Mosquito Hotend (12v) - BMG-M Compatible

One of the most exciting developments in the world of 3D Printer hotends is here! The Mosquito Hotend, developed by the geniuses at Slice Engineering, is a radical new take on the hotend form.

And now with the improved keyhole design, the Mosquito Hotend is even hotter and cooler because it links up perfectly with the BMG-M from Bondtech.

The Hot Stays Hot and the Cool Stays Cool

The core to the Mosquito Hotend is in the separated module design. The frame at the cold end, which feeds the filament down, is separated entirely from the heater block by four metal support rods. This creates a spacious air gap between the two modules, where a small, copper heatsink guides the filament down into the heater block, and a small, mounted fan keeps just the right amount of air flowing through.

By combining each of these design choices, heat creep has been effectively eliminated. The heat will stay contained just where it needs to be for clean, efficient printing, in an elegant and compact form.

BMG-M Compatible

Bondtech and Slice Engineering have worked together to create a system that allows customers to upgrade their printers to have the most direct drive possible, with filament extruding through the BMG-M, directly into the Mosquito Hotend.
This takes advantage of Bondtech's Dual Drive gear design (perfect for softer filaments like Nylon and TPE/TPU), and the Mosquito's fantastic open architecture for some of the easiest, cleanest printing yet.
This is all done using the groves and keyholes that have been added to the designs--on the bottom of the BMG-M and the top of the Mosquito.

Easy Come, Easy Go

An additional, exciting benefit of the four-rod design is that the heater block is completely stationary, so inserting and removing your nozzle doesn't also move the heater block! With no need to hold the block in place, removing and installing your nozzle just became much faster and easier!

Smaller Hotend to Increase Your Build Size

All of these incredible design elements are achieved in less space than traditional hotends, so by installing a Mosquito Hotend, you actually open up more vertical build volume on your printer! The only downside to this amazing new tool is that you don't have it--yet!
