New Mosquito Hotend



  • Hey Everyone,
    We were able to get our hands on the new Mosquito hotend from Slice Engineering at MRRF. We will be running extensive testing on it over the next couple weeks. We want to know what you guys would like us to test?

    Run Down
    .8 nozzle (able to withstand abrasive material also compatible with e3d style nozzles)
    450C thermistor (with it being a thermistor we should no longer need a daughter board for high temps)
    50 watt heater cartridge

    What we will be testing as of now
    Carbon Fiber Reinforced
    Ultem (Priority)
    Polycarb (Priority)
    Nylon (Priority)
    ABS
    PETG
    PLA

    Our first task it designing a grove mount adapter to fit most extruders on the market, once complete we will post it hear for others to use. We will also be designing one for the Nimble.

    Please let us know what you want us to test and we will be creating a list.

    It was great to meet you guys at the show!



  • @T3P3Tony:

    It was great to meet you guys at the show!

    It was great to meet you as well, cant wait to do it all again next year!



  • This hotend looks great! However, the transition zone seems very long… How does it work with flexible filament, like Filaflex?

    A thermistor is generally a poor choice for wide temperature ranges. It's likely to be very inaccurate at both low temperatures (perhaps leading to "thermistor disconnected" errors) and at high temperatures. If you want to avoid using a daughter board, I suggest a PT1000 instead, if you can find one rated to 450C.

    Slice Engineering claim it is accurate up to 450c, I'll be running a pt100 next to the hotend to check accuracy.



  • This image was on the Slice documentation website but it has since been taken down. (The image didn't show the whole thermistor table, so maybe that's why?)



  • Just looking at the general design (which looks good to me) and the effectiveness of the heat break arrangement, I'd question the need for a 50 Watt heater. I appreciate that the design is about achieving high temperatures (although I'm not quite sure why 450deg C is deemed necessary) but given the low looking thermal mass, is a 50 Watt heater cartridge really needed? Based on my own testing with high wattage heaters, they can be difficult to control and maintain a steady temperature. It would interesting to know if the same high temperature could be achieved with a lower wattage heater.



  • Was one of the more talked about and interesting new items at MRRF, and I'd love to get my hands on one to test. The guys have been very responsive and engaging to talk to.



  • Dan says the thermistor table was taken down because it wouldn't display correctly on their site. They're working on that. In the meantime, if you want a copy, email dan@sliceengineering.com if you'd like a copy of the whole thing.

    I've invited him to join in on the conversation here as well.
