    High Temp Resin Nozzle RUN - Any interest?

    EDIT: FINAL VERSION IS UP FOR GRABS!!

    http://www.print3dforum.com/showthre...ll=1#post43003

    ------------------------

    Hi!

    Given we got a Form2 few months ago, i just realized I could print resin nozzles using the High Temperature resin Formlabs offers, which is supposed to withstand up to 286C

    Given we barely print at max. 250, this shouldnt be a problem and we would have the BEST replacement (even better than stock ones) for the nozzle heads.

    We could even CAD one with the threaded fitting for those of you who would like to avoid drilling in (un)certain angles

    How does that sound?

    If there's enough Interest I can go ahead and order the tank, resin and start doing betatestings

    How much do you think it will cost per nozzle?

    I'll make some numbers but it should be "relatively" cheap.

    FYI, Cube 3 prints ABS at 260.

    We're still good 20C below the max.

    I have used the Form 2 high temp. It is expensive and requires a dedicated tray (gets cloudy fast!)

    It is an acrylic based material. It will shatter. It does require additional UV curing (sunshine is best).

    Having said all that, it should work if the threads are already built in. Tapping this material risks cracks.

    The print head I designed snaps together. Wouldn't the clips break real easy?

    I can certainly test for endurance, of course.

    I do get a dedicated tray for every type of resin, yes.

    And got my own cure station too But sun is also often available here

    OK so accounting for the resin lost in the supports, tank wear, cure time, etc. cost per pair (aka 1 nozzle + 1 cover) as this:




    is about 4,5eur.

    Given I could do several per bed (as you may know resin takes almost the same time to print ONE item per bed than 100 per bed), I could do with 4eur per pair.

    Of course I still need to stock the HT resin and do some tests for reliability.


    If in the meantime you want to propose any optimization or update in the design, please do so. As I see it, it's quite faithful to the original part plus the threaded hole, but as always, we're a big family here, helping each other and everyone!


    So let's talk about it!

    The handle was designed to be printed without supports. Because of this, it's kind of small. Would you like to see a longer handle to make it easier to twist on? If so, give me a simple drawing if you can of what you think it should look like. Keep in mind it can't be taller or lower because it has to fit in the channel of the printer.
