Just had a closer look on the picture. The wing is made as a three part. A middle section and two tips, left and right. The middle part is pure white, the tips blueish.kostantin wrote: ↑Sun Dec 23, 2018 10:53 amGreetings,
I have serious doubts about this possibility.
Scanning, I don't believe that the scan is accurate enough, when it comes to the profile. We are talking of less then a tenth of a millimeter. There
a profiles that are extreme sensible at specific points.
No material I know is even close on stability to carbon. You have freaking bending and torsion forces on a wing. A printed wing with a profile thickness between
8-9% will make all type of fancy things when you edge the foil.
It is not even good enough to use the printed parts as a platform for profile testing. The plastic is too weak.
Usually you print with infill. That means that the printed parts will fill up with water in the areas where no plastic is.
Putting carbon or glass on a printed wing. None of the resins I know stick well neither on PLA, ABS or worse Polycarbonate. You will loose any benefits of
a correct printed profile.
Where I see sense in printed parts for a foil are mock ups to pull molds. Either as positive or negative, but only if you are aware that the plastic is getting weak again at 43°
How do they have fit together when printed ?
You can do a a quick reverse engineer on this using the guys fingers to find the profile thickness. To keep it simple use a profile thickness of 10% No way !
When you have a closer look you can see the milling lines from a CNC.
Sounds a little fishy to me.
By the way a wing with such a high rake will have torsion on the wing tips high as Trump tower.
As long as there are no other pictures I would call this story bogus.
