Feature: 1. APPLICABLE MODEL: Ceramic heating block kit is designed to work seamlessly with for Ender-3 V3 KE 3D printers, which can handle high speed printing up to 600mm/s, and the thermal fracture is composed of bimetals(brass and Ti alloy), preventing thermal creep 2. FAST HEATING: Ceramic hotend kit features a powerful 60W ceramic heating circle that increases heating efficiency and provides consistent and accelerated heat transfer. This allows it to quickly get up to a temperature of 300℃ in 40 seconds 3. HIGH TEMPERATURE RESISTANT: The thermal insulation panels in the ceramic heating block kit are all metal designed to provide higher performance while resisting high temperatures and can withstand temperatures up to 300℃ 4. HIGH HOT MELT EFFICIENCY: The high temperature resistant extruder hot end has a 30% increase in the hot melt section, and the overall design large hot melt section and superior fluidity allow to fully melt filaments even at high speed printing rates of up to 600mm/s, making it suitable for continuous high speed printing tasks 5. SUITABLE FOR FILAMENTS: This heating block kit can accommodate a variety of filaments such as Hyper PLA, ABS, PETG, TPU(95A), ASA, etc., due to its rugged design that resists high temperatures Specification: Item Type: Ceramic Heating Block Hotend Kit Heating Temperature: 300℃ Power: 60W Printing Speed: 600mm/s Flowrate: 32mm³/s.
