Only the motor mount left and we will end up with a weight reduction of 500 grams from the previous design

Given the scale of this aircraft, I've split the fuselage into printed sections and now moving on to the wing root. My priority is minimizing weight without compromising structural integrity. The aircraft features a 3-meter wingspan with an inverted V-tail twin-boom configuration and a wing loading of 6 kg/m². I'd welcome any suggestions for improving the wing root design given these constraints

Edit: Also the final image doesn't include the cutout from the wing root part. It was for a magnetic cover but the final image is old so it doesn't include it.

took a lot of time playing with the slicer but i got it down to 170 grams. also added air holes at the front to prevent electronics from over heating. really thinking about adding gyro stabilisation since it’s gonna end up having a 3 meter wing span. what do you guys think?

I am trying to print the front fuselage and I am trying to conserve strength while keeping minimum weight. I have this truss rib structure (maybe you have seen the other post), so I added modifiers to where the ribs meet the walls. My original problem was that without the modifiers the slicer wouldn't recognize the ribs all the way to the outer wall, so I just added extra walls to where I need them as seen in the picture above. Now the new problem is that I wont be printing continuously in an unbroken path. In the picture you can see how there is a cutoff from the modified rib and the walls, I want to make them connected rather than split off like that. So how do I do that? I also already tried to just boolean the ribs and the walls and then bring it to the slicer but still didn't work.

Anyone with experience with this? I dont know how much is good. 3 meter wing span with an estimated AUW of 2-4 kg

I have saved a little over 500 grams off of the original design for the fuselage of this UAV project we have going on here. It's gonna have a 3 meter wing span, but the main thing I am worried about is the print cracking and breaking under the 540 gram battery because of me setting the wall loop to 1. I am at 5% infill with 2D lattice. When I give myself two wall loops the weight of just the front section goes from 112.89 g to 160g. So I am still debating if it's even worth it since I will probably just add back an extra 200 grams for the whole fuselage. Whats yalls take on this? (Old Design last photo, and weighed about 1100 grams)

So I completely redesigned the fuselage and got it to 500 grams, with an original of 1100 grams :). The last image is the old design.

i am gonna end up with a 3 meter wing span. what infill should I print with? i put the wing in the slicer and it came out at 1.1 kg. i am trying to make the whole thing as light as possible while keeping structural integrity.

i 3d printed the whole fuselage in ASA filament, and it’s all supported by a single carbon fiber rod. without electronics it weighs 1.2 kg. I was planning on doing a 3 meter wingspan but then I put all the parts into the slicer and a single wing comes out at 1.1 kg. in the end we are looking at an estimated 4 kg, so how do I go lower? how can I compensate?

So far I have 3d printed the whole fuselage with ASA to weigh around 1kg. The wingspan is about 3 meters long and I am planning on 3d printing those too. I have got an 800 kv 4250 brushless motor, 4s 6500 mah Lipo, 100 amp esc, and a 3 blade 12x6 prop. Any recommendations?
