3D Printer Extruder Heating Elements
Replace damaged heating elements in your 3D printer, or switch them out to print at a faster speed or higher temperature. Also known as hotends, these heating elements receive filament from an extruder, melt it, and then pass it through a nozzle onto the part being printed. They are compatible with most fused filament fabrication (FFF) 3D printers. Changes to the heating element or temperature cartridge will also require a software update, or your printer may overheat.
Select a heating element with a voltage and extrusion type that match your printer. In printers with a direct feed, the extruder is attached to the heating element, feeding filament directly into it.
For printing high-temperature filaments, such as PEEK and Ultem PEI, use Mosquito heating elements. They reach temperatures up to 149° C or 300° F higher than V6 or Volcano styles, so you can melt a wider variety of materials. These heating elements come with everything you need, and are partially assembled—you’ll need to connect the insertion heater and temperature sensor.

Before installing printer components onto the heating block, coat the mounting holes with non-bonding heat transfer compounds. Also known as thermal paste, these compounds transfer heat to temperature sensors, which improves accuracy. They also keep components from sticking to the heating block, making them easier to remove.

Temperature sensors measure the temperature of the heating block, convert it into an electrical signal, and send it to the printer controller. This tells the printer when the heating element is warmed up and ready to print, and helps maintain a consistent temperature throughout the printing process. When choosing your sensor, make sure the maximum temperature of your heating element does not exceed the maximum temperature of the sensor.
