What excites me most about the technology is the creative freedom that is newly brought to the consumer. For only a few hundred dollars you can by an entry level 3D printer and open up a world of possibility of creating that was unimaginable only a few years ago. As an engineer this technology truly allows your visions to come to life. All you have to do is create a model on a software such as CAD and upload it to a 3D printer to have an instant prototype in hours. As the technology grows and cheap 3D printers become more advanced we would not have to go buy most of the things we need. Instead of everything being mass-produced then sold in stores consumers would simply print it at home.
