  • 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 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

    • The Mosquito’s tiny form factor make 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 nozzle-nozzle distance

  • Lightweight

    • Small mass allows for more rapid motion

    • Less reinforcement needed for the motors, belts, and drives in the motion system

New Design Features

The Motor Gear is now made of Brass
The corrosion resistant material will stop the very low frequency of oxidation issues that happened to the steel gears.

The POM Gear attached to the Main Shaft is now Black
This is a pure aesthetical upgrade to mask out the dirt that shows too much on white.

The Push-Fit is now threaded
It can be removed and/or replaced to make it easier to solve clogs without ruining the BMG’s housing.



Designed To Be Flexible

The LGX™ For Flexibles Set includes a reversible heat sink that can be installed on the left or right hand side of the cold block. The heat sink also includes the hole pattern for attaching 40×40 fans.
