3D Printing
"There are no old roads to new directions" -The Boston Consulting Group
"The more original a discovery, the more obvious it seems afterwards".-Arthur Koestler
3D printing is making a three-demensional solid object of any shape from a digital model. 3D printing is made from using an additive process, where many different layers of material are put down in different shapes. 3D printing is considered distinct from traditional machines, which mostly rely on the taking away of material by use such as cutting or drilling. A material printer usually performs 3D printing using digital technology. Since the start of the twenty-first century there has been a large raise in the sales of these machines, and their price has dropped.
How It Works:
It all starts with making a virtual design of the object you want to create. This design is made in a CAD (Computer Aided Design) file using a 3D modeling program (for the creation of a totally new object) or with the use of a 3D scanner (to copy an existing object). This scanner makes a 3D copy of an object and puts it into the 3D program.
To prepare the digital file created in a 3D modeling program for printing, the software cuts up the final model into hundreds or thousands of layers. When this file is uploaded in the 3D printer, the printer creates the object layer by layer. The 3D printer reads every piece (or 2D image) and continues to create the object mixing each layer together with no evidence of the layering visible, resulting in one 3D object.
Predictions for future commercial additive manufacturing, starting with today's young period, require manufacturing firms to be flexible,ever-improving users of all available technologies in order to remain an important factor of manufacturing also predict that this arc of technological development will counter globalization as end users will do much of their own manufacturing rather than engage in trade to buy products from other people and corporations. The real integration of the newer additive technologies into commercial production, however, is more a matter of complementing traditional subjective methods rather then displaying the whole thing.

3D Printing in The Real World: In terms of schools, 3D printing is starting to be used across the county. it ius started to be used in more "technology based schools", or engineering schools. For example, North Carolina state University.
http://web.ncsu.edu/abstract/technology/3d-printing/ .Under graduates at North Carolina State university who are taking the course,
"Advanced Digital Product Modeling" were given the task to create the task to create the characters from transformers on 3D printers as a functional action figure. Another College that has started to use 3D printing in their courses is the East tennese Sate University.

Dangerous Effects:Although this new invention is great and can help the world a lot, it also can be used for bad. Some people have been making guns with 3D printers, and the guns actually shoot. If people have such easy grasp to getting a gun, it may cause some serious tension in our country.By just a click, any one who obtains this 3D printer can own their own assault riffle. As of now, there are no gun laws for 3D printers.If laws are not enforced soon, this ability to print guns may lead into a bigger country

Net Gen Norm(Innovation):
Imagine a world where you can print out any object you designed on the computer. Although this can be dangerous it can also help in warfare for fast production of weapons.This, or even just creating a cool object on your computer and being able to print it out and have it in your room. In future schools, this 3D printer may be able to print out binders, or school supplies. For artists, this printer may be able to print out paint brushes, or maybe even cameras.This dream has become a reality for many people

3D Printing in Schools:

In the future there will be alot of growing technolegy of the world. Something that has already been invented is the 3D printing systems. Having these printers in schools can lead to a lot of learning and growth of knowledge in the new generation. There are so many possible ideas that anyone can create from a 3D printer. Shoes and dresses can also be made from a 3D printer. What if a 15 year old created the next big shoe trend or idea from a 3D printer in schools. They are expensive, that may be a problem in numerous schools nationwide.
