@Dandiego, impressive work you are doing. To design things in fusion as complex as an aircraft is kind of daunting, isn´t it? I´m also in that road, but one thing that it stopping me is the postprocessing of the FDM prints, a pain in the ass.
Anyway, I saw the other day a youtube video of a guy that used printing resin to soften a FDM printed helmet and the results were great. The idea is that this resin is quite fluid, so it´s easy to have it covering the printing lines without loosing details, and it cures with the sun. I´ve not tried it myself yet, but I thought that it was worth mentioning.
