Negatives And Negatives Of 3 D Printing

Good Essays

3-D printing, is an amazing new technology that has already started many debates about its validity and its possible positive and negative impacts in the future. I believe that 3-D printing technologies is going to have a major impact in our daily lives and the positive benefits is going to outweigh the negatives.

3-D printing is a process of making a three-dimensional solid object of virtually any shape from a digital model. It covers many different technologies that achieve similar effects, the major differences being the size of production and end product, affordability and product strength.

The first 3D printing technology invented by Charles Hull was called stereolithography. Which is printing in layers. This system consists of an …show more content…

The laser beam then traces the boundaries and fills in a two-dimensional cross section of the model, solidifying the resin wherever it touches. Once a layer is completed, the platform descends a layer thickness, resin flows over the first layer, and the next layer is built. This process continues until the model is completed. There is also process that uses extrusion tube that flows out melting plastics or other materials that will take shape in 3D object and a process where glue or laser fuse together metal in a similar process to the stereolithography where by the plastic is replace by metal grinds.

3-D printing is the start the new industrial revolution and will soon change the world. These devices will allow us to print three-dimensional objects at home, from phones cases, jewelry, ceramics and even food in the future.

This type of technology could make almost anything, including a gun? Cody R Wilson, a second year law student from The University of Texas School of Law di this and created an organization called Defense Distributed, which aims at designing a firearm that can be downloaded from the internet and printed with a 3D printer. On May 5th 2013, he achieved this goal. With the design of Liberator, a single shot pistol from the World War II era, he was able to fire a single round of bullet with a plastic gun with parts made from a 3D printer. Congressman Steve Israel, an activist for gun controls and against 3D printed weapons, issue
