RC Plane Wing/Airfoil study

thingiverse

UPDATE: 18 April 2017: I should add in a caveat: This design is eventually to be used on a 1.8m wingspan aircraft. The v21 idea won't work. A single line thickness for internal spars is way too flimsy. Next design to come shortly. I wanted to test modeling up some RC plane wings in a similar fashion that 3DLabPrint designs theirs, only better. I wanted to design them in such a way that it didn't require expensive slicing software, or very odd slicer settings. I think a single layer wing skin thickness is just too fragile. 3DLabPrint seems to use a single perimeter for wing skin and 2 perimeters for internal support. I'm testing to see if 2 wing skins and a single for internal support nets a better performing wing. Yes, it will probably weigh more, but by how much? The v4 file has double perimeters on both the wing skins and internal structure. Also, the internal spars are purely straight, no deviation. The v21 file has internal spars that lay across one another. I don't feel curved spars really do anything but add aesthetics. More files/tests to come! Print Settings Printer: BazBot Rafts: No Supports: No Resolution: 0.2 Infill: irrelevant Notes: No crazy weird settings required. There are some notes that should be useful: nozzle: 0.4 perimeter line width: 0.49 This should give you a "skin" thickness of 2 perimeters, and the internal supports 1 perimeter on the v21 file.
