Hey guys, check out this video I made on how to design a wing section using fusion 360. The part that has been designed can be sliced with any slicer in the market.

Hi, good work there. I have a question though, instead of creating a wing skin and then creating the internal support grid and then running a boolean through them, can't one just design the wing geometry as solid and let the slicer handle the internal geometry.

Most slicers today have gyroid and hexagonal infill geometries by default, I feel that's more suited for the application.

What do you think?

Hey Bilal,

That's the exact same thing that ran through my mind when I printed my first 3D printed aircraft. The AUW the design was built to handle was 1.1kg but it ended being 1.6kg, resulting in a very highly loaded wing and a super fast aircraft.

The section I printed above ended up being 34g without the weight reduction holes and 29g with it. The same section printed with 5% hexagonal infill ended up being 49g which is significantly heavier. Any lower an infill led to unsatisfactory results.

If you look at 3DLabs aircrafts, they all have a similar internal structure for the reason of weight reduction.
