    Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: simplisafe.com/veritasium
    I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:
    www.compliantmechanisms.byu.edu
    At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.
    What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:
    1. Part count (reduced by having flexible parts instead of springs, hinges)
    2. Productions processes (many, new, different enabled by compliant designs)
    3. Price (reduced by fewer parts and different production processes)
    4. Precise Motion (no backlash, less wear, friction)
    5. Performance (no outgassing, doesn't require lubricant)
    6. Proportions (reduced through different production processes)
    7. Portability (lightweight due to simpler, reduced part count designs)
    8. Predictability (devices are reliable over a long period of time)

"It's always been considered to be bad, to have flexibility in your mashine." I think that is a very misleading statement. There have always been parts of machines that have to be rigid, and parts that have to be flexible. Springs, "snapping latches" and other principles shown in this video, have been arround forever.

Mechanical systems can be much more reliable than electronic ones. I wouldn't be surprised if nuclear bombs have many mechanical devices in them. I heard of a missile that used a spring-wound gyroscope instead of motor driven. It didn't use a battery that could go bad or need to be replaced. It only needed to run for a minute or so, so using mechanical energy made since. It could be stored for years without worrying about replacing the battery.

+Krosis Depends on the system and what the requirements of it are. Some systems don't require a ton of structural strength - most power tools have nylon structural members and casing already. Plus, 3D printing is already possible with a ton of other materials as well (the video had pieces 3D printed with titanium and steel, for example). As for the flexibility of the tools themselves - they're only flexible in places that it needs to be flexible and only to the degree that it is necessary. We're not talking about weird gumby parts with no rigidity at all - they just flex in specific points. Look at the plastic vice grip he made. Normal vice grips are made out of steel and yet the same thing can be accomplished with PLA because the force is distributed differently thru the tool.

+XPOHOC Yeah, no kidding. I work at a hardware store that sells chainsaws and generators and you would not believe how many customers have to wait weeks to get a random plastic shroud or cover or a rubber gasket. And it's not cheap. The real question is if manufacturers are going to start embracing this technology or if they're going to go all recording industry and just engage in a massively futile effort that just delays the inevitable. There are parts that will still require traditional manufacturing (or at least 3D printing sophisticated enough that it doesn't make economic sense for service centers to have the 3D printer required) but a LOT of stuff could literally just be a quick file download and 3D print instead of spending 15 minutes putting in an order on a clunky website and then waiting weeks to get a piece of plastic or a 10 cent rubber ring.

Nah. The ones they showed were just single pieces. Like anything else you could build entire systems out of these pieces and just replace any broken parts like we already do with normal mechanical systems. Also replacements would be cheaper and easier to get - no more ordering parts and waiting for them to be delivered - just download the file (if you don't have it already) and 3D print it.

Its great to see people are starting to use flexibility as an advantage in designs (even though I personally never use it). My concern is that when using flexible materials in designs like the WMD activation device, you would have to really see how long thin pieces of whatever material they would use can last without input for years. From my experiences, when things are just sitting out, events in a temperature controlled room, they're going to degrade, plastics especially. I'm not trying to sound like an ass but that switch test is definitely flawed. Sure you can take a freshly molded/printed plastic switch and it works as he said over a million times without breaking, but that was also in an environmentally controlled room. I would like to see how well it works after going through heating and cold cycles, in different humid environments, and after just sitting for extended periods of time. If it can do all those better than traditional switches then you've got yourself a good design.

Mechanical fatigue due to repeated movement is one thing, heat cycle fatigue is another. Would like to see how it tested against conventional tools in a heat cycle environment, maybe the machine turns on and it got hot, and then turns off and cools again. Or rather cycle life in extreme temperature conditions. Very interesting video

Isn't this video kind of pointless? I mean, _of course_ machines that bend are better than machines that don't bend. It's a foregone conclusion - if I have a device that can do X, and another device that can do X + A, then the device that can do X + A wins every time. The only reason that wouldn't be so is because of cost considerations and that's not a factor here. Anyone with the functioning intelligence of a eighth grader should be able to understand this fairly readily without having to watch 13 minute long video on the matter... But then I suppose the creator wouldn't be able to keep raking in that sweet sweet ad revenue on Youtube, so there's that, I guess.
