Your designs are so good. I really think you should be getting more views than what you get! I am glad that you posted again!

Interesting design. I'd guess, another viable strategy would be to design it in a way where low quality of overhang surfaces doesn't matter. For example, instead of making the valve ball in a ball shape, make it flat with concentric rings on it (shaped like WW on a cut) and the same on the matching surface. Then the sealing could be done by sticking the sloped surfaces to each other while the overhangs could be left with some free space without their low quality affecting the sealing. Also, there would be greater sealing surface and stronger action towards these surfaces matching.

@arthurmoore9488

That was my thought as well. Use a shape where it's okay if the thing is a blob of metal. Then, "just" use high pressure to form it appropriately. Another alternative is to design the part in a way that the check valve has a sprue coming out the end. That springy one looks like it was designed to be drilled out. Yes, it's not print in place, but it's also not using acid.

Alternatively or additionally, there's a process done with automotive systems that uses an abrasive putty forced through the system to polish internal surfaces for coolant and exhaust systems. Could also electrochemically plate internal surfaces with a softer metal like copper better able to form a mating surface. Maybe even mix and match approaches.

OMG, you're back! So glad - you make awesome designs.

I would say if you need a 3D printed check valve in your component, design the component so you have a route to drill out the supports, and fill that service port with a high strength metal epoxy, bung, or a weld after the supports are gone and just let the channel hold fluid. With the cantilever design, it looks like you can fill some of the support area with a flexible material, and get more holding power. I would also look at automatic transmissions, they are full of check valves, and they work by integrating the check valves into a valve body which is just basically just a complex machined metal plate, that integrates into the transmission's design; they use little metal, plastic, or silicone balls, sometimes with springs or connecting dogs, that can often be adjusted to alter the transmission functions.

Very nice project. I like the approach because it can be used as part of a larger system.

When it comes to leak rates of check valves, the tension on the ball that is covering the orifice doesn't always matter. If your looking for LPM leak rates then anything that closes the orifice would suffice, and the failure would come from the strength of the material used to make the body of the valve or how it is installed. If your looking for sccm or lower rates then the surface between the body and ball will matter more or if your looking for a zero leak rate an o-ring will be used. Also nearly all check valves have a "cracking pressure" which is the pressure needed for liquid or gas to move in the flow direction. So 3d printing a one piece check valve would become infinitely harder to make on a manufacturing level because you would most likely need a unique design for each different valve spec to compensate for unavoidable material properties.

What a smart way to do a portfolio submission/resume ;) I hope this video reaches the right eyes for your professional life.

Very very cool. Thanks for the awesome content!

You should look at extrude honing the surface internally. That would likely smooth the sealing surfaces substantially. Extrude hone is basically silly putty with grit of varying sizes to sand the surface as it flows through the orifice

I think the most important isn't the valve. It's a way to remove metal printed supports inside of a print without mechanical access. I will think about how many new possibilities are possible with that.

What a wonderful start

I do wish we could have seen a machined cross section of one of the valves which had the supports successfully removed with acid! I also would have enjoyed a more thorough explanation of why the stresses build up in such a way that the cantilever flexes up to close the valve (as opposed to wanting to flex away from the closed position or any other direction). Great work, though! Excited to see more projects.

One of the best engineering videos that I've seen

With the internal floating check valve, you could make the floating component with support from the centerpoint through the neck of the exit port of the valve (in the opposite direction of fluid flow) and print with that end down. Then, in removal of the support you simply cut the support flush with the valve channel end.

Very Cool. Your work gives me hope for the future of manufacturing globally distributed.

Krasses Video. Mach weiter so!

Great info! Thanks for the video.

that bit about the slm bubbles being flattened by the pressure was really interesting, maybe that can be integrated as a post print process for many parts to make them better

Brilliant video

I think you can get past the cooling limitation by using a laser to scan the print surface from time to time, and have it wait until the part has cooled down before continuing with the next layer. Maybe also use an AC unit to cool down the air inside the chamber very low temperatures, while also dehumidifying it, to help the part cool faster, and a constant flow of air towards the cooling surface, which to be slow enough to not disturb the powder but cold enough to help it cool faster, would do just that.

Interesting and funny as always!

The Tesla valve Isn't a check valve its a one way restriction valve. it restricts the airflow in one direction and not in the other. A check valve completely closes off and seals air/fluid from going in one direction and not in the other. Tesla valves although cool are nearly useless. they are used in very few applications.

