  • Set of Mosquito Hotend™ hex keys for assembly, disassembly and mounting

  • Super tasty US-made gourmet lollipop


  • The heat break conducts 85% less heat into the heat sink than a typical threaded heat break

  • Allows for hotend to be mounted with a printed, plastic adapter, without raising safety concerns

  • Composite construction of the heat break allows for the use of materials optimized for heat transfer in each section of the heat break

  • Reduced heat transmission removes the need for a large heat sink

  • Steep temperature gradient at the heat break reduces the likelihood of jamming

  • High tolerances along the filament path allow for better transmission of fine motor movements, resulting in beautiful, higher resolution prints

  • The heat break has been separated from the structural components of the hotend, allowing for a heat break that is not load bearing, and can be very thin walled. This allows for a reliable, rigid exterior structure

  • No components are prone to loosening at the mounting points

  • Nozzles can be changed with one hand (one tool), without grasping the hot block

  • In the case of a severe crash, an entirely new hotend is not necessary, parts can be easily swapped out

  • Specially-engineered high temperature copper alloy in the hot block will not soften at high temperatures in excess of 550C.

  • Threads in the hot block will not deform at high temps, allowing removal of nozzles even after multiple high temp heat cycles

  • Nickel plating on the hot block reduces radiative heat loss and prevents galling of threads

  • Compact, flat, ambidextrous form factor

  • 5 different hole mounting patterns to allow for adaptation to virtually any printer

  • Printable adapters can be created to diversify mounting options

  • The Mosquito’s tiny form factor makes it ideal for multi extrusion systems. Since the Mosquito (designed for precision) and Mosquito Magnum (designed for flow) are the same length, any combination of these hotends can be mounted to one carriage. So a typical multi-extrusion system equipped with Mosquito(s) and Mosquito Magnum(s) can switch between high-flow and high-precision extrusion in the same print. In the blink of an eye. With one-handed nozzle changes.

  • Small form factor and light mass allows for back-to-back mounting with small (14 mm) nozzle-nozzle distance

  • Small mass allows for rapid motion of the carriage
