I love how the "you wouldn't download a car" thing became a universal meme about how heck yeah we would
Haha we’d all be car thieves if we could download cars. Terrible anti piracy campaign… because downloading a movie is exactly like stealing someone’s car
i had seen that when i was a kid, look how far we actually came, we can actually download a car now lol
@@Shooritespecially when they stole the song
It's because that analogy was always so fucking stupid. It tries to imply that merely downloading a copy of some piece of information is the same as physically stealing an object from another person's possession, which is obvious bullshit. Also, yeah, I'd download a car if I could.
Great work and “shamelessly” executed!
Thanks :D

@@TurboSunShine 🔴 Why Islam not other religion
1-islam gives logical and simple idea for God - he is A perfect God - he is not a man nor a son of man nor an Idol or a trinity nor limited nor created - he is totally unique and to him belongs all the good qualities
2-Islam accepts all messengers of God -- about 124 0000 and in Islam, we love all the prophet of God and we can’t deny any of them - while in other religions such as Judaism for example - they reject Jesus and Mohammed -- and in Christianity they reject Muhammad ... but in Islam, we accept all .
3-in Islam, there is no mediator between you and God -- you can pray to God directly - there is no need for someone in between...
4- Islam is the Only religion that is Not named after a person or a tribe or a group, its name means submission to the One True God, if anyone anywhere at any time lived the life of submission to the true God alone , then he is a Muslim.
5- In Islam (worship) is not about mere rituals. it's a comprehensive term that includes any deed that pleases God. All good deeds are types of worship, smiling, being sincere at work, saying a nice word, and even treating one's spouse gently, all this is greatly rewarded by God. And in the opposite any deed that doesn't please God is a sin; talking bad about people is a sin, cheating, lying, hurting innocent people, harming the environment.
6-in Islam God is always forgiving - if you always repent (before death ) he will just accept you no matter how great sins you did >he forgive us out of his own grace - there is no price to be paid in order for him to forgive > so it's not like Christianity which says that God can't forgive except by blood of Jesus ..
7-Islam is a way of life - it organises each aspect in your life.. it has solutions and divine guidelines to problems in your life .
8--the sources of Islam also was collected and saved is also amazing -- it never happen to any book in history --- it's through the uncut chain of known narrators which date to prophet time ... besides the millions who memorised it from cover to cover since that time up till today - besides being documented in front of the prophet by known companions!
9-Islam prohibits blind following without knowledge and it invite us to use our brains to know truth, it is based on evidence and logic. The rational mind is the basis for religious accountability and responsibility.
10-the moral system of Islam is v high and perfect and thus the countries that apply Islamic laws in a proper way -- they have less moral crimes.
11-You won't lose Jesus if you accept Islam, but you will just correct your belief in him , In Islam, Jesus stands a good position in Islam as one of the messengers of God together with other messengers.. they were all special and they were all humans like us-- none of them must be worshiped -- we only worship God who sent them . we believe that Jesus was a noble Messenger of God but not divine,,,, we love Jesus and obey his true teachings and pray like him , fast like him , and a person won't lose Jesus if he accepts Islam -- but you will just correct his belief about him
12- Paradise in Islam is a real physical life for both Body and soul, you will go there , eating drinking marrying and meeting with prophets and having wonderful eternally unlike in other religions which they think its only spiritual life.
👉IN ISLAM THERE IS A PURE & CLEAR CONCEPTS OF GOD
🍃🍃🍃🍃🍃🍃🍃🍃
God is One and Unique: God has no partners, no equals and no rivals. God has no father, mother, sons, daughters or wives. God alone is worthy of all worship. God is the All-Powerful: God has full authority and power over all things. Obedience to God does not increase His Power, nor does disobedience decrease His power. God is the Most High: There is nothing above or comparable to God. The attributes of God do not resemble that of His creation. No part of God is present in anyone or anything. God is Perfect: God does not have any human limitations, such as resting on the seventh day after He created the universe.

