productivity.
• Accurate thermal monitoring: Integrated electronics provide precise, real-time temperature data, maintaining the optimal thermal profile to prevent support material degradation.
• Enhanced reliability: Equipped with a protective silicone nozzle cover that prevents filament leaks and protects the heater block from debris.
• Unmatched versatility: Enables the creation of functional mechanical assemblies and highly detailed prototypes that would be impossible to print without soluble supports.

Applications:

Perfect for concept models with moving parts, sacrificial moulds, and complex engineering prototypes. Typically used in Slot 2 of your Ultimaker printer in tandem with an AA core in Slot 1.

Technical tip:

Use the 0.4mm BB for standard support tasks and fine surface finishes. Switch to the 0.8mm BB when printing large models to significantly reduce print time by generating thicker support layers.

Note: This print core is compatible with the Ultimaker S-series (S8, S7, S5, S6, S3) and the Ultimaker 3 family.
