This is awesome. Going to be a decent sized build if that's the size of the Canard.
Yeah, I want to keep the wing loading down, and still be able to balance the plane. There's a ton of weight in the rear with this being a biplane. I really hope the amount needed for the nose won't make the plane overly heavy.
I assume you’re using Simplify 3D to slice with, and only printing single extrusion walls? My walls are all .4mm thick, and I set it to only print the perimeter wall. This way I can adjust the extrusion by layer so that the bottom and top layers are thicker where you have to glue it together (same as 3Dlabprint). If I make the walls any thinner, the slicer will have issues with curves.
It’s hard to see the offset layers you’re referring to from some of the images. Would you mind sharing a file for a small piece, so I could check it out in Fusion?
One more thing. I think you're using a Prusa Mk2 also. How do you get your thin wall prints to stay stuck to the bed? I usually have to use a thin layer of glue on the bed, but taller parts have issues occasionally. Do you know any tricks?

I'm using simplify 3D with multiple processes. My STL files are setup exactly how the 3DLabPrint stuff is. They probably have a more streamlined process to get their though. We both have zero thickness outer walls and a gap between internal and external spars.
So, I can do the first 3mm with double wall thickness, and the rest with a single perimeter just like theirs.
Here's a cross section. I'll see if I'm able to save and export a piece for examination in fusion. The file is incredibly complex though so don't get your hopes up.
It might be a bit of a pain to set things up this way, but I have some ideas I'm trying out on the upper wing to make it easier. I think it's worth it for complex shapes though. Early on I tried to have a set thickness for walls, but keeping it on advanced shapes was a bear in the end, and complex stuff often had slicer issues around curves.
And yeah, I'm using a Prusa. I also use glue stick for thin wall prints. If you run into any tall stuff that still gives you trouble, or have trailing edges that want to pull up, helper discs are great.
Just make some .2 mm high objects. They don't have to be round, but circles are easy. You can tie stuff together at the base that way, or increase surface area on troublesome points with a minimum of waste filament. It's also really easy to pull off the bottom of the part when it's done printing.
