FFF spare part UltiMaker CC S7/S5/S3/3 print core

Composite filaments contain embedded fibrous material intended to enhance the mechanical properties of the printed object. This additive, usually in the form of glass or carbon fibres, is highly abrasive and wears down standard brass nozzles extremely quickly. Maintaining a smooth and unscathed nozzle interior, however, is essential for a clean printing process, which is why abrasive materials are always printed using harder hotends. The nozzle is produced from hardened steel with an extremely hard special ceramic coating of titanium nitride. The heater block is made of aluminium and is therefore extremely thermally conductive, reaching its target temperature faster. The heatbreak is very thick and made of titanium, meaning it insulates more effectively against heat and is more robust.
