3D Printer – Quality Printing with Cooling Fans


How important is printing with cooling fans? Very important!

In this video I show the quality difference between printing with and without the cooling fans active. The results are confronting.

    Hi, can I bought the printed parts anywhere? Thanks, Gabor

  2. Seems like too much cooling would also be a bad thing, because that would prevent newly deposited plastic from fusing with already deposited plastic, which seems to be a problem that I am currently having. Part strength is also an important aspect of quality! I think my problem is that my printer is in an unheated garage. I put it there so that fumes don’t pollute the areas where we live. I’ve put a cardboard box over the printer to retain heat, but that does not seem to be enough :/ I’m hoping I don’t have to put much effort to solve my part strength problems… Suggestions, anyone?

  3. Just found your channel, I’m having immense issues with prints detaching after a while so I lose 2 hours work, heated bed, glass and tape, 2 years never worked

  4. Why are the ducts pointed at nozzle and not towards the bed? I would assume that pointing at nozzle will cool the hot end nozzle, which works against heating it?

  5. Just a beginner here, I read through the comments, both for and against cooling … But the video was simply superb… Great lighting and clarity… Thanks a lot!

    Your test is very useless sorry. We can see that with just 1 fan your T° is really too high. you just have to lower it. So you set your temperature to high it’s a waste of energy and above this you add 2 fans to waste even more energy. And we can see that you don’t respect the time beetween layers. In fact the only positive thing to adding fans is to reduce this value and print faster.

    To hot, and to fast, my prints come out great without fans, running at 195-200 heat, and anywhere from 20-40 mm/s, so for me the whole fan thing is a wast of time, and plastic, fine tune your machines thru settings of your slicer software, and will be just fine
