Is there any limits to what it can make? Is it illegal to make certain things out of the 3D printer? If so,tell me. How much money is a 3D printer?If I put a puppy in the scanner, would it be able to replicate the puppy? How does the 3-D printer know if something should move or not?
Answer
Let me answer your questions one at a time:
1. Is there any limits to what it can make?
Right now, yes. In the future, no. The technology today is not advanced enough to make anything. The most common materials used now are plastic, resin, and recently the technology has grown to include metal. Food (lots of chocolate) has recently been printed as have organic materials such as stem cells. However, right now the biggest constraints of 3D printing is size. Soon one can conceivably print things as big as buildings, but for now most printers are relatively small (12in.X12in. though there are some much larger commercial printers). The future of 3D printing will also allow for printing on a molecular level, but for now the technology can only print in the micro scale.
2. Strictly speaking there are no laws against printing anything in 3D. However, laws exist that prohibit the manufacturing of certain goods and these apply to things that a 3D printer can conceivably make. An example of something that is illegal to print in the U.S. is a full gun. One can print parts of a gun legally, but cannot print a whole gun.
3. The cost of a 3D printer varies greatly. One can buy a 3D printer for the home for as little as $499. Commercial 3D printers cost much more and can run upwards of $30,000. With the continual advancement of the technology you can expect to see the prices drop as time goes on.
4. If you scan a puppy in 3D, a printer can print it in 3D. It would most likely be made out of plastic or resin though, not nice soft puppy fur.
5. 3D printers can print moving parts. When an item is programed into the software it maps out exactly where to lay down material. Because 3D printing is additive manufacturing it doesn't print the parts one by one, but instead prints the whole object layer by successive layer. If the programing is correct then moving parts can be included in the printed final product.

What animal has the strongest bite in the world?
John W
They said on Dirty Jobs that the alligator turtle has the 2nd strongest bite in the world, but what has the strongest bite?
Ali gators and Crocodiles have a very strong bite, so do Hippos. But is it one of those animals or is there something with a stronger bite?
Answer
GREAT white sharks really do have the meanest jaws on the planet, say experts.
The fierce ocean predators have a bite force of about 1.8 tonnes - that's 20 times more powerful than humans.
Even a large African lion, with a bite force of 560g, can't compare with the shark's massive mouth.
Scientists used the latest X-ray and scanner technology for their research.
The team at the University of New South Wales made 3D models of the skull of an 8ft male great white using images from a CT scanner.
They digitally "crash tested" their computer model to simulate different scenarios and reveal the powerful bite of the fearsome predator.
The experts also worked out the complex distributions of stresses and strains that these forces impose on the shark's jaws.
But even the great white seems small fry when compared with the carcharodon megalodon. Dubbed Big Tooth, it was a prehistoric shark that was 53ft long and had a bite of around 18 tonnes.
It hunted large whales by biting off their tail and flippers before feeding at will.
By comparison, T-Rex could only manage a bite force of around 3.1 tonnes.
Steve Wroe, the study's lead author, said: "Pound for pound, the great white's bite is not particularly impressive but the sheer size of the animal means that it tops the scales.
"It must also be remembered that its extremely sharp serrated teeth require relatively little force to drive them through thick skin, fat and muscle.
"Nature has endowed this carnivore with more than enough bite force to kill and eat large and potentially dangerous prey."
Great whites can grow to about 20 feet in length and live for 30-40 years.
Hope it helps you!
