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.

Mosquito Heating
Element
Filament guides hold the filament as it melts in the heating block and moves toward the nozzle. Also known as heat breaks, they transition the filament from the cool area of the heat sink to the heating block.

Made of metal, heating blocks disperse heat from an insertion heater to evenly melt filament as it passes through. They also hold the temperature sensor and join the filament guide to the nozzle, making them an important connection point between parts of the heating element. Copper heating blocks conduct more heat and hold up to higher temperatures than aluminum. Use them with Mosquito heating elements.
