The Mosquito Liquid hotend is precisely engineered to handle high-temperature printing chambers with temperatures exceeding 80°C, allowing for the use of advanced materials and enabling a broader range of applications. Its ability to operate reliably in heated enclosures empowers users to achieve superior results in projects requiring elevated temperatures.
Corrosion-Resistant Bronze Base
Constructed from a robust and corrosion-resistant bronze alloy, the Mosquito Liquid’s heat sink, or “Base,” ensures exceptional durability and longevity. Designed for use with a wide variety of commercially available coolants, Mosquito Liquid provides users with flexibility and convenience in selecting the optimal coolant for their specific needs, whether it be water-based coolants, specialized cooling fluids, or other commercially available options.
Conduction-Cooled Bimetallic Heat Break™
Mosquito Liquid incorporates a Bimetallic Heat Break that is optimized for conductive cooling. Effectively dissipating heat from the hotend prevents heat creep and maintains consistent and reliable printing performance. 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.
Equipped for Excellence
Every Mosquito Liquid now comes with a GammaMaster Nozzle & Boron Nitride Paste, two 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. Boron Nitride Paste, a thermal conduction enhancement, and potting agent, is included to simplify heater and sensor installation.
