Saw this in a trade paper I get and had to laugh. Apparently the DHS is upset that the world won't cooperate and follow their regulations!
Once somebody figures out how to ceramic coat the inside of the barrel to handle the heat and erosion it should get even better.

DHS is why people think an all plastic gun is needed.

i just think its cool, not very practical(at this time, might be in the future) I think its a very cool tech that is going to change how alot of things are done.

The cartridges it fires are still made of metal. Brass, copper, lead and steel will all show up on a metal detector. People need to unclench.

I heard NASA is working on a Pizza 3D printer..the pizza is just an easy first try because of it's shape.. But it seems it will run from bottles of nutrients that have an extremely long shelf life, even after installed in the printer. So it might be cost savings..no waste or spoilage. No word on if the product will support human life yet....
And a lot of variety might be possible for a journey to, say, Mars or beyond.

Lets just call it what it is, a "replicater" . ;D
Here's the thing though, it's "multi media".
You use plastics and make a gun or wrench, use nutrients and print a pizza , where is this going ?
Put in some DNA and print someone a new heart or kidney ?
How about building a really big one to print a ship, or plane ?
One question about the material, after a project can you take the material that did not become part and reuse it ?

Recently they printed a throat for a kid and it saved his life. the applcantions for being able to print a object are endless.

They've been doing that with joints for a while out of Titanium alloy IIRC.

Tom, the answer to your question should be yes. I'm sure there are some limitations if the residue contains multiple components, however.
Your question was a good one, as the materials can be quite expensive.
-
If the printers got down to where they could create stuff at the molecular level...print working internals of molecules, they might be getting close to working organs.
I think Nanotechnology would get there first.
If I had stacks of cash to invest and 20 years to wait, I'd be looking hard at Nanotech companies.

THey will have parts cloning pretty soon, they already do for some things.

You can order manufactured DNA today for a price. Used to be researchers had to mutate a cell to get it to express the new DNA you wanted (this is still the main way it is done using e coli). Now there is at least one place where you send them your code and they print it up from the four subunits and send it to you.
There are folks working on manufacturing organs but it is still pretty early. One of the hot goals is to make skin for burns and scar replacement. People have been dreaming of ways to make fake skin for decades. It is very hard to replicate just like membranes for fuel cells. My first job out of college in 1981 was in R & D where about half the folks were working on what they called microporous separators AKA membranes. After many years and much $ they shut it down. 30 years later we are a little closer to success but not all that much. My bet is that someone will take some nanotech tools and some biotech tools add in some hard work and genius and hit the jackpot.

Very interesting post Joe, but my money is on the "vulcanization/ Kevlar" approach .
Some one will spill something on something else and as they try to clean up the mess they will start saying "WTF ? " and get a Nobel prize in Medicine . ;D
http://en.wikipedia.org/wiki/Kevlar
Poly-paraphenylene terephthalamide – branded Kevlar – was invented by Polish-American chemist Stephanie Kwolek while working for DuPont,[6] in anticipation of a gasoline shortage. In 1964, her group began searching for a new lightweight strong fiber to use for light but strong tires.[6] The polymers she had been working with at the time, poly-p-Phenylene-terephthalate and polybenzamide,[7] formed liquid crystal while in solution, something unique to those polymers at the time.[6]
The solution was "cloudy, opalescent upon being stirred, and of low viscosity" and usually was thrown away. However, Kwolek persuaded the technician, Charles Smullen, who ran the "spinneret", to test her solution, and was amazed to find that the fiber did not break, unlike nylon. Her supervisor and her laboratory director understood the significance of her accidental discovery and a new field of polymer chemistry quickly arose. By 1971, modern Kevlar was introduced.[6] However, Kwolek was not very involved in developing the applications of Kevlar.[8]

Other sources claim that Goodyear accidentally spilled the rubber mixture on a hot stove. The key discovery was that heating natural rubber and sulfur created vulcanized rubber. This process was eventually refined to become the vulcanizing process.

Hey, the glue on "sticky notes" was discovered while trying to come up with a super strong glue! Never know what you'll invent accidently.

Ahh, the wonders of working with your elbows .
Just goes to show you that even clumsy oafs have contributed more to American society than Obama's sacred Muslims.

Heard this story years ago and the point the guy made was that the inventor had the curiosity to ask "what could i do with a not so sticky glue?" Apparently when he made the first sticky notes to test in house the folks at 3M loved them and they fast tracked it to production. $$$
