Discusses what 3D printing is, the different types/methods of 3D printing, applications for 3D printing, and 3D printer vendors. A good place to get an understanding of 3D printing and a good place to look for specific areas of research.

Look at the sources the wiki article references that are listed at the bottom and suggestions for further reading to broaden your research set.

Thought this might be interesting if you haven't seen it yet. http://tek-bull.com/2012/02/scientists-created-a-machine-for-printing-houses-on-the-moon/

"Explaining The Future" is a site that explains technologies, current usage, and future potential. The site can be used for many technologies, trends, challenges, and thoughts/mindsets.

This is a great resource for you and your colleagues. Interesting and up to date!

This article has an introduction to 3D printing, history of rapid prototyping (3D printing), explanation of 3D printing, the current state of 3D printing, the future of 3D printing, and a Q&A with employees of 3D printing companies.

This site is a chart of 3D printers below $20,000. It shows the manufacturer, model, method, price, annual service cost, size & weight, build envelope, materials, material costs, speed, accuracy, finish of the final product, strengths, and weaknesses.

With this kind of detailed information, you may consider a slightly different kind of feasibility report which is context specific. For example you may consider the feasibility of ERAU's DB campus acquiring such an item? You could consider need/usability and cost.

Taken from "Technology Review," this article touches on how 3D printing has effect the toy industry. Very basic article, just shows some of the potentials of 3D printing. Taken from Technology Review: "what's changed since the invention of 3D scanners and stereolithography -- now known by the more inclusive term 3D printing -- is that they now have the ability to directly translate real world objects into miniature versions of themselves."

3D Systems is a company which sells 3D printers and 3D printer materials. This site has links to different 3D printers, ranging from personal to industrial. The site also has different materials that 3D Systems' printers use.
