Print fan shroud/ duct at 90 degrees for strength

Postby walshlg » Tue Jul 12, 2016 1:29 am

The fan ducts are disturbingly flimsy. Part of the problem is because they are printed in a bad orientation : they are printed standing up so the print layers are horizontal when mounted, interlamellar strength is always the weakest in filament prints! Instead, lay them on their back, so the inner curve faces up and they will be much stronger.

I had to reprint mine as they fell apart because the layers weren't bonded well. They also forgot to remove the supports from the air duct.

Likewise I needed to replace one of the fan shrouds. Once I finally got the printer printing ABS correctly, I printed it out. When I examined the original, I noticed that it wasn't printed in the correct orientation to maximize strength. I laid the shroud down and printed it using standard quality with my white ABS (I really wish Raise would have some black ABS in stock sometime soon, I've been waiting what feels like forever). I was really impressed with the quality and feel of my newly printed fan shroud. When I looked again at the old one, I don't think that it was even printed on a Raise N1/N2/N2+. The quality is just worlds apart.

Hi Lyle,

Do you still keep the original fan shroud from us?? If you'd like to share a picture of the difference your new one and the original one from us, it will be great. I can use it to feedback to our factory.

Vicky,

Sorry for the delay. I took a couple of pictures to try and show some of the quality differences. I do think that some of this very much has to do with the orientation of the model when it was printed. I think having the fan ducts printed standing up results in a much weaker part. If it is printed without supports, then it also results in some of the quality issues as well. The white one is the one I printed in ABS using the standard settings for Raise ABS modified to print at 245 instead of 240.

I have been using my printer almost a month and only recently I found that my ducts still had support material attached to the bottom, I remove it and the airflow was greatly increased. It looks obvious, and still it eluded me for almost a month, I am sure that I am not the only that received ducts with support material.

Yep, several of us have ran into that, as seen above, also when you print out your new fan ducts, print them laying flat vs standing up.

Vicky, you might want to add "Support Still in Extruder Fan Ducts" to the FAQ.

I also had support material in mine on my N2. One of the fans snapped in two when I reached for something and happened to jab it with my fingertip. The other one had fallen apart shortly after receiving my machine.

I fixed both by removing them and gluing them back together. I haven't had to replace one yet, though.

Where is this file available? My duct broke the first time I removed it.

Fan (and shroud) is same on N1 and N2? I have an N1, but most of these files/prints/threads seem to say N2

It is the same.
N1 and N2 (Plus) extruder head design is the same.
