What is 3-D Printing?
As know for the generations of technology advancement. Three dimensional printing brings new a journey, and excitement to 3-D printing. 3-D printing brings advantages over manufacturing production, and also brings many challenges to manufacturing. Many challenges such as piracy, and property label issues add uncertainty of production. Advantages such as one-off production versus mass production, and additive, subtractive manufacturing to 3-D printing. Also, lower level of training required for production of mass complex objects, and the difference of diverse product bring excitement to this new advanced technology.
First, 3-D printing brings challenges, for instant piracy and property production right. While piracy is a concern, duplication of an item may not be possible because of its difficult level of skill. Once a file is formed into a computer it can easy be stolen. “ Once an object- the latest smart phone, for example-can be described in a digital file and played out onto a 3-D printer- it becomes much, much easier to steal.” (Johnston, 2011). Through digital management Software (DRM) by Apple it is able to sell digital file, which digitally cannot be transferred or copied to an Apple Inc consumers. In a short time file of all types that are currently secure, could possibly up on the internet. “ If its digital- It can be copied.” ( Johnston, 2011)
Secondly, 3-D printing is produced among the common way products are manufactured. The most common manufacturing is additive, and subtractive manufacturing. One modern method of manufacturing is subtractive method. Subtractive method begins with solid pieces of material, such material in which layers, and pieces are removed to arrive for the finished product.” Traditional approaches for creating objects remove material; they are subtractive.” (Ehrenberg, 2013). In the case of 3-D printing additive manufacturing is the preferred method. Additive manufacturing builds objects by piling up excessive layers to material, which in term becomes “Additive”. Printer in which are stationary head depositions material to a movable platform (Ehrenberg, 2013). 3-D material which deposit into layers by using plastic, resin, and metal that build up, making a 3-D object. Using additive over subtractive method of manufacturing is efficient due to waste management is kept to minimal. “ Conventional manufacturing- machining plastics excursions, etc- are used to create actual product. ( Johnston, 2011).”
Third advantages to 3-D printing is one manufacture ability to make one object instead of massed produced objects. By removing mass for manufacturing while making one limited item affordable. For example, small businesses produce, and manufactured minimal of their products to test it in the market. Essentially, by not having to buy out manufacturing company to produce that limited product in which may possible not sale.
Further more 3-D printing new designing requiring minimal training and skill level for design of a complex object. 3-D printing is a democratizing design in which enables new creative perspective. “ One way to create design tools for casual users based on natural user interfaces.” (Lipson, 2012). For example, Children are able to create toys based on their interest, and design of toys. As new 3-D design tools will be less complex then original tools, it will be completed without much manufacturing process.
Finally, 3-D is also being used for dental prototypes. “Creates a digital prototype of a mouth which can be used to design 3-D print” ( Johnston, 2011) . Enabling oral surgeons to practice safe and more accurate procedures. For example, using a 3-D model to better determine patients exact representation of their mouth, and jawbone. Secondly, 3-D technology used in medical implants such as hip,and spinal were performed.

For as 3-D printing future is uncertain, but holds a certainty for business and consumers. 3-D brings excitement to new technologies, but also a greater risk. 3-D technologies brought to manufacturing removing skills requirement, but also bringing a brighter future with challenges.
