K2 Plus Ceramic Heating Block Kit, with 0.2/0.4/0.6mm Quick Swap Nozzle, Silicone Cover, Cleaning Pin and Wrench, for Creality K2 Plus Combo 3D Printer, 300°C High Temperature Resistant

Complete K2 Plus Hot End Kit
This fully assembled ceramic heater block kit is designed for K2 Plus Combo and K2 Plus 3D printers. It includes 0.2mm, 0.4mm, and 0.6mm hardened steel quick-change nozzles, 20 cleaning needles (0.2×8, 0.4×8, 0.6×4), 2 silicone covers, 3 bottles of silicone grease, 4 screws, and 4 wrenches—providing everything you need for efficient maintenance and printing.

Premium-Quality Materials
The nozzle is made from a combination of copper alloy and hardened steel, offering a Mohs hardness of 7.8 for exceptional durability and up to six times longer lifespan. The hot end throat uses aluminum alloy to minimize heat transfer, while the copper alloy body delivers high thermal conductivity (330 W/m·K) for consistent and even heating.

Quick-Change Nozzle System
Designed with an all-metal, one-piece structure, the nozzle and thermal break allow for fast and easy installation or replacement. The smooth inner surface ensures seamless filament flow, while the precision-machined, burr-free nozzle reduces clogging and supports stable, high-quality printing. A tight sealing connection helps prevent material leakage during operation.

Efficient Heating Performance
Equipped with a 360° ceramic heating element, this hot end provides faster heat-up times and more uniform temperature distribution. The split heat sink design minimizes heat creep, while the copper heat sink enhances cooling efficiency for better overall performance.

High-Temperature Capability
Built to handle demanding printing conditions, this heating block can withstand temperatures up to 300°C. It ensures reliable operation even during high-temperature printing tasks, making it suitable for advanced and professional use.

Wide Filament Compatibility
Engineered for versatility, this hot end kit supports a broad range of filaments, including PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, and PET-CF. It is ideal for both standard and high-performance engineering materials.

Reliable & User-Friendly Design
Whether you’re a hobbyist or a professional, this kit offers a balance of durability, efficiency, and ease of use. Its thoughtful design ensures consistent results, reduced maintenance, and a smoother overall 3D printing experience.
