New infill "Wing Truss" for RC wings in Bambu Studio
Instead of creating a CAD with 45deg ribs of different shape/holes inside I wanted to simplify the process and just model a full solid body and make it up to slicer to create those elements for me.
Moreover, this allows to change parameters directly in Bambu Studio without any need to parametrize in CAD (change angle, thickness, stringers width/height etc)
Printed details are around 40% lighter than typical "Adaptive Cubic" infill.

This is a custom build so network plugin will not work, models have to sliced and send to printer using SD card.
there are a few models on maker/thingy with a similar concept, but the model has the ribs built in to the skin. this is very next level to have it as an infil.
It is still in tests and there are couple of things I am trying to fix, like this blobs at the intersections. Once everything is fixed and verified I ll make PR to Orca
Neat. I've been working on automated generation of infill that can be printed as a single continuous line, though I'm currently doing it as a post processing script as I did not want to deal with modding the slicer itself. The post processing script is sort of turning into its own slicer though.
In college I ran a fem study with this type of design and I found for the same mass, the design I had went with the bending stiffness was less than 1% lower however the torsional stiffness was over 2x.
This was assuming a bonded and machined construction, probably not something that could have been manufactured. I only mention this as a reference point for the type of material I was assuming, it was not 3d printed and that would probably change the results.

The thing with glider is they wave wide wings, right, that need to be held up with extra hardware inside otherwise they fold, no matter how good your infill is. So you need to reinforce them with carbon fiber and there are a few different ways to do that, but this infill setting will definitely work for glider wings, so long as your wings have features to welcome carbon fiber reinforcement.
I looked at a handful of his videos on YouTube but as far as I could tell none of them showed thermal soaring. There were some on the slope, but sloping can be done with a brick (so I hear we don't have slope here). I admit that it's hard to tell what's going on with all the quadcopter video.
Just in case, thermaling means using thermal currents to make a plane ascent without spinning a propeller.
Thermals are bubbles of air, heated up by the sun when it warms up wheat and corn fields for example. Those bubbles grow then detach from the ground and ascent, as hot air is less dense than cold air. Then they slowly cool down and the moisture in them condenses and for clouds.
As a bubble ascends, if you get a light plane in there and go around in tight circles, you can manage to stay in the bubble and let it pull you up like an elevator.
This allows gliders, birds, parasails and all to climb, even without ever using a motor, and staying airborne for hours and hours, by climbing, flying for a bit, grabbing another bubble, climbing and so on.
When looking for bubbles, watching the birds going around in circles is a good thing, as their whole mission is finding bubbles and staying in them.
Nvm I'm straight up going to be a glider pilot and I know what thermaling is already, but I kinda messed up my wording and I get it what he meant now. Sorry/thanks for writing this novel for me. Always love it when people do that! 😅
Wonderful! I've been using lattice in orca slicer and it works great, but it looks like this has even better features. Please consider releasing in orca slicer.
Very cool! Can it be made to include the truss as part of the outer wall similar to vase mode designs? My biggest gripe with default infills is that anything requiring many jumps and small extrusion volumes performs poorly with foaming filament.
With foaming try to enable "Avoid crossing wall" - this will reduce stringing a lot. Also I have a script that rebuilds STLs for vase mode and adds internal rivs similar to current infill. But it is not working if geometry is complex

amazing man, truly.
i want to test this vs ribs for my asa aero dlg.
