Infill in 3d-printed Wings - my honest opinion.

In the last time it seems there´s some kind of trend to use Infill as a supportstructure in 3d-printable planedesings as a substitute for fixed, definded ribs.

This is my honest opinion about it, and what i think are the pro´s and con´s of infill in 3d-printed planes.

I´m aware there are already a lot of successfull designs utilizing infill, allthough i think there´s room for discussion, so feel free to comment below and tell me your opinion.

Good points, maybe it would be nice if it was possible to find a compromise on the wings design. For example a small part of the leading edge of the wing, just in front of the front spar can be printed with infill and the rest printed normally, This at least can serve as extra impact resistance.

Very helpful. Thank you for posting that

Ive had success lately with using gyroid modifiers (in bambu slicer) in certain critical areas only. Its been strong and light. Perhaps still not as ideal the your preferred difficult method, but much easier and allows modification in future prints. Ive been making the bottom of the fuselage around 10% and having a 10mm cross section of gyroid infill on the top of the fuselage. For the wings, i make 'spars' of high infill in diagonal patterns. Im too stubborn to spend my time designing proper support haha. Now im probably spending as much time figuring out how to use modifiers effectively. Thanks for your video

Well done. Love the hamster. Oh mine gott! Or.. why not print a shell and spray foam inside the two walls? Not seen anybody try that trick yet.

I'm trying to print your Zet Zwo, but I have an Ender3D Pro printer. Would you have the .3MF files for the Ender?

I have not tried, but, if using PW-PLA I suppose after using the slicer filled wing you could attach a drill bit and bore a hole and then very slowly to insert a carbon fibre rod with some slow setting epoxy. Similarly, push rods from stiff bike spokes in the wing to get your flaps operational should easily penetrate the slicer filled wing.

I don't like the widely adopted design of wing structure for 3D printed RC planes either. I'm designing a small RC plane and am planning to print the wings at a 45 degree sweep angle meaning I can still design the wing structure the conventional way and have ribs running length ways. I'm not sure if anyone has done this, haven't seen any videos but I don't see how it wouldn't work. I will need to slice the wings up in slightly undesirable places but the wingspan is only about 600mm so it shouldn't matter.

I beg to differ but the future will prove whoever is right right
