small idea

i found a heatsink that i forgot about, so i thought i would see if it would help cool down the top part of my hot end. i will not be able to test it too well until my ramps board gets here, but here are some pictures of my idea.

i am not sure if it will help or not, but i thought it was worth a try. it is not touching the heating part nor is it touching the peek 



here i mounted a small fan i had to it. this is more a trial to see if it will help or not so i just hot glued it on for now

  1. The "all steel hot end" idea is similar, but uses stainless steel for the heater barrel because of the low heat conduction. Relative to brass, anyway.

    I suspect that with a brass barrel you'll just cool the whole thing down, essentially increasing the duty cycle of your heater.

    Maybe not though... Let us know!

  2. i was thinking the same thing too, so i will also try to move it farther and closer to the hot end and see how it behaves.

    i suspect for what i want to achieve,the farther the better.

    but i had it so i thought i would try it, no harm in trying any how.

  3. You don't NEED any of that but let me if know if/how it works.

    i like your work and design very much, i only got the idea from a forum chat on the reprap blogs, with a person who was having troubles printing in the heat in Australia. so please dont get me wrong i don't think yours needs much improvement,

    i just got the idea and thought it would be worth a try to see how it would affect it and just to see how much heat gets up there any how. when my new set of electronics arrives and i get them build i will do my best to log the temps at that point with and with out it up there. the more we know the better right.
