Topic: Any benefit to slightly faster post-nozzle cooling? Peltier Module/TEC
I could supply three peltier modules of unknown spec* if anyone wanted to test out a cooler airstream at the nozzle. Or if you have some other sort of cold air source maybe you can test that way. I simply noticed that industrial machines seem to run filament through a water bath but I typically want to avoid involving water with my equipment.
*(I can't recall what machine I got the modules from, I believe it was a string of 8-12 peltier modules per 48V supply, so 4V nominal I suppose and several amps of max power. These are probably 30-40W peltier modules, which of course suggests the power numbers to be off. They're 30mm square with a Ac resistance of ~0.22ohms)
If more than one person is interested, I can ship off two each to two different people. I just have a few of them and would I supply shipping of course. I probably won't buy the filastruder for a few days, nor would I get it for over a month, and I'm already curious what might be done with it.
Overall these are only worth $3-4 dollars each, but I'm hoping to entice someone, knowing there's no effort (or frankly obligation) to signing up for them.
I should add that you will need a DC power source for the peltier modules, a heatsink and fan for the hot end, and probably a shroud of some sort to direct the colder air at the filament. But the shroud might interfere with the filament, I don't know yet.
