3D printing economic questions and considerations
Definition
Three dimensional printing refers to a procedure that employs the formation of solid three dimensional objects that can take the form of any shape desired based on the designs of a digital model. In order to achieve a three dimensional print output, one is required to utilize the additive procedure that involves the use of successive material layers that are laid in arrangement such that different shapes are displayed. There have been considerations of three dimensional printing as technique of traditional machining that greatly relies on material removal through use of methods such as drilling and cutting which is part of the subtractive procedure. I) History of 3D printing technology

The historical development and context of 3D printing technology Three dimensional printing has existed for over thirty years, long before it was popularized. From the 1980s this technology utilized the inclusion of a layer fused in powdered material with the combination of a laser as well as dispersion of plastic that was melted through a nozzle system and resin that was photo-cursed. Nonetheless, three dimensional printers remained expense ice and where characterized as being sluggish with inefficiencies as the industry redeveloped at a slow pace during that era (Lanzetta & Sachs, 2003). The rapid popularization and growth of three dimensional printing begun only after the start of the twenty first century as several obstacles were broken which reduce the varied barriers that made the technology accessible and available to potential customers and users alike. Today accessing or purchasing a three dimensional printer is easy in addition to being utilized for varying purposes. The widespread possibilities of the private utilization of this technology have created a potential significance in changing the ways in which products are formulated and manufactured. Consequently there is a belief that the "explosive" popularity and rise of three dimensional printing in the workplace and home setting with continue to grow exponentially than two dimensional printing technologies ever was. II) The technology of 3D printing

This technology provides for additive manufacturing as opposed to traditional subtractive methods. The procedures involved in three dimensional printing involve minimal stages that bear resemblance to the traditional printing forms; it begins with development of the prototype using specialized software. Thereafter the model has to be adjusted to fit three dimensional setting such that it can be printed in three dimensions. The model building process can take duration of many hours to several days or even more that one week in some cases which is all dependant on the approach and complexities of the specific project (Gobry, 2011). Such procedure involve the application of sophisticated modeling technologies that present restrain in the use of three dimensional printing which has led to an increase in the number of specialized software programs that are readily available to the users or customers alike. Some of these software programs are simplified in use, such that it would not require the expertise of a designer or architect as the only people that can use them. As the model waits readily, a transformation occurs along its horizontal cross sections that need to be extremely thin. Such upcoming layers have a compounding effect on the entire structure of the model as they are arranged in a stack formation. The next stage involves the data being sent to the printer that performs an analysis where after it begins printing, three dimensional printers lay down layers in a successive manner in powdered layers or material in form of sheets as a way of constructing the model in a cross section series format (Ratto & Ree, 2012). 3D printing technology allows us to easily make our own weapons This process is...
