This is a genuine Creality replacement hotend heating assembly, designed specifically for the SPARKX i7 3D printer. Featuring a 50W high-power heating core (2080 nickel-chromium alloy with 304 stainless steel sheath), it delivers rapid heating and supports up to 300°C for engineering-grade filaments like ABS, ASA, and PC. The tool-free quick-swap design (floating positioning with 0.05mm repeatability) allows hot-swap at 220°C without rewiring, making maintenance effortless. The integrated one-piece metal structure (high-thermal-conductivity aluminum alloy + stainless steel) ensures stable temperature and reduces leakage or clogging risks. Ideal for high-speed, multi-color printing with the CFS Lite system.  Compatibility: Creality SPARKX i7 3D Printer  Installation: Allow the hotend to cool to room temperature. Disconnect the old assembly and snap the new one into place using the quick-swap mechanism. No tools or rewiring required. Verify secure fit before printing.
