Features: Engineered with steel and hardened alloy nozzles, the hotend kit ensures exceptional durability and heat resistance for high intensity 3D printing projects. Equipped with optimized heating block and thermistor module, this assembly achieves rapid temperature control (0-320°C) while minimizing filaments clogs during continuous operation. Ideal for engineers, product designers, and prototyping enthusiasts requiring precise extrusion for functional prototypes or industrial components. Perfect for extended printing of architectural models, mechanical parts, and temperature sensitive filaments like ABS/TPU in workshop environment. The easy installation system allows seamlessly compatibility for KobraS1 printers, delivering enhances layer adhesion and surfaces finish for professional 3D outputs. Specifications: Component: Silicone+Steel Nozzle: 0.4mm/0.6mm (optional) Applicable printer model: for KobraS1 3D printer Package Includes: 1set Ceramic Hotend with Nozzle note: Please allow 1-10mm errors due to manual measurement.
