Thermoelectric cooling

Recommended Posts

Posted · Thermoelectric cooling

Just wanted to know if anyone tried using a thermoelectric board to cool the hot end "cold area", these semiconductor boards can go down below 0C and are very easy to use, just plug the 12v supply.

it is possible to use a round one - http://www.ebay.com/itm/Annulus-10-26mm-TES1-04930-Thermoelectric-Cooler-Peltier-Plate-Module-C0503-/290891565455?pt=LH_DefaultDomain_0&hash=item43ba7d098f

did anyone tried it :)?

You still need to cool the hot side of the peltier. Also, creating a larger than necessary temperature difference is counter productive IMHO. The hotend has to be able to dump even more heat into the filament to melt it that way.

A simple fan is fine. You are only trying to cool it below 80C. Which is quite hot.

I've often wondered if there might not be a role for it in the print cooling fan system though... in order to cool and solidify the extrusion as quickly as possible....
