Mosquito Hotend Printing

Rigid “Roll Cage” Structure

Machined out of aircraft-grade aluminum, the Mosquito Hotend’s heat sink is built like no other on the market. Designed with our patented “roll cage” design, the heat sink connects to the hot block with a rigid tubular structure. This unique feature protects the delicate heat break from crashes and other abuse and allows one-handed nozzle changes.

Bimetallic Heat Break

Bimetallic Heat Break™

Mosquito’s Bimetallic Heat Break is designed to eliminate heat creep and jamming, improve print resolution and allow for shorter retractions. Crafted with a highly conductive copper alloy and strain-hardened, abrasion-resistant steel, this heat break conducts 85% less heat up the filament path when compared to standard threaded heat breaks.

Mosquito Hot Block

Super-Conductive Hot Block

Mosquito’s hardened copper alloy hot block is nickel plated and rated to 500°C, enabling printing of every commercially available filament, from basic PLAs to custom, medical-grade PAEKs. The hot block design isolates the sensor from the heater with a physical air gap, improving the temperature feedback loop.

Mosquito Silicone Boot with Nozzle

Equipped for Excellence

Every Mosquito Hotend comes with three essential accessories that elevate your 3D printing experience. The GammaMaster® Nozzle excels in even the most demanding applications with robust, abrasion-resistant performance and exceptional thermal capabilities. Safeguard your hot block with the Mosquito Silicone Boot, providing essential protection from cold air and filament for optimal performance. Additionally, Boron Nitride Paste, a thermal conduction enhancement, and potting agent, is included to simplify heater and sensor installation.
