The Ultimaker BB Print Core is designed to be used with Ultimaker 3D Printers. It features a small nozzle measuring just 0.40 millimeters to support finer 3D printing tasks. This print core is also known as the Support Core. It is exclusively used to support water-soluble materials like polyvinyl alcohol (PVA) filaments. It delivers superior geometric freedom in dual extrusion prints.
