Mosquito Hotend 1.75mm – Slice Engineering

Mosquito Hotend 1.75mm – Slice Engineering


In Stock!

The Mosquito Hotend is a deviation from the long established and copied RepRap hotend and heatsink. It is so efficient that printing with temps up to 400C is possible on a standard setup if your thermistor and heater allow it.

The Mosquito hotend is what started the Slice Engineering journey.  Designed to have a small form factor, low mass, short retraction, and optimized heat transfer, the Mosquito uses the highest grade materials available, all engineered and built for performance in the USA.

Mosquito is built to accommodate standard 6 mm heater cartridges, 3 mm thermistors, and RepRap style nozzles (as made by E3D, Microswiss, Olssen Ruby, etc.). We also highly recommend the use of Capricorn XS tubing during installation to achieve the best printing results. If you can source some super fast 50W heaters then these puppies will FLY!

There is a reasonable selection of adapters to allow you to mount the Mosquitoes on the Bondtech kits as direct drive or bowden.
