here are a couple discussion:

Thanks for the link :slightly_smiling_face:

Some advancement on the build :


#23


#24

Sleek looking setup mate! Is the blue part printed then painted black p


#26

Thanks, it’s CNC machined in high density polystyrene


#27

I finally found a good way to put some pressure on the fiber inside my tube and get the perfect shape on the wing side:

using a bicycle tube :


#28

Got a new 3D printer :heart_eyes:






#29

Impressive propeller !
Which 3D printer did you use ?


#30

First pic … i would guess: photon? , how long to print this part ?


#31

Very good printing quality, well done


#32

The printer is anycubic photon. I’m really happy with the quality, the only drawbacks are :

  • it’s really smelly when i print (worse than PLA on a regular 3d printer)
  • it’s dirty work to take the part out and clean them
  • it’s dirty work to clean the printer (it takes approx. 30 minutes)
  • the build area is small (65mm×115mm×155mm)

Those parts have 0.05mm layers and quality is crazy good ! It took 3 hours for the black part and 4 hours for the green parts. You can print them all on the same build plate in 4 hours (build time depends on height and not of the number of parts).


#33

Strength wise, how does it compare to PLA on a std printer?


#34

Parts are really strong compared to FDM printers. It’s perfect to make thin parts like remote enclosures.


#35

I bought this printer for small parts and watchmaking prototyping purpose :

Currently building a nice full carbon fiber watch :slight_smile:

That’s why my efoil build is so slow, too much side projects :sweat_smile:


#36

That looks amazing! The printers not that expensive, but the build volume is tiny. Whats the cost to print compared to an FDM?


#37

good work,
can you share the link for the propeller?


#38

@Jezza yes got mine for 406€ with 2.25 liters resin on aliexpress shipped from Germany to France in 1 week. 1 Liter (1kg) is 50-60€

@philippe not sure i want to share the file because i copied Flying Rodeo’s idea. I made it myself because i don’t want to spend so much for a propeller


#39

Your next challenge is to copy the Lift folding prop then :wink:


#40

I think it’s not a big challenge, just need some dimensions (pitch, height, radius). I imagine the blades are coming out thanks to rotating inertia? or is it a hidden mechanism that push them out ?


#41

Yeah I would imagine so… Here are a couple of images of others that show some interesting techniques: http://www.nauticexpo.com/prod/seahawk/product-22578-56006.html
