Thin walls, missing details, printing an airfoil

Bambu Lab Software Bambu Studio

Hey,

Took me hours to figure out, so I’m leaving this here as I have not seen this answered here.

I’m trying to print an airfoil for an RC plane. Those typically print on a single wall loop and very finetuned shells. I now had an issue where the wing would slice fine on prusa, but not on Bambu Studio.

I found out that my issue with “removed detail” was indeed the “Slice gap closing radius” option (maybe along with other options, I’m not sure - this was the one that made it work all of a sudden :D):

Setting it to 0 gave a proper slice. This is a slice WITH the proper setting (0):

And this is one WITHOUT the setting (default 0.049):

As you can see there are plenty of walls missing (e.g. connecting the two rectangular internal strucutre), and all the little “ramps” that support the internal structure as well.

As I said. Not needing any help anymore (took me a while to figure out how to post here as well :D), just leaving for others with the same issue.

Best, Markus

That should make it into their Wiki…

I do a lot of solid fakes using this method in vase mode but once I got it working never really wondered much about the gap setting.
But I saw quite a help requests over the time where people struggled with this issue.
I just solved it by creating a dedicated print profile for it and then forgot all about the initial hassles :frowning:

Out of curiosity, where did you get the plane model? I’m designing my own since all the ones I’ve found online cost money

Go join and ask in RCGroups.com. There’s quite a bit of discussion on 3D printed RC models.

The model in this post is actually a bought one, yes. Over time I found out that the few euros are well spent if you actually want to fly this thing more than one or two times :slight_smile:

Edit: It was this one: DG-600 Jetpower – 3DLabPrint

Buying the model in this case was rather cheap compared to the other things I needed to complete it xD
