Printed Props

LohringMiller · Nov 11, 2024

I just got back some 3D printed props. They were printed in 17-4 PH stainless and cost around $7 each for a batch of 6. Since the price for 1 was close to the same I had several, slightly different 43 mm props with different pitch and cup dimensions made. My next props will have progressive pitch and a larger shaft hole. I have some cobalt drills coming to fix the slightly undersize holes in this batch.

Very nice Lohring! I may have posted this before but here is a strut I had printed in 17-4. Tough stuff! Holding onto those props to drill the hole out should be fun

I used Craftcloud. They get quotes from a lot of companies. The props were printed by a company in Shanghai. I set up a system in Fusion 360 for the design and will need to alter it to get progressive pitch. The advantage of a custom program is you can test minor changes to a base design to see what's best. The price for several props is less than one ABC or Octura blank. 17-4 PH is really strong and inexpensive to print. This should allow really thin blades,

These are the second things I had printed. I started with the fin for a 3D printed outboard lower unit.
