Transcript of The 3D Printer

So That's How it Works.
But is there really any point to it? First impressions make it seem impractical, but as we all know, first impressions can be far from the truth.
How does it work?
What is 3D printing?

3D printing is a new method of printing invented by Chuck Hull, the chief technology officer of 3D Systems. Years ago he invented a method called stereolithography, or the process of printing 3D objects using a digital scale model.
As years progressed, stereolithography
grew, and 3D printing was born. Now the technology is much more advanced and the possibilities for printing are endless.
SO...
Mr. Chuck Hull
Like we mentioned before , stereolithography is the process of transferring 3D C.G.I. into real-life models.
But it seems impossible... in order to build solid-standing objects, they must be sturdy, and well planned out. Well, as long as the designer creates his object well, the printer will take care of the rest.
In order to "solidify" the 3D image, the printer must use materials specialized for 3D printing. These material functions as an equivalent to ink used in the conventional printer, and comes in several forms such as:
Plastic (ABS or PLA type)
Nylon
Epoxy
But!!!!
That's not all...! 3D printers can build with almost any material, if it can be ground down
into a fine powder substance. Meaning things such as rubber, metal, or even
gold
can be used in 3D printing.
Building From The Bottom Up
So... It all sounds possible, but how does it manage to
take a piece of coiled nylon or metal, and turn it into a
structure like this???

Divide and Conquer...
But Wait..! We Skipped a step!
It's Like a Spray-on Tan
...But Better...
In order for that strange tube of nylon
to be transformed into a beautiful paper weight for your office, the printer is going to have to start doing some work.
So here's what it does.
First, what the printer must do is prepare the platform in which it's building on.
Some printers work hand-in-hand with their platforms, meaning the platform moves as well as the arm. While others are solely the arm's work.
The arm is then fed the
material, (aka nylon, rubber, etc.) and prepares it to be sprayed. It then sprays the material onto the platform in the shape of the first layer of the possible thousands to come.
After the first layer is put down, laser technology is used to dry the spray and make it all stick together. Now the layer is sturdy, (or as sturdy as the material used to build it its,) and is ready for the next layer. The process is repeated over and over, and soon, the printing is all done.
The first few layers
of a 3D printed object.
The Printer at work.
A final product of the 3D printer.
3D printers are able to make real guitars that sound better than you might think!
They can make waterproof, breathable casts individually made for better comfort and support!
Also, 3D printers can now make cars!
Both for real-life, fully functional purposes,
...to Hollywood!
As well as other scientific advancements...
The most incredible implementation, however, is the possibility of printing houses.
3D printing is the way of the future
And the future is now!
So in order for the object to, well, exist, a computer must first receive the 3D template. Then after it has been transferred, the printer begins to "slice" the 3D design into hundreds of layers to be created by the printer. Once it has been "sliced", the fun part really comes into play...
As well as pan flutes!
