Do I need a cooling fan with the Mosquito?
The Mosquito™ hotend can function without active cooling (a fan) under certain conditions, but it is advisable to use a fan when printing with PLA and other lower temperature plastics (PETG, ABS, etc). The cooling fan can be positioned on either side of the heat sink, but it must face the heat break. Meaning, airflow should be directed (“pushed”) toward the heat break, NOT pulled through it.
Now, about those certain "conditions". The Mosquito™ is extremely thermally efficient and does not require as much cooling as common hotends. The primary heat sink in the FFF process is actually the filament itself - it absorbs lots of heat as it moves into the melt zone and is extruded. Higher temperature filaments absorb more heat than lower temperature filaments like PLA or PETG. Combining this property of the filament with the Mosquito™ thermal efficiency and print jobs with low, infrequent retractions, and high flow rates equate to very little heat creep, and therefore less need for cooling airflow. Other factors that play into this equation include whether the printer has a heated chamber and whether the hotend is mounted to a conductive (metal) surface, or a plastic adapter, among other things.
What parts do I need to upgrade a Prusa 3D printer with a Mosquito™ Hotend?
The Mosquito™ can work with the stock heater, thermistor, and fan that already come on your Prusa 3D printer. Therefore, to upgrade to a Mosquito™, all you would need is the hotend itself, some Boron Nitride thermal paste to properly seat the heater ...
Mosquito™ vs. Mosquito™ Magnum, which one should I get?
The Mosquito™ Magnum has the same high temperature performance, small form factor, and light weight as the standard Mosquito™ Hotend, but offers a much higher volumetric flow rate of melted plastic. If you routinely print with nozzle sizes of 0.6 mm ...
What parts do I need to upgrade a Craftbot Plus Pro 3D printer with a Mosquito™ Hotend?
We recommend using the Mosquito™ with the stock heater, thermistor and fans that already come on your Craftbot 3D printer. Therefore, to upgrade to a Mosquito™, all you would need is the hotend itself, some Boron Nitride thermal paste to properly ...
Mosquito™ Magnum+ Dual Heater Configuration for RepRapFirmware 3.0+
The first method of configuring a dual heater Mosquito™ Magnum+ is using two heaters in parallel, acting as a single heater with double the power. The second configuration involves each heater being tied to its own extruder heater output and then ...
Does the direction of air flow from the hotend cooling fan matter?
The sticker on our fan should face the hotend, with the air flow directed toward the heat sink. If you are using a dual-extrusion setup where the two fans are in line with each other, then they will need to be oriented in a way where one fan is ...
