【36-Piece Complete Upgrade Kit】All the accessories you need in one set. Includes 3 integrated hardened steel SPARKX i7 nozzles in 0.2/0.4/0.6mm, plus 25 cleaning needles (0.2mm x10, 0.4mm x10, 0.6mm x5), 3 SPARKX i7 silicone protective covers, 3 silicone brushes, and 2 tweezers. Perfect for precision printing, everyday projects, and high-flow production.

This is a complete nozzle replacement kit designed specifically for the SPARKX i7, meeting all your hotend maintenance needs in one stop. 【Upgraded Integrated All-Metal Design】 The SPARKX i7 hotend and nozzle are carefully crafted with an integrated all-metal structure. The integrated design minimizes filament leakage and reduces the risk of clogging, while the polished metal insulation layer provides excellent heat dissipation.

At the same time, the tightly fitted insulation cover and heating block effectively prevent filament leakage and breakage. 【Quick Replacement & High-Speed Printing】 Designed specifically for the SPARKX i7's quick-change hotend system. No complicated disassembly is required, and nozzle replacement can be completed in just a few minutes.

Printing speeds up to 500mm/s, and the optimized internal flow channel supports high-speed, high-flow printing while maintaining precise extrusion and clean, uniform layer quality. It is ideal for both fine model printing and daily batch printing, making it the ideal choice for high-speed 3D printing. 【Fast Heating & Wear-Resistant】This SPARKX i7 heating block is made of high-quality metal, heating up quickly with stable temperature.

It can withstand temperatures up to 300°C/572°F, stably supporting high-temperature printing, reducing the risk of clogging, and ensuring uniform filament output during high-flow, high-speed printing. It supports high-temperature printing with a variety of filaments, including PLA, PETG, PLA-CF, and TPU, fully meeting your printing needs. Compared to standard brass nozzles, this is a more durable upgrade option that reduces replacement frequency and lowers maintenance costs.

【Enhanced Printing Performance】 The included SPARKX i7 silicone cover improves insulation performance and temperature stability, while the SPARKX i7 cleaning needles remove impurities or clogs inside before each print, reducing printing defects. Before printing, use the silicone brush to wipe off residual debris or oozing filament to keep the nozzle clean. This practical 3D printer accessory combination helps keep your SPARKX i7 hotend performing at its best at all times.
