Have a Mosquito™ Hotend with the retired Heat Break/Heat Sink? Press here to upgrade your Mosquito™ Hotend to the latest version!

    We highly recommend the use of Boron Nitride paste with the Mosquito™ to provide good thermal conductivity between the hotend and heater/thermistor.

    Downloadable 3D models of the Mosquito Hotend are now available on our Documentation page.

    Seasoned hobbyists, innovators, and creators take it in stride when they’re struck with a vision of what they could build. Especially when they know that with The Mosquito Hotend™, their 3D printer can deliver the highest resolution and take on engineering-grade plastics that other desktop printers can’t come close to. With minimal layer lines and extreme precision, your vision is about to become reality. A beautiful reality.

    By engineering-grade plastics, we’re talking printing at temperatures up to 450 °C. That means you can print car parts, medical devices, and whatever else you can dream up, and you don’t have to buy an over-sized (and overpriced) printer to do the job.

    How did we accomplish this?

    By re-imagining how a hotend is designed and structured from the ground up. The materials in each part of The Mosquito Hotend™ have been hand selected to perform a specific task to optimize your printer’s performance with three goals in mind: lightning speed, beautiful resolution, and increased durability.

    The Mosquito Hotend™ is adaptable to virtually any printer, so by swapping one component, you gain the high performance benefits of a printer worth thousands more. Since The Mosquito Hotend™ (designed for beauty) and Mosquito Magnum™ (designed for speed) are the same length, any combination of these hotends can be mounted to one carriage. So you can switch between high-flow and high-precision in the same print.

    Oh yeah, and you can change the nozzle with one hand.

    Are you ready to see your vision fully realized?

    The Mosquito Hotend™ is only available for 1.75 mm filament at this time.

    Superior heat break performance
    - The heat break conducts 85% less heat into the heat sink than a typical threaded heat break
    - Steep temperature gradient at the heat break, and high tolerances along the filament path allow for better transmission of fine motor movements, resulting in beautiful, higher resolution prints
    - Steep temperature gradient at the heat break reduces the likelihood of jamming
    - Reduced heat transmission removes the need for a large heat sink
    - Composite construction of the bimetallic heat break™ allows for the use of materials optimized for heat transfer in each section of the heat break
    - Allows for hotend to be mounted with a printed, plastic adapter, without raising safety concerns

    Increased structural rigidity
    - 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, 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

    Larger temperature operating range
    - 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

    Modular/adaptable to almost any FFF/FDM printer
    - 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

    Ideal for multiple extrusion systems
    - Small form factor and light mass allows for back-to-back mounting with small nozzle-nozzle distance

    - Small mass allows for more rapid motion
    - Less reinforcement needed for the motors, belts, and drives in the motion system