That’s very intriguing, considering a portion of existing hydraulic systems are already designed with minimal bypass rather than leak tight valving I could see this being ready to use in some designs. Very interested in seeing more on the overpressure deformation sealing if you conduct more testing.
As a mechanical engineer when I came across 3d printing my first thought was that a new paradigm was needed. This is one of the first I have seen. Well done sir, well done.
I’m so happy that you are still doing this sort of stuff. After discovering your channel and finding out you haven’t uploaded for months or produced 3D printable models, I thought you were not going to do anymore. Honestly your models and video quality are UNDERRATED.
Edit: WOAH, Thank You for the likes!
COMPLETELY agree! I'm mad at CZcams for waiting so long to show me this channel!
Can't help but be worried that if you get picked up we'll never hear from you again. But Hey, even if that happens, you're brilliant and you absolutely deserve it.
nahhh, i usually come back ;)
@@TurboSunShine do they give you free candy or 11mm sockets?
I love how he just throws in his resume in the video. What a boss move. If I was in the position I would of considered hiring him.
So instead of an interrupted print, you have a psudeochaotic chemical process, and still needing multiple machining operations lol.
I dig your process, and artifical constraints help to further your methods, even if they aren't the greatest. You can see the issue with the porosoty of the sintered parts.
That prestressed bit with just a single drilling opertation is pretty sweet however!
Fantastic man... just super impressive, as always. Wish I had need for your services but think you are light-years ahead of anything I'm involved in. All the same, will print about anything you design, for the pure joy and awesomeness of your designs. Thank you for all your hard work and effort!
Thank goodness! I just found your stuff a couple months ago and couldn't find any new status from you in over a year or more anywhere. Glad you're back.
Great designs and awesome research. I really hope companies invest in you improving lots of their components 👏🏻👏🏻👏🏻
BRILLIANT! Great job putting this valve video together! Please keep the videos coming, you really do fantastic work with your designs, commentary, etc!
This is freaking awesome! I ought to convince my company to buy one of those printers though sadly I doubt they will be swayed that easily ;)
Haha, good luck, just don't tell them about the running costs👍
Hey, welcome back. Glad to see you doing well. Thanks for another thought-provoking video.
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.
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.
you're a genius man. i havent been mind blown like this from a video in a while
This has to be the best way to show your work experience and put your cv out in the job market.
I really enjoyed this with my kids.
Having reached the very technical deepness of youtube. I am amazingly satisfied for having found you in my recommendation. Thank you for being you and hope that you will have plenty of job coming with your skills.
This is fantastic. I run an M100 at work but we are very secretive and so are our competitors. To see such great details about LBPF metal on youtube is fantastic. Keep up the good work!
Great work man! Would love seeing such informative and practical videos in future.
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.
Many good points! And definitely the way to go if you want to do this today.
Yeah, I posted the same idea before reading your comment, a drill will work perfectly and way easier.
Simply amazing design, I really enjoyed watching the process.
11 days after you start uploading again, I find your channel, after months of craving someone who utilizes the properties of 3d printers to engineer genius designs. Pretty good day! Keep it up man!
how serendipitous! I was looking for decent check valves for a ram pump design for my garden! Thank you!
I'm probably overlooking something but particularly for the cantilever valve, could you not just drill out the supports from the outlet side?
in this case yes!, however if you print this inside of a larger and more complex system, then you will probably not have the possibility to do so.
I had a similar thought about this as well. In a simple valve you could just have the supports attached to a surface made to be cut out. However, he just explained why his design really shines.
