Industrial Grade Mosquito Hotend by Slice Engineering | Best Professional 3D Printer Upgrade | Eliminate Heat Creep | Print PEEK & PC | Bimetallic Heat Break | Stops Clogging | Improve Resolution

Actually I have two mosquitos this one (impulse buy) which is in the box and another one that is on my Voron. I can see the difference when using the mosquito. But I only used the mosquito vs the plain old aluminum heatblock from artillery 3d printers with a titanium or bi metal heatbreak.So obviously the mosquito should be better. I used this many hundreds of hours 3d printing on artillery swx1 and the prints looked good. However the problems with this mosquito is the heatblock shape / design. Recently I became very fond of the Volcano v2 heatblock - which is also plated copper just like the mosquito one and only $10-$20. I am not sure how much a brand name volcano v2 costs, but the ones for $10-20 get the job done quite well. in addition the v2 volcano is hot swappable on the artillery 3d printer. never had that hornet so I don't know but that clearly is for rivaling the creality shmeality ender bender. Anywho, a $20-$30 upgrade vs $150 is always a winner in many peoples books. in addition slice doesn't even bothers to make a heatbreak that would allow for their copperhead or anything to be hot swappable no additional add-ons for artillery. So they are being uncool here, they should think about that. In addition because of the way the heat cartridge is mounted as well as the thermistor - the silicone socks have no way of covering the entire heatblock properly like the volcano v2. Therefore when you have failed 3d prints that looses bed adhesion they will wrap themselves up on that $170 beauty rendering to crap. So I think slice should redesign that heatblock into a shape that can take a silicone sock on it. A silicone sock that doesn't need any side holes or any holes therefore truly protecting that heatblock - but then again if you lose it in a failed 3d print because it get engulfed in plastic you may buy another one - so why would they want to make you life easier? But for that there is the volcomosq. yea a volcano inspired heatblock that works on the mosquito heatsink. and is funny is not even a slice design.

This is a very well made hotend. I had a rocky start with it at first, here is how i fixed it. I bought this under the impression it would fit my Creality CR-X PRO (same head carriage as CR-10). It did not fit. The mounting holes were M2.5 (not M3). They were spaced wider than the printer mounts. And the dual extrusion mixing head did not fit atop. I thought about 3D printing an adapter but I figured that will cause two new problems. ONE, it will prevent me from using dual extrusion feature which I do not want to give up. And two, plastic parts up against a hotend sounded like a bad idea.I was going to return it but then I found this company called katya ironworks. They make custom CNC parts for 3D printers and the like. I found them via ebay but they also have a website at katyaironworks.com. I chatted with KI and she was very kind and knowledgeable. In a couple weeks I got a CNC machined adapter. I am amazed they actually made the adapter from 17-4 PH stainless steel. That is heavy duty and will last forever, probably outlast the hotend. It fit like a glove and the hotend was then rock solid. I have never seen a creality hotend to be so rigid. And it can now feed two filaments. Better yet, katya ironworks folks designed my adapter to be adjustable so you can move the hotend up or down with respect to carriage (as in without moving Z axis), making it a breeze to setup the touch probe and level the table. I think this is an option so you may need to ask about it. And now I am able to enjoy this hotend. For the price of this hotend one may expect adapters are included but with so many different printers I would say a custom setup is best.

The hot end itself is amazing. Quick swap of the nozzle if needed, design means no clogs.Unfortunately my first delivery was horribly used and repackaged as new. Burnt filament all overQuick replacement was made and now I’m up and running with a shiny new hotend

Firstly, this is a hotend that is not really plug and play. I bought this for its ability to print a variety of materials. regarding the patent thing.. I honestly don't know anything about it.. and I don't care. This is a review about the hotend itself. People shouldn't be using this as a forum to communicate their grievances with the company.It will clog, but it clogs way less than most of hotends I have used. Be sure to get the fan to help prevent heat travel. The hotend works great with the fan and Bondtech extruder that is designed to work with it. I know that the mosquito is a proven design and that's what I was looking for. It's expensive and is not user friendly. I did not get a metal mount.. rather, I used my resin printer to pop out a mount for the ender 3 that it is on at the moment. If you get the bondtech extruder, make sure you reset the esteps for the extruder in software.. my previous was x4, so I needed to set the esteps to 400 up from 100.

Very surprised that for almost 200 dollars you don't even get a nozzle or heat sock with this. Only lollipops which is dumb

I have been using it for 2 years, and due to me doing one handed nozzle changes on cold. That was a bit too much torque. So i recommend preheating to about a hundred C. With that out of the way, this is a fantastic hotend, that made me forget about PTFE changes and mase my i3 mk3 a rock solid reliability champ. You can also lower retraction lenghth. Best part is that i have no trouble printing ASA, and more conventional plastics at awesome flowrates (>22). And at 27 for PLA. Their nozzles are also great, btw. Highly recommended time-saver for a advanced hobbyists and professionals.

These are great quality hotends. They are extremely durable, easy to use, and very versatile.

this has the very best heat break shown in thermal vision, available. Clogs WAAAY less, epic prints.
