3D Printed Valve Part Helps Prevent Cavitation | The Cool Parts Show #56

[@studioeffects]

The Cool Parts Show has become one of my favorite shows to watch, keep up the great work!

[@bunnypeople]

Would love to see a transparent operational version of this!

[@EmilDeadPro]

Cavitation is such a pain in the a** to workaround. Happy to See relatively simple solitions!

Looks so organic, alien & futuristic. I love the design.

Hexagonal discretization is always best😍 Love the design!

Wouldn't this be the exact opposite of the faucet aerator? (6:57) I'm surprised that there doesn't appear to be post- processing to improve the surface finish... I get that it's a restrictor, but they did mention using the honeycomb to maximize flow. Speaking of flow, who else expected Destin to pop up and talk about laminar flow at some point? This really seemed like the perfect opportunity for a collaboration. Thanks, as always, for bringing interesting examples of different industries making the most of 3D printing.

i'm surprised noone put it on r/laminarflowporn yet.

What an incredible show and incredible video. I'm very amazed about the use of 3d printing in areas related to cavitation and industrial valves and the best of all, it's not just a prototype, it is a commercial and available solution to alleviate those issues. Great content, I'm now subscribed. Keep doing the good work.

What about turns? Wouldn't that help deflect in the corners?

[@MrHoodi1981]

Fisher for long was not in favour of having a anti cavitation trim on a rotary valve as these are not used in high pressure drop applications. Interesting to see that there has been a change in philosophy and Fisher has agreed to a anti cavitation trim design on a rotary valve.

[@weeb3277]

what is it made out of? metal?

[@AdditiveManufacturing]

Yes, metal. Emerson produces the Cavitrol trim in stainless steel and cobalt chrome versions.

Bees could make tubes that long. All you have to do is gradually increase the space between frames but not so much they build a burr comb. I've seen double the normal from a novice going from 10 frames to 9 and leaving a gap. It was full of honey too, weighed near 20 pounds.

[@jogb9515]

The approximate cost would be interesting, otherwise great vid.

John Hart attributes his MS student Kailyn as using this part as a data point in her study of the economics of additive. (kzbin.info/www/bejne/e6fahXiGd86BlcU&feature=share at 32:17) 36 kg. 213 hours. 4 lasers

Why not injection casting is not used ?
