The BMG meet's the Mosquito hotend in spectacular fashion

Bondtech has created an incredible hotend in the BMG, lightweight but also strong and featuring dual drive gears. The Mosquito Hotend from Slice Engineering is the best of light weight, minimalist hotends and now - they live as one. The new Mosquito hotend features mounting holes and locating indents that make if mount perfectly to the bottom of the BMG-M extruder for a lightweight, dual-drive, geared direct-drive system.

Dual-Drive

Two drive wheels grip the filament from both sides, providing a strong and reliable feed into the hotend. From common materials like PLA and ABS to flexibles like PRO Series Flex or Ninjaflex, the dual-drive gears of the Bondtech BMG will deliver a consistent flow of filament in either direct drive or bowden configurations.

Easily adjustable tension

The BMG is designed with a door on the side which holds one of the dual-drive gears. This door is held closed with a spring-tensioned thumbscrew. This thumbscrew enables precision tensioning of the drive gears for the perfect hold on filament, as well as the ability to release the tension and easily load or unload filament. All you need to do is press away from the extruder and the spring will compress just enough to release the material, letting you freely feed it directly into the hotend.
