Posted · Help with Printing a RC Wing

Hello,

 

I am currently trying to print a thin walled RC wing using Cura 5.7.2. I have not finished modeling the internal structure of the wing but I wanted to test out slicing the outer surface.  I enabled the surface mode which gives me the desired thin wall print, however, the slicer is filling the top surface of the 3D print. I would like the top of the wing to be open so I can fit a servo there. Any suggestions on how to keep the print thin walled and have an open top? I am guessing the issue is because the top is slanted but I feel like it should still be able to finish the top without crossing over and filling the surface.

    I suspect you're correct there. Put simply, it's seeing that part as a side wall and not a roof because it's not flat. And by flat I mean "level on the Z axis" 🙃. You can achieve the same effect as printing in Surface mode by setting Infill > Infill Density to 0% and Walls > Wall Line Count to 1. And by "the same effect", side walls on "top" are included:

    So basically "working as intended, not expected". I think some 3D programs have functions that could hollow that out and essentially turn it in to a tube, which would be the effect you're looking for.

     

    I don't know how complicated putting a servo in is. If you can do it while it's still on the build plate, you could pause the print before it does the part that will be in the way, put the servo in, then resume the print.

     

    Then there's the brute force approach: those lines are going to put up about as much resistance as cotton candy where they got the mix wrong and it's 95% air. You could easily grab them with pliers, lever them out with a screwdriver (I have a toolkit of many destructive things) and then use wire cutters to cut the ends flat (and sand them flat if need be).
