Product description Key benefits Easy installation: external connection thread connector allows quick, secure mounting to compatible extruder assemblies. Wide temperature range: operates from 40 to 260 °C, providing stable performance across typical filament types and resisting both high and low temperature conditions. Precision printing: uses proven hot-end printer extruder technology to deliver high-definition print results. Ready to use: includes the hot end plus matching extruder hot end accessories to make setup and ongoing printing smoother. What it does and why you need it This extruder hotend melts and delivers filament precisely to the nozzle, enabling consistent layer extrusion and improved surface quality. The 24V, 40W heater provides reliable heat-up and temperature maintenance for steady printing performance. The external-thread connector simplifies replacement or upgrades without complex rework, reducing downtime. Important attributes Connector type: external connection thread (easy to install). Operating temperature: 40 to 260 °C. Power and voltage: 24V, 40W heater tube. Nozzle size: 0.4 mm for balanced detail and flow. Included components: heater pipe (24V 40W), block, 0.4 mm nozzle, heat sink, and air pipe connector. Compatibility: designed for use as a printer extruder hot end; fits systems that accept an external-thread hot end connector. (Confirm thread dimensions with your printer before installation.) Performance and reliability Stable operation across the stated temperature range supports a variety of filaments and reduces print failures caused by inconsistent heating. Heat sink and air pipe connector support active cooling to maintain thermal separation between the melt zone and the cold end. Typical use scenarios Detailed prototyping: produce high-definition parts and prototypes where consistent extrusion and a 0.4 mm nozzle improve surface finish. Functional parts and small-batch production: reliable temperature control and included accessories make the hot end suitable for frequent or repeated printing tasks. Printing hot rods: suited to projects described as hot rods where the specified temperature range and nozzle size meet material and detail requirements.
