This is the first I've heard of foaming PLA, definitely have to check that out.
Did you do the whole airplane with a small printer like the A1 / A1 mini? I would love to print airfoils but I'm struggling to imagine a way to link individual prints together in a way that preserves stiffness. My 100cm wing would need 10x (10x10cm) printed parts somehow attached to one another.
Until I figure this out it's foamboard building for the type of airplanes I want to build (glider)
Yeah I printed one of the Titan Dynamics airframes (before they closed up at access for the hobby market) on a Prusa MK3S using foaming PLA and CF spars. The fuselage came out in three prints, the wings as one print each, and then the two wing tip extensions got combined into one print.
It would definitely have been tight on an A1 mini but the full size A1 would work great for sure.
Definitely! I would have done the same but it was my first time working with the Foaming PLA filament and didn’t want to waste too much of it if the print failed.
A1, 256 x 256 mm lets me print these wings in four sections (including a double walled thin section for the boom mounts). With a high AR glider you'd probably need a few more. Carbon fiber spars + CA glue will do the trick for attaching them
