About this product

• 【Compatible Printers】This Kobra S1 extruder hot end replacement kit is designed for the Anycubic Kobra S1 and Kobra S1 Combo 3D printers. It includes 2 hot end print heads, 9 brass nozzles (0.2*3+0.4*3+0.6*3), 20 cleaning needles (0.2*8+0.4*8+0.6*4), 1 wrench, 2 silicone sleeves, and 1 tweezers.
• 【High-Temperature Resistance】The assembled hot end features an all-metal construction for excellent heat resistance, capable of withstanding temperatures up to 300°C, ensuring optimal printing results when using high-temperature filaments. It is compatible with a wide range of filaments, including PLA, ABS, PETG, TPU, PP, and PC.
• 【Anti-Clog Design】The seamless connection between the nozzle and heat block accelerates heat dissipation, while the heat block provides insulation and effectively prevents nozzle clogging. The smooth, burr-free interior of the nozzle reduces air resistance, prevents filament clogging, and ensures smooth flow.
• 【Supports High-Speed ​​Printing】The assembled hot end features an all-metal nozzle design, ensuring even heating of the print head and smooth filament flow through the nozzle, enabling high-speed printing without leaks or clogging. It supports print speeds up to 600 mm/s while still ensuring uniform extrusion.
• 【Plug and Play】The Kobra S1 pre-assembled extruder hot end kit comes pre-installed with the heater tube, thermistor, silicone sleeve, and nozzle, making installation easy. Simply replace the old hot end kit with the new one. Note: After installing this hot end print head kit, we recommend recalibrating the hot bed for optimal performance.
