Key benefits - Efficient heating and stable control - 12 V 40 W heat pipe provides prompt heat-up and steady temperatures for consistent prints - Flexible installation - 1 metre lengths for both the heat pipe and the thermistor allow versatile routing and mounting in a range of printers - Accurate temperature sensing - 100k NTC B 3950 thermistor with ±1% tolerance enables precise temperature readings and better print quality - Wide filament compatibility - J head hotend supports 1.75 mm and 3.0 mm filament and is suitable for Bowden extruders, enabling use with multiple filament types Specifications - Heat pipe: 12 V 40 W, length 1 metre - Thermistor: 100k NTC B 3950 ± 1%, length 1 metre - J head hotend: compatible with 1.75 mm and 3.0 mm filament and Bowden extruders Use scenarios - Scenario 1: Upgrading a Bowden-fed 3D printer to handle both 1.75 mm and 3.0 mm filament, enabling flexible filament choices without hardware changes - Scenario 2: Printing with different materials such as PLA, PETG, and ABS that require different temperatures, benefiting from fast heat response and precise temperature control for consistent results - Scenario 3: Installing in space-constrained builds or test benches where 1 metre leads for the heat pipe and thermistor simplify routing to the control board
