    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)

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.

"He's pretty nonchalant about his work." Just bragged about how his book is the most cited source in compliant mechanisms and over-exaggerated about how all engineers do nothing but design against flexion.

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.

The video "Legalize Democracy" here on Youtube (30 min) does a good job of explaining why this is step ONE to solving ALL of the major issues confronting the average people struggling to get by and have their voices heard in a corrupt political system.

There are a couple of different ways, but any metal that can be powdered can be printed. One way is that a thin layer of powder is laid down and a binder is sprayed on it very precisely where you want to build the part. Then additional layers are put down, each with the binder where you are building the part. Essentially you glue the powder together and the loose powder falls away and you have a somewhat fragile powder part. Then you sinter the part and the powder fuses together to become solid. Another way is that instead of a binder you melt the powder with a laser in consecutive thin layers and each layer bonds to the layer before it, building up a part. It didn't need to be sintered because it's already been melted together with the laser. You can also get metal filament for a traditional consumer FDM 3D printer, print a part and then melt out the plastic to have an all metal part.
