3D printing might sound like something out of a science fiction comic. Now it’s a reality. The year is 2015 and the technologies nowadays have expanded. From laptops to cars, they have all been remodeled for the fast-pacing society. Now, the printing world has evolved more than we ever imagined! The 3D printer is probably one of the greatest inventions of society today. But of course, with every invention there are always some disadvantages. 3D printing is one of the greatest inventions anyone has ever made. 3D printers allow you to print any three dimensional object from your computer. Original printers work by putting ink on paper. 3D printers don’t work like that. They work with materials like metal, plastic, and ceramic. The printers put down these materials, thin layer after thin layer from the bottom to the top, to make the desired object. 3D printing has many advantages. 3D printers can help doctors, especially surgeons. The website http://www.philforhumanity.com/, states, “ Imagine doctors quickly building and replacing critical organs, such as the heart, lungs, or liver that will have almost no chance of donor rejection, since the organs will be built using the patients’ unique characters and DNA.” 3D printers can help save the lives of people by printing out human body parts like hearts and livers for operation such as heart transplants or liver transplants. This shows that 3D printers are one of the greatest inventions ever made because they have advantages which could save the lives of people. Another advantage of 3D printers is they can help create more jobs. With more jobs, that will help the economy. The website, http://www.philforhumanity.com/, states, “More engineers are needed to design and build 3D printers, and more technicians are needed to maintain, use, and fix 3D printers too. Additionally, with the lower cost of manufacturing, more designers and artists would be able deliver their products to the market. Even more...
