Hi, I was wondering if someone ever tried cooling the hotend with peltier elements? I can imagine having two of them on both sides and reinforce hot transfer capacity with some thin copper sheets between the cooling ribs. Cheers
No, as discussed in your RepRap thread this doesn't work, because for every watt of heat a peltier moves, it adds 2 watts of its own heat - so you are left having to dissipate triple the heat. No advantage in this application, also has been posted about and discussed at length if you're interested in reading more.
