The Jhead hotends are the original, made in USA by the inventor. This kit contains (1) Hot end with a 0.35 mm nozzle to use with 1.75 filament (PLA or ABS) (2) Resistor (3) Thermistor (4) PTFE Teflon Tubing for the resistor and thermistor.
Original, made by the inventor, not made in China
Lightweight. Prints fast. Heats up fast. Accurate temperature reporting. Prints reliably with both ABS and PLA. (PLA may require a small fan to provide air-flow through the cooling vents which are milled in the sides of the nozzle holder.)
Easily interfaces with the most popular RepRap extruders, such as Wade's Extuder and Greg Frost's Hinged Accessible Extruder.
Simple design. Number of custom machined parts is kept to a minimum.
Resistor is used as a heater. No need to wrap nichrome wire or to bake a heater core. Heat transmission is improved because there is no thermal junction where a separate heater would screw onto the nozzle.
