I guess anything is possible but I work on ventilators and I just can't imagine building one from scratch.

Well, that's embarrassing.

Interesting. Definitely apples and oranges. One is a Ferrari and one is a plywood skateboard.

I have no idea if it would work, but I thought it was interesting as well. I also found this from 10 years ago...

I wonder if it ever got developed.

I love your vision to help!
Yea, you're the guys I'm thinking bad things about, I'm a farmer and a real do-it-yourselfer with a lot of old stuff that needs worked on or at the least can't be left alone. If I build a ventilator there will be baling wire involved.

I'll tell you the same as I tell everybody else: engineers don't design products, accounts do. You wanna file complaints? So do we...

That said, nobody ever said I was good at it (and certainly not good at filming it), but I'm a DIY guy too... and I've used, and will use, bailing wire again.

I like that design. It could certainly save lives. There just aren't enough ventilators in the US and the ones we have are already being used at about 95% during flu season.

Not knowing what you know about them, and knowing I know nothing about them, I see a machine with probably under 1,000 critical (*mechanical anyhow) parts, with patent drawings on file that I can pull from, and I can turn that into CAD models that I can print/machine in probably a few days (or maybe a few weeks, depending) into a first prototype and then prep for full "production" runs. I'm not claiming to be the smart guy that knows how it works, but I'm absolutely the guy that can produce 3D parts of its parts, and if push came to shove, that's all we really need. Nobody cares what's in the sausage if it tastes good and I'm confident I can run the grinder.

But... Kinda proving my point, you're a guy that knows how they work, I'm a guy that can get the pieces made, and I'm pretty sure that together we could probably bolt one up. So, mission accomplished. INGO has an emergency ventilator manufacturing team in the blink of an eye.

Will they be of medical grade? Of course not! Will they probably work? Yep.

I get what you are saying. Honestly, if it would save lives I would be there to help. But, it sure wouldn't be easy.

It sure didn't take long for you to go from 6 or 8 a day to one in a few weeks, and blame the accountants. If I didn't know any better I'd think maybe you used that line before. But I'm in, if you guys want to meet in the middle you can use my shop.

Ventilator? Easy-Peasy.

Bunch of amateurs....
Just have the 3D printer whip one out.


































Ta-Da

Dead Duck I tried to rep you but INGO won't let me.

I'm sure availability is zero right now but I found a medical grade portable ventilator for just over 500 bucks. Not a Ferrari more like a VW bug but not bad.

You caught me, and I admit it, getting ahead of myself. That's one of my favorite things to do in all my pursuits...

in my mind I had envisioned the development running concurrent with my Mom's makeshift ER filling up, but, yes, you got me. The first one in a few weeks, then I stand by my statement of 6-8 a day with the tools I have at my disposal. If you're actually throwing the gauntlet down and the country is depending on it, I would actually venture I could get the prototyping time down to under a week. I know enough guys that are smarter than I am to get it done in that time frame if lives were hanging in the balance and we had to do it or everybody dies. Really, if it were that stark, I hope the entire manufacturing community would rally around it and we do it in a day or two.

As far as blaming accountants, there's nothing you're going to do to make me back off of that. I've often said that if engineers had our way we'd design you things that would last for generations. They'd also cost 10x more than you're accustomed, require at least that much more power to use, and have absolutely no safety or creature comforts because those almost always sacrifice the machine (i.e., your car would be better without you in it). When I've used that example in the past, it's usually in response to people who complain about "design obsolescence". No such course is offered in engineering school. That happens on the job and we're not the ones steering that boat. In the exact case of my tractor, I worked with guys who entered the trade when it was designed, at the same company that made it, and they had that same complaints that I do. So if you liked it better in the old days, we did too.

If you want to talk more about what it really means to be a design engineer (and the soul crushing from our employers that come with that career), we can start another thread if you want. I know there are a few engineers here and probably 10x as many angry guys that are the casualties of modern manufacturing and I promise you that none of us are "in on it". Blame the cost reduction, because that's where the blame belongs.

Spot on—repped.

I have a seat of SolidWorks and two Arduino Leonardos in my desk drawer. I don’t know crap about the Arduinos (they were for another project that was plug and chug).

But I can reverse engineer stuff like a beast and get CAD files out for 3D printing. I also know of a design firm in Indianapolis that has about eight 3-D printers including SLS & STL that I might be able to get involved. I’m in with time on my hands if I can get a unit for myself. And I’m serious.

If only there was a way to show this, potentially, otherwise uninitiated crowd the insane power of a technology they might be unfamiliar with in terms they would understand, especially combined with actual metal working tools...

(Language warning right at the end...)

I see we have a few beasts here at INGO willing to swing nuts on the project if it came down to it. I will sleep soundly knowing that my assumptions about the resources in this community were correct.

In the meantime, I may work on the plywood contraption up thread. But let me know ASAP if we are doing this. If it becomes something we need time will not be on our side.
