Boron Nitride Thermal Paste: Why do I need it and what are the benefits?

Boron Nitride is a compound that helps with heat conduction. We suggest using it on any surfaces that need to conduct heat. The most common areas that could benefit from Boron Nitride Paste are between the heater cartridge and the hotend, the temperature sensor and the hotend, and the nozzle and the hotend. Boron Nitride is great for the Mosquito® Hotend, but will also work nicely with any other all metal hotend. More information on how to properly use Boron Nitride Paste can be found here.


Do you have groove mounts available for the Mosquito®?

We’re not huge fans of the groove mount adapter system… but for those with a groove mount on their printers, we have a nice solution that mounts to the Mosquito® hotend.


I'm experiencing filament jams when printing PLA! Help!

By design, the Mosquito® hotend is created with more precision than the typical hotend. More precision leads to better prints, but also means some filament materials may require more finesse to dial in the settings just right. Check out this article on ensuring you've got the everything on your new hotend set up for success


I bought a Mosquito® hotend, now how do I get it on my printer?

We have a whole list of adapters you can print on our Adapters page, and are constantly adding more. If you choose to print an adapter, we suggest using a material with a heat deflection temperature above 90 °C (HDT>90 °C), such as ABS or Nylon to provide more rigidity at elevated printing temperatures. If your printer isn’t on that list, let us know and we’ll try to get one built. We also have a few all metal adapters for a variety of common printers.


I've got plastic residue all over my nozzle or hot block. How do I clean it off?

That sounds like a personal problem... Just kidding, we'll still help. We recommend cleaning the Vanadium™ Nozzles and Mosquito® or Copperhead™ Hot Blocks by either heating them up on your 3D printer or with a heat gun, then wiping off the plastic residue with a cotton swab. You can also bake off the residue in an oven or kiln (not one used for food consumption). 
We do not recommend using steel bristle brushes to clean Vanadium™ Nozzles, as they tend to leave behind material fragments that can generate rust on the surface of your nozzle. You can use a metal bristle brush, but then your nozzle will be ugly. And you will be sad.

Yes! It will allow you to reach higher temperatures, expanding the range of filaments you can print, and will help you reach normal operating temperatures faster. However, please check that your printer puts out enough power to support the heater before purchase!


I bought a Slice High Temp Thermistor. Now What?

The thermistor (temperature sensor) on your printer is dialed in with your printer’s control board. When installing any new thermistor, including Slice’s High Temperature Thermistors, you will need to ensure the proper settings are input into your firmware, and should run a PID tune on your controller. The RT table for both of the Slice High Temperature Thermistors is available here. Duet3D natively supports both Slice High Temperature Thermistors. Marlin 2.0 now supports both of the Slice High Temperature Thermistor. Select Thermistor #67 in settings for the 450°C variant and #5 for the 300°C variant. We are constantly working with other firmware developers to include the Slice thermistors out of the box.


I bought the Mosquito® hotend, but I don’t know what to do with the fan…

That’s a statement, not a question, but we’ll still answer it. The Mosquito® hotend can actually function without active cooling (a fan) when printing certain materials, 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 that I have the Mosquito®, what should my retraction settings be?

For direct drive extruders paired with the Mosquito® series of hotends, we recommend setting your retraction to the same distance as the diameter of the nozzle you are printing with. Ex: when printing with a 0.4 mm nozzle, set the retraction distance to 0.4 mm in your slicer. For bowden setups the length of the bowden tube heavily influences necessary retraction lengths, and will require some tuning. We recommend halving the retraction setting used with your previous hotend (before Mosquito® installation), and tuning from there.


Does the Mosquito® require special slicer settings?

The Mosquito® hotend does not require any special slicer settings, and works with any extrusion system, including multi-filament (mixing) systems such as the Prusa MMU or Palette 2 from Mosaic Manufacturing.


What is the mass of Mosquito® and Mosquito® Magnum?

The Mosquito® Hotend weighs 41g, while the Mosquito® Magnum is 45g, making the pair the lightest high-performance hotends available on the market.


How do you secure the temperature sensor and the heater cartridge in the Mosquito® Hot Block?

Boron Nitride (BN) Paste is required on the temperature sensor for accurate measurement. BN paste is also desirable on the heater cartridge and nozzle threads. The retaining screws on either end of the hot block prevent the heater and thermistor from pulling out.


Is there a maximum temperature rating for the Slice Engineering® 50W heater cartridges?

Both the 12V and 24V 50W heater cartridges are rated to 500°C. Actual achievable temperatures will vary based on a number of factors, including whether the heater is operating in an enclosed or open air 3D printer.

Does the direction of airflow from the hotend cooling fan matter?

The sticker on the fan should face the Mosquito® Hotend, with the air flow directed toward the heat sink.


Can I use the Mosquito® hotend with a threaded-style extruder?

We have an M6 threaded stem adapter that can be used with the common Mk7/8/9-style extruders, other M6 threaded extruders, or extruders with a 6 mm clearance hole.


What type of nozzles do the Mosquito™ and Copperhead™ Hotends use?

The Mosquito™ and Mosquito Magnum™ use the same nozzles - Rep Rap style (see Documentation page for drawings and STEP files)
