First are the many issues of protecting ones intellectual property and the risks of copyright. There are also challenges with the possibility of a 3D printed car causing an accident. Who will regulate the manufacturing? How will insurance companies deal with it? In the forefront of news is the production of unregistered weapons. l) Manufacturing with 3D printing is now a fast-growing field, with the technology becoming more accessible and affordable. Some think that it will revolutionize all kinds of manufacturing. While it offers some advantages, the process can be energy intensive and wasteful of material. The kind of object being produced can make a huge difference in the amount material used. An object with a great deal of hollow space will be easier to produce by 3D printing rather than milling (Proefrok, 2013). Making the items on a basic 3D printer took 41 to 64 percent less energy than making them in a factory and shipping them to the U.S., the study found (Kurzweil All Network, 2013). We will discuss the three Environmental factors to consider when 3D printing. They are the ability to localize production, eliminating the need for transporting prototypes and goods (EnvisionTEC, 2013). 5) SUBJECT ONE – 3D Printing Technology and History m) Brief description and the science behind it n) Historical development o) Assigned to Colette Davis p) Assisted by Kimberly Brooks 6) SUBJECT TWO – Medical and Military Use
