here is a rendering of the printed wing I have been designing. My idea is to create a rapid prototype/carbon fibre composite material which I can use in UAV applications. The concept is to be able to print the RP parts directly from CAD data and then cover in carbon fibre pre-preg. The use of RP allows quick design changes and iterations without tooling. The RP is used in the same way a structural foam would be used.This concept is for a UAV around the 20kg weight size, I'm not sure it would be possible to make it light enough for smaller UAV applications.........
I am hoping to produce the physical parts in the next few days. Part of the callenge is to create a lightweight structure that will build easily on the RP machines and something which will skin up ok in CF. I may need to do a couple of iterations before it is acceptable.
I'll post some pictures of the finished parts as soon as I have them....
