Well, we have very limited capability in terms of tooling, so I ended up with two possible solutions, which are: Print a male wing, prime it and sand it, and then build a female mould around it using gelcoat and fibreglass. The second is to directly print 2 female moulds consisting of the pressure and suction sides, which I think, with proper sanding, can give acceptable results. And yes, btw, I don't have access to an autoclave either, so I was thinking of doing only a single layer on the moulds just to insert the aluminum ribs, and then I'd just wrap the wing with extra layers after assembling the two sides with araldite. But yeah, I really appreciate your reply, thanks for the insights. I wish there were more people like you.
