3-D printing sounds very futuristic and complicated, but it is actually just the process of putting down layers of a substance such as plastic until the layers add up to an object. They spray millions of droplets of polymer to build an object layer by layer until they have the finished product. I feel that 3-D printing is an important step towards a new era of more advanced technology. 3-D printing will soon have a large effect on society and even business because more goods will be able to be produced at their point of purchase or even be produced in one's own household. Products will also be more customized to what the consumer wants because it is easier to change the settings of a 3-D printer.