@unitrader403

i think the purpose of Tesla valves was to restrict alternatg Flow with a very high frequency, something with moving parts cannot do since it has a delay because something has to move. Disadvntage of them is of course that they cannt shut off the flow completely, but if you care more about delay than about leakage thats a wothy tradeoff

Awesome work as always. I wish my school had a printer like that.

You did a very good job at explaining the metal printing working, thank you for that.👍👍 HOWEVER you also showed it makes economically no sense to make parts this way because you can't have (a good) production control on any of the inner (valve) parts. AND ofcourse because it takes forever and a few years to produce a part. Production speed(aka costs) and production(quality) control are the most deciding topics of any production process. It reminds me of the 5/2, 3/2 solenoid/air valves (WITHOUT mechanical valves) in which the airspeed was decisive for the working instead of mechanical valves. This was "future technology" many years ago but you never see them anymore for obvious reasons.

This is incredible.

I really enjoyed your video. I design and manufacture valves for rockets/in-space systems. The leakage requirements are very tight, usually 1E-3 SCCS at MEOP using helium. This basically forces you to have 8 Ra seal surfaces and soft goods like Teflon/Vespel/KEL-F. This is essentially what kills ability to use 3D printed designs. 3D printing also comes with two major downsides. 1) you are constantly printing dogbone samples for tensile testing since every print has to be validated and tested. 2) the surface finish on even non-critical parts of the print is very rough, to the point where it’s basically a foreign object debris (FOD) magnet, which FOD is one of the most common things we worry about with valves since it can easily force a valve open or closed or damage a seat seal where it stops sealing. I think this tech could have some benefit in systems that can have high leakage and are still weight sensitive. Maybe more on the engine side of aerospace potentially. But generally speaking, it’s easier to test individual valve units and then integrate them onto a product so that if it fails and needs to be replace that it can be replaced easily. Anyways, just wanted to share. Thanks for the video!

Great idea! Hope u get a cool project for u!

This is amazing!!!

Funny thing is, I just wondered two weeks ago, why you didn't upload stuff anymore. Nice to have you back :)

Definitely very neat. For in-situ valve lapping, the first thing that comes to mind for me is extrude-honing, A paste loaded with abrasive is flowed though a system, and cutting action heavier low-cross-section/ high linear velocity areas, and can greatly improve surface finish in the areas that need it most. Alternatively Since your check valve is a mass on a spring, put it on a shaker table and run it at resonance. Could repeated impacts make for the bumps and imperfection on the surface getting peened flat, or at least mated to each other?

WOW What timing for me!! I have been trying to design and print a Shuttle check valve and It's boggling my mind. I want liquid to flow in one direction unimpeded, but when it attempts to flow in the opposite direction, it isn't just stopped-- but ejected out of a third port unimpeded! Obviously when the flow returns from the first direction, the third port is sealed off from the flow. I believe this is called a shuttle check valve. or really a "quick exhaust valve" which you can google to see some diagrams. The bat-wing design may work for me. I aim to use this for an ebb flow system-- to prevent water from backflowing through the pump but instead redirecting it using gravity to flow into the reservoir. I am fine making this valve in FDM plastic because the application would not suffer from tiny/seeping leaks. I would like to use the rubber/silicone hose itself as the sealing surfaces inside the valve -- which I have done with success in a regular check-valve design. (The "ball" to seal was a cone shape and 3d printed in plastic). I am hoping to come up with a design that uses these same features for a quick exhaust valve. I would love if you or anyone else had any input!!! For it to work, I need to make it either print-in-place (preferred but harder), or screw together.. so I can print pieces separately and still maintain the valve in the future.

Sounds like a fun project, have you tried replacing the sealing ball with a double headed plunger? should seal and move a lot better than if you 3d-print a ball

WOOOOW it's really nice to see you again, de ami még jobban meglepett, hogy beszélsz magyarul :D

The company i work for makes various valves including check valves for the space launch companies. We have done some experimenting with 3d printing (although not specifically with check valves). We've always run into the issue with the surface finishes. At cryogenic temperatures you need a really fine finish. Usually a 4 or an 8. Especially since at those temperatures your either going to be using a metal on metal seal like yours or some form of cryogenic polymer like ptfe, pctfe or vespel. I'm sure at some point someone will solve that issue. For now, even in 3d printed rocket engines the valves are generally totally machined or printed and then machined.

Great Video

Nice video with novel designs and processes. I'll have to try out your FDM print in place check valve, as I've designed and printed low pressure checks in an emergency before, but they required either two part designs or a paused print to insert the check ball as mentioned.
