Austin's Foil Build


#1

Here are the files to my Fully 3D printed Foil and Mast. I have many pictures I can post upon request of angles I printed them.

Mast 1 (top part of mast with Mount)
Mast 2 (middle part of mast)
Mast 3 ( bottom part of mast)
Mast 23 ( mast 2 and 3 together held together for better support while printing)

Mast 23 worked the best on my CR-10

Foil wing Left and Right I printed countless ways and it kept failing until I tried this angle.

Austin, I really like your design! I looked at your library of parts on grabcad and it wasn’t immediately obvious to me which of these I would need to print and equally important how you envision assembling them together. Did you fiberglass or carbon fiber your design? Or plan to? Thx!


#3

I plan on fiberglassing all of it together. Right now its just glued together. There are three pieces to print for the Mast (Mast 1,2,3)
and the foil has 3 or 4 parts to print depending on what type of printer you are using. My CR-10 has a decent print box so I can print half of the front of the foil at one time

!

it’s nice to see someone else 3d printing the same mast and foil as myself. best of luck.


#5

Have you had the opportunity to test it yet?

@Atriay11, that is great, thank you.

My son @axgib and I are starting printing your mast. About 12 hours overnight for the first piece below.

Which glue have you used please to glue together the various sections ?

We printed on our “old” now Cr-10 with the following settings :
PLA at 225 degrees
Glass at 50 degrees
Layers height at 0.3mm

It is coming perfect at the first trial.

Plan will be to cover it with carbon layers

Cheers

To be honest I don’t thing this 3D printed setup will work. How do you handle the push force in the mast? Carbon or Glas is not good in taking those. For the fuselage I also think it will break. Last year I made one out of 20x20mm wood, an it broke immediately

Atriay11, we have finished printing the mast (mast2+3 took 23 hours !), now printing the fuselage for only a couple of hours.

We are surprised by the length of the mast, ain’t for rookies ! :smile: So we were thinking about keeping only the first 2 parts, and forget about the third part so that it is reasonably easier to start experimenting and flying. Mechanic efforts will be weaker then too.


#10

Glad to hear its coming out well! Right now I have gorilla super glue holing the parts together before glassing it. I’m excited to hear you are covering it with carbon layers. I’d love to see how that turns out, please share some pictures. If you plan to shorten the mast length I would skip MAST2, because Mast 3 has a non hollow bottom that will help adhere to the fuselage better.


#11

nope, just finished carbon fibering, 4 layers of fiberglass one layer of carbon

Does any 3d printed work?
