    I've seen your new stainless steel nozzles.

    Please make 3mm versions, too! I WANT ONE :)
    Now that Colorfabb are releasing their XT-CF20, the need for steel nozzles will surely rise.

    Do you guys plan on making stainless steel versions of the Volcano nozzles?

    Also, the page for the stainless steel nozzles say that stainless steel nozzles slow down printing. Why is that? Does the maximum extrusion rate need to be turned down? Or do print speeds have to be slowed down?

    Stainless has a much, much worse thermal conductivity compared to brass, so the plastic cannot be melted as fast.

    Call it maximum extrusion or print speed, the two are related by nozzle size anyway.

    The site doesn't make any suggestions about how much slower printing should be with stainless steel nozzles. Also, if on a v6 the heater block is only heating the nozzle, could the poorer conductivity could be countered by raising the temperature?

    You can't do that because raising the temperature in any significant fashion would result in the filament overheating and degrading/carbonizing when the hotend was idle or traveling.

    As a general rule of thumb, stainless nozzles can print at 50-90% of the speed of brass nozzles.