@Sunshine but isn't removing it via chemical reaction or mechanical or by abrasive (if we would create some kind of relive hole so abrasive with water would be able to remove supports) wouldn't also be considered cheateting like with pausing print(as we still adding manufacturing operation there and pausing gives us chance to give some kind of oring or something like that) i think in this case pausing would give us more possibilities
If you make the supports look like this
@@otherwayup Although then you would need to design a path that would let you pass water all the way through your support structure with enough space left over afterwards for all of those supports to flex free
I've helped design, cast and forge different valves and your designs are incredible. I believe 3D printing and casting will meld together into an incredible manufacturing industry soon, especially with pumps and valves. Currently 3D printing is in specialized sections with high costs, but its changing rapidly to make designs that can cost less, made faster, and are sometimes stronger.
This was so cool. Great job!
I thought you were never going to upload again this is so cool. I can’t wait to see what will you do next
Good luck with new projects!!!
Glad to see your new designs!
Glad to see your videos again, this is neat.
Man you're so cool, I hope you really go places!
genius at work here
insane work man
Great work! I hope this video blows up
I love it! keep up the awesome work
Really good video man, i hope to see more as i enjoy this style of content
Awesome job sunshine.
Very cool, that self-limiting chemical etching scheme was very clever. Thanks for sharing!
Thanks! You probably already know what type of microscope i used at the end :p love your videos btw!
@@TurboSunShine Oh yeah, I immediately let out an "oooooh!" when I saw it, what a nice instrument! Definitely jealous! The models with A/B rotation axis are super cool too, being able to do a complete 3D scan at that level of detail is just bananas.
Great content, ultra high quality mic just lets me hear mouth spit even better!
I look forward to seeing future developments!!
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.
wow, this is just so super cool! Ser gjerne mer om metall 3D printing!
What an awesome project!!
This is the best CV I've seen in my whole life.
The world needs more folks like this.
Very interesting and well put together video, thanks.
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
Excellent video and explanation 👍
Érdekesnek ígérkezik. Ment is a feliratkozás! Talán még fel sem fogtuk igazán, milyen lehetőségek rejlenek a 3D nyomtatásban.
Sok sikert!
The legend is back!
This is really cool. Awesome work. Additive manufacturing is going to give us some amazing solutions in the future. 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.
Came by your channel 😀 Thank you for your content! immediately subscribed
I hope to use your consulting one day. Love what you do TY!
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.
lol i just watched a 15 minutes add without noticing until the end. well done, awesome and outstanding self promotion! 👏 btw your work is impressive!
Subscribed. This is amazing.
This one way valve by itself is just a really cool experiment. This and other innovations like it may come together and really help revolutionize the manufacturing process for our lowly vehicles and industrial processes as well as lofty rockets building our future that I do hope is a long and productive one.
Fascinating, subscribed 😁
coool! I just came across your channel and subscribed. I'm an aerospace engineer, and the industry is more and more getting hyped for 3D printed rocket engines. I work on valves. So far I haven't 3D printed any valves but it's just a matter of time.
This is one of the best videos I have seen on the internet so far, I really loved it.
I think it will be more interesting if you made a 3D printable Liquid piston rotary motor with all of it's pumps and stuff in the smallest form possible.
You can even make a DIY car out of it.
Please keep that awesome work ♥️
That was a great video! Definitely a new subscriber.
It looked like you could drill out the supports. It's machining but still a single 3d printed piece.
Cool video and great explanation! I would love to get into 3d printing again but we live full time in an rv. Great place for using 3d prints but not for 3d printing itself.
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.
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
"Tesla valves although cool are nearly useless"
for _what_ ?
unqualified "useless" is plain wrong
Using the internal stresses to seal the opening is genius. 👍
this was so crazy cool. im blown away
Very well done 😁
That's cool, really really cool!
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.
Using a drill to spin and mate the check valve plunger and case - clever!
Very interesting. Thanks for sharing your research.
I am so glad I fouyyour channel!!!
Amazing contact, exploring application for new tech :)
Did you test the FDM pressure limits ?
Nope. Probably a few bars, but would not want to put it under too much pressure.
Keep up the good work!
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.
