Resolving cooling issues with your prints
I had to remove my cooling fan recently as I had accidentally broken the fan blade, I foolishly left the fan running while trying to take apart my extruder because it had a blockage in the nozzle and then snapped!
New fan ordered and is on the way, So I thought to myself what difference will it make to my prints? I was intrigued by this so I decided I was going to attempt to print this Easter Island head without the fan in place, to experiment and see how drastic the final results are.
As you can see from the picture above on the left hand side the layering has left some ugly scars on the back of this statue and It gets worse.
Even with generated supports on the overhangs you can see evidence that finer detail around the statues brow, nose and ear have left scaring on and the layers appear to be less even. This is caused by the plastic not being allowed enough time to cool during the print, as the layer remains soft the extruder passes over with the next layer of plastic causing the lower layers to distort and leave non uniform layer that give the statue an ugly finish.
So I decided to re print this same statue, but this time with a desk fan in place on the lowest setting.
And here is the result! A noticeable improvement in quality.
Improved detail around the brow, nose and ears and an almost perfect print if it didn’t have a slight z-axis wobble.
So not a bad for a lazy fix or until a new cooling fan arrives! Tell us what you think, have you done anything similar? comment below!
