Hello netizens of Lemmy, while printing this single wall wing segment i ran into a problem with significant bulging around the middle. This causes the segments to not fit onto the frame or each other. If anyone has ideas on how to fix this, please share. At this point i’m pretty desperate and willing to try just about anything.
Larger nozzle.
Dead-ass. It will be heavier but single wall printing almost never goes well unless it’s a vasemode part or you’re using a minimum 0.8mm nozzle. Generally even single wall parts I try to do 2 nozzles wide at 0.6 else they will warp and buckle under their own weight.
Thanks, but unfortunately i only have a 0.2 nozzle. Solid walls beyond 0.5mm in thickness border on impractical for an airplane anyway. I had success printing walls as thin as 0.15mm, but that only works with at least a little bit of infill, if i have to make it heavier i would rather just do that.
Depending on how much effort you’re willing to put in, I would suggest switching material.
Use fiber reinforced plastic.
The process can be done at home, though you may need some practice. You can print the shape you want with a thicker wall thickness and then use that as a negative. You get the best results if you have a compressor and can use vaccum techniques to get the excess plastic out of the material. This will put you in the thickness space you want, and it will still work, and you don’t have warping problems.
Before you mentioned that it’s for an airplane this made me think of the extra structure Tom Stanton added into his single-walled wing foils. He’s using a foaming filament so that changes things I guess, but could this work for you? Apologies if you’ve already seen this https://www.youtube.com/watch?v=XPXN0QejqM0&t=555
