I personally have used a 3-D printer before, and I for one would use it again considering it was  a pretty mind blowing experience. The fact that I could give an input as to what I wish to come out, even if not the same exact dimensions as my input, and get an output that is proportionate to the T just astounds me. On top of that, the productivity of a 3-D printer is immense. If one were to need something that they did not have enough of, for example if someone needed a new toothbrush or something such as a new plate if one were to break then the printer would help out in great convenience. There are greater examples, but I wanted to stick to more common day uses for it to try to sell the idea that the 3-D printer can serve a great purpose for the every day user. With that said this creation of a 3-D printer just like everything else comes with great responsibility. Considering years to come with advances this comes with the upholding of using it for greater purposes and not illegal matters. The fact that something like this has been created still keeps me in awe and anxious to see what future inventions are to come because this is something that was only dreamed of when I was younger. This invention is amazing and I would definitely use it again.
