For K2 Plus Ceramic Heating Block Kit features an all-metal integrated design for quick disassembly and convenient replacement. Uniform heating is achieved through excellent heat distribution and thermal insulation properties, ensuring consistent bed and nozzle temperatures. The 360° surround ceramic heater improves heating efficiency, enabling faster and more even heat transfer. The heat break is made of titanium alloy to reduce heat conduction. The nozzle is constructed from copper alloy and hardened steel, supporting printing with PLA, ABS, PETG, TPU, PP, PC, and PA filaments. The enlarged nozzle chamber enables a maximum flow rate of 32 mm³/s and supports high-speed printing up to 600 mm/s. The burr-free orifice minimizes clogging and ensures stable extrusion.
