To anyone who hasn't seen it demonstrated, 3-D printing sounds futuristic-like the meals that materialized in the Jetsons' oven at the touch of a keypad. But the technology is quite straightforward: It is a small evolutionary step from spraying toner on paper to putting down layers of something more substantial (such as plastic resin) until the layers add up to an object.

3D printing will lead to huge developments of society in the upcoming years. It will be allow nationwide price drops. Additionally, goods will be able to be produced locally, which will eliminate the price of shipping. This will allow the domestic jobs to be increased drastically. Not only will goods be cheeper, but they will also be more customizable.

I like this link because it explains how 3D printing can be applied in different branches such as medicine, technology, architecture and more.

it really explains about what 3D printing is and its not complicated

3D Systems CEO Avi Reichental says 3D printing is localizing and transforming the manufacturing industry, moving the technology into version 2.0. The 3D printing industry is entering version 2.0, which will transform and localize manufacturing.

Australian scientists have found a way to print large but extremely lightweight and flexible solar panels like money. World-leading scientists at the CSIRO said the A3-sized panels, which are created by laying a liquid photovoltaic ink onto thin, flexible plastic could soon mean everyone has the ability to print their own solar panels at home.

This article describes the processes that are connected with 3D printing and how the method works. Also, it begins to describe the effects that it will have on a global scale between countries.

This article mentions that while some people say that 3D printing saves on transportation, it costs a lot for the electricity to heat the materials. It focuses on metal 3D printing which requires a much higher base temperature for the material to melt.

3D printing has helped medical fields improve drastically. With a 3D printer, not only is money saved, but the manufacturing efficiency is increased. Both dental laboratories and the development of hearing aids have been made simpler with the help of 3D printing. Additionally, tissue engineering has been improved.

The money saved from 3D printing is one of the major impacts on society. 3D printing has recently been used in hospitals to save money. Hospitals are in need of cable tethers to prevent cables from being tangled; however, the total cost of buying these tethers can add up. Therefore to save money the hospital made the cable tethers with a 3D printer.

What we think of as 3D printing, says Joseph DeSimone, is really just 2D printing over and over ... slowly. Onstage at TED2015, he unveils a bold new technique - inspired, yes, by Terminator 2 - that's 25 to 100 times faster, and creates smooth, strong parts. Could it finally help to fulfill the tremendous promise of 3D printing?

Has strong opinions about how 3D printing would help education

This article contains an almost two hour lecture containing three separate parts that may offer copious amounts of valuable information for the project.

This article discusses a Michigan Tech study that found that 3D printing can use forty one percent less energy than conventional methods. Combining that with the relative cheapness of some 3D printers and the diagrams to make them, it may be a viable option for many items.
