    As @mark tomlinson said, shouldn't be any noticeable wear. Now if you were a member of 3D Hubs and ran your printer on Bronzefil 24 hours a day 365 days a year then you should invest in a Stainless Steel nozzle, but you can buy an awful lot of brass nozzles for the cost of one SS.

    If the embedded material is harder than brass, ie stainless steel, iron, or CF, then you'd want to use a stainless nozzle. Otherwise brass is fine.

    I agree with this since long-term there has got to be some wear. I just have not yet seen any (but only 1 spool of each of those used though so far).

    Yes, I am using one now. That's the V6 nozzle. Frank

    i realize that this is quite off-topic, but what is the size of the fan that is cooling the hotend itself, is it 20mm?

    2.5 cm x 2.5 cm x 1 cm for the Hexagon.
    3 cm x 3 cm x 1 cm for the E3D-v6

    Here's the strange part, the 2.5 is rated at 12VAC .1A, the 3 is rated at 12VAC .08A Go figure. They both speak Chinese. Frank

    yoho thx for the sizes, also going to install a quiet 25mm fan, since the one on the robo stock is obnoxious

    Good luck finding a quiet 25 mm fan. Easier to find a 30 mm, that is why I modeled this part:

    Evercool makes a 30 mm but not sure if it is any quieter than the inexpensive Chinese fans, here: Evercool 30mm x 10mm 12v Fan EC3010M12CA

    Anybody tried the solid state cooling electronics like they use on those portable coolers?
    I am thinking about it. Just think, heat transfer without noise. _DSC0002.jpg
    Hay, they work on 12 VDC. Don't know the current draw, but I don't t think it is to bad.

    HAY, just think, if the Peltier unit was mounted between the hot end and cooling finned unit, around the heat break, No fan would be required. The 'wasted' heat from the Peltier unit would help heat the hot end and the other side of the Peltier unit would cool the finned unit. Think about it. No more clogs! Frank

    Wouldn't work, high temp peltier is only good to about 200°C.

    In physics, like life TANSTAAFL*

    If you think you found one, look again.

    we used to say the laws of thermodynamics boiled down to:
    1) you can't win
    2) you can't break even
    3) you can't get out of the game

    *(there ain't no such thing as a free lunch)

    How about installing the peltier in an intake duct to the fan? It would cool the air going into the fan and the duct would act as a muffler.
    The duct would have to be metal to act as a heat sink also. Frank
    If I can find the units I have laying around, I might try it. So many projects, so little time.

    That is at least a workable idea. I am not sure what impact colder air for the fan will have (I am sure it varies by filament type).
