Tri-blade prop

thingiverse

I had a local prototype shop produce 8 of these props using the SLA process last year. A propeller solution was needed for one of our micro FPV machines, and this is what I ended up with. The SLA prints were nice quality at about $8.50 each but very fragile and not functional. Also they are too fine to be molded. Injection molding is probably the way to go but these are fun to play with. The center hole fits a 1mm shaft such as the common brushed motors. I say experiment with your particular printer and see what kind of quality you can get. I was impressed that they printed as well as they did, and made my wife a miniature wind turbine using one of these props.

I designed this model in AutoCAD, and Simplify3D sliced it for printing.
