I have printed small one time parts for a few things. Cheaper than ordering the replacement from the manufacture. I have also found the files and printed some good household items that are used daily.
It had a stupid design with a plastic trim ring that was decorative more than anything else. It wound up in a drawer until this week. Found a file to print a replacement plastic trim ring for this model flashlight..... And it's back in use.
If I could assess in a matter of hours if a part downloaded from the internet would work, I could skip point 2 and just focus on 1 and 3.
Here is an example of that put to use.
A plastic knob on my mother's mixer broke, the metal screw was fine. I found this, printed it, and fixed it for less than a dollar. I heated the screw, pushed it into the new knob, the plastic melted and snugly sealed around the metal screw. I see other people had the same problem.

The truly useful applications of 3D printing will appear when they can print at a molecular level, or at least multiple materials at a super fine pitch.
Until then ... injection molding machines operated by factory workers at $0.11 an hour in China are still a more viable option.
Apparently you think 3D printing can only be and should only be used for mass production.
They have 3D food printers, but that is more artsie-fartsie food fantasy. Of course soon all fast food will be made by machine.
Just the opposite, actually. 3-D printing is going to be great for *small* manufacturing runs. Custom designs for a single job where you only need half a dozen pieces are now practical.
Think about the processes currently used to manufacture circuit boards. I have an engineer friend who is regularly faced with the same choice for any particular board: fab it himself, or send it to China. Even at a small quantity, the 11 year old girl in China can fab the board cheaper than he can with his own tooling. But he has to wait for it. If he needs it "now" he gets out the materials and does it in his own shop.
Advanced 3-D printing will do the same for pieces and parts of any type.
As for machine-manufactured fast food ... that's a politics problem not an engineering problem.

Hopefully they won't be printers.
I want a REPLICATOR!
In search of a new buckling spring keyboard, I bought a Unicomp. It looks like an old IBM Model M keyboard - the greatest keyboard ever made, and if you don't agree, you're wrong - but the quality isn't really there. I'll use if, but I may wind up buying an Matias again. There's weird plastic flashing visible on some of the key caps. There are a few keys where the height isn't perfectly consistant. The blue LED's are too bright. There are some gaps where there really shouldn't be (the whole left side of the keyboard). But the classic feel is there. Too bad the sound isn't as good as the old Model M.
Anyway, if you like the keyboards of yesteryear, it's a reasonable facsimile.
And yes, the M is the best keyboard ever, but it's the best for people who TYPE. People who are hardcore gamers may be looking for different features, and frankly if all they do is pound on the keyboard like a game controller, they don't deserve an M. :)
Nothing but M for me. I've got two that are in good working order, one at home and one at work. When I have to type during a conference call I sometimes move my hands over to the laptop keyboard to make less noise.
I'm also giving some consideration to switching from a mouse to a trackball.
The "real computer users" community seems to like the Logitech M570. Dunno if anyone has had any experience with any other products.
I have tried the Slimblade one and decided its not for me. I don't like how the scrolling action works (rotating the ball rather than the dedicated scroll ring). Otherwise Kensington gets my vote.
My other trackball-loving friend swears by CST (Clearly Superior Technologies) which seems to be a favorite in some circles... here's one of theirs on Amazon: <http://www.amazon.com/gp/product/B00ECHGE3O/> and their website: <http://clearlysuperiortech.com>. I am sure they are technically better than the Kensingtons (higher DPI, etc) but they don't look like they'd be as ergonomic to use so I have never tried one.
I have wanted to try the Quiet Pro as I have heard it is better in this regard and closer to the AEK in its feel, but I haven't had a chance yet.
I've revived my Cherry G80-5000 using a soarer converter:
If you google around a bit around that, they also do a diy keyboard.
