Can someone answer my questions about the 3-D printer?




Joey


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!

How or where can I find a person or company with the ability to copy a sculpture with a CNC (or other) machine?




customarti


I am wanting to reproduce a classic sculpture that I have, in a larger size. I believe that I have seen machines on TV that can accurately measure and reproduce a sculpture without an artist having to actually chiesel it. I just cannot afford thousands to have it hand carved, and I am not very particular about fine quality so long as it is reasonable. Can anyone direct me please?


Answer
there are 3D scanners and various rapid prototyping machines, ranging from printers to CNC machines. Though large scale printers are much rarer than large scale CNC.

If you google rapid prototyping services you'll find some companies. But it's most likely going to be much more expensive than looking if you can locate a larger version of your sculpture, particularly if yours is a popular one. A large run reproduction will always be cheaper than an unique custom fabricated item.

What can I use to cast a mold from stone without hurting the stone?




disciple


I'm new to this, but does anyone know what medium I would use to make a mold from a stone. In other words, There is an old building with a beautiful design sculpted in to it. I want to copy this design. I know there is a material out there that I can press against the original design and make a mold of it and then cast the design in plaster. I just don't know what material I would use to do this without hurting the stone.... Help!!!


Answer
I think the sculpey or any clay will work. If you use normal clay, any residue left will dissolve in the next rain, just don't use brown clay on light stone... if you use water based clay you would have to cast your plaster into the mold while the clay is still wet.
As the clay won't be very stable just on its own, you should consider making a mother mold on top of that. That is a hard shell, which just gives support to the soft part of your mold so it doesn't deform. It depends on the size of what you want to copy if you need it. You could make the mothermold from plaster bandages, but don't put plaster directly on the stone.
Before you start, consider carefully the shape of what you want to copy and where undercuts are and where you have to put in parting lines. What technique you use for mold making really depends on the exact shape of what you want to copy. If the structure is something complicated, you may want to practice how to make molds from more simple structures first so you are aware what causes problems and get some experience in how to solve them.

Another completely contact free method is if you happen to be at a university where they have a 3D laser scanning camera you can borrow, you could use the 3D laser scanner then make a model of your structure in the computer from the scans. That you could print out using a 3D printer. that way you can scale the model to any size (though anything large will be expensive to print)
