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 Hot End Kit:
This assembled ceramic heater block kit includes everything you need for efficient 3D printing: 0.2mm, 0.4mm, and 0.6mm hardened steel quick-change nozzles, 20 cleaning pins (0.2×8, 0.4×8, 0.6×4), 2 silicone sleeves, 3 bottles of silicone grease, 4 screws, and 4 wrenches. Fully compatible with K2 Plus Combo and K2 Plus 3D printers.

Premium Material Construction:
The nozzles are made from copper alloy and hardened steel, offering a Mohs hardness of 7.8 for enhanced durability—up to 6 times longer lifespan. The hot end throat uses aluminum alloy to reduce heat transfer, while copper’s high thermal conductivity (330 W/m·K) ensures even heating.

Quick-Change Nozzle Design:
Features an all-metal, one-piece structure for easy installation and removal. The smooth inner surface allows consistent filament feeding, while burr-free nozzles ensure stable printing and minimize clogging. Tight connections help prevent leakage during operation.

High Thermal Efficiency:
Equipped with a 360° ceramic heater for faster, more uniform heat distribution. The split heat sink design reduces heat creep, and the copper heat sink improves cooling performance for consistent print quality.

Wide Filament Compatibility:
Supports a broad range of filaments including PLA, ABS, PETG, TPU, PP, PC, PLA-CF, PA-CF, and PET-CF. Withstanding temperatures up to 300°C, it is ideal for both standard and high-performance engineering materials.
