Description The cartridge heater slots into the hot end of a 3d printer & heats it, to melt the plastic that flows in. Over time, the heater needs to be replaced. In order to handle the high temperatures, the contacts of these heaters are arc welded (not soldered). So buying a new heater is the best option as it comes with pre-connected wires which you just plug into your head PCB easily. A new heater offers consistent heating, which makes your extrusion smooth, & thus your printer prints clean lines. This improves part strength & interlayer adhesion.
