The Mosquito Conduct by Slice Engineering is a modular all-metal hotend designed with advanced adaptability, precise temperature control, and ease of use in mind. In contrast to the standard, air-cooled Mosquito hotend, it is optimized for conductive heat transfer. Its industry-leading thermal efficiency and reliable structure with patented features, such as effortless one-handed nozzle change, make the Mosquito Conduct a powerful solution against heat creep issues, such as jamming, poor heat control, etc.

A general view on the Mosquito Conduct hotend by Slice Engineering. 

Alongside enhanced 3D printing precision, various mount options, and improved noise reduction, the Mosquito Conduct hotend features advanced high-temperature capacity with heating up to 500 °C. This covers a full scope of currently available thermoplastics, including PEEK, Ultem (PEI), ASA, PC, Nylon, and more.

The device’s flexible construction allows it to fit virtually any 3D printer with an adapter required in certain cases. If you are unsure about your 3D printer model, please contact us to find the appropriate solution.

Generally, the Mosquito Conduct hotend is compatible with RepRap style nozzles (M6 x 1.0 threads with a 7 mm thread length and 12.5 mm overall length).

Construction details on the Mosquito Conduct hotend by Slice Engineering.

Both Mosquito and hotend series from Slice Engineering share the manufacturer’s proprietary Bimetallic Heat Break technology that implies efficient heat conduction and diffusion. As such, they are designed for high-performance applications due to the ability to effectively eliminate heat creep.

However, they are different in all other aspects. The Copperhead is a budget-friendly, traditional-style hotend aimed at improved quality of high-temperature 3D printing. As for the Mosquito devices, they boast innovative design with a protective roll cage around 85% thermally efficient heat break making for cold, one handed nozzle changes. Despite their differences, both options provide better printing experience, so one can choose any depending on their needs.

Optimized for conductive heat transfer

The main feature of the Mosquito Conduct hotend is its peculiar cooling system. The device is engineered to conduct heat to a small bearing bronze heat sink at the top that is called a Base. The Conduct model needs to be mounted to a metallic part or carriage that can help conduct heat away from the Base. That part must have 88 cm² of surface area exposed to room temperature air for radiative and convective heat transfer to facilitate cooling, or use liquid cooling.

Reliable against heat creep

Similar to the standard version, the Mosquito Conduct makes use of the manufacturer’s innovative technology — Bimetallic Heat Break. It involves the application of the lightweight, adaptable heat break produced from ultrathin, cold-worked stainless steel surgical tubing and sheathed in hardened copper alloy. Thus, the model conducts 85% less heat than a standard threaded heat break, which allows it to effectively prevent heat creep, reduce jamming, and improve printing resolution.

Compact and lightweight design

Due to a compact, reasonably organized structure and low mass on the carriage, the Mosquito Conduct provides more vertical build volume and maximum X-Y acceleration compared to other hotends.

Time-effective nozzle change

With its rigid construction, the Mosquito Conduct hotend ensures enhanced protection of the heat break from crashes and other abuse. The hot block remains completely stationary, which allows for a much faster and easier one-handed nozzle change. Moreover, the device incorporates quick-release geometry that makes for rapid swapping of the entire hotend in print chambers of any temperature.

Wide variety of supported materials 

The Mosquito Conduct hotend can heat up to 500 °C, which basically allows it to print with all major thermoplastics available on the market.

Universal adaptivity

One of the device’s notable features is its modularity allowing for wide compatibility. With its rigid, carefully thought-out construction, the Mosquito Conduct is suitable for the vast majority of FFF/FDM 3D printers offering smooth and quick integration.

Always ready for use

The device comes with everything one needs to start 3D printing right after receiving the package. Due to the quick installation process, the Slice Engineering Mosquito Conduct hotend provides smooth and streamlined user experience.
