3D Printing!!!!

As technology advances so will the ways of people taking advantage of it. I agree with the 3D printing perspective, however it should only be used for medical or business reasons. You should not be able to buy a 3D for home use. It should be for creating limbs for a war veteran not for some designer shoes. If marketed for home use will it be cheap? In my opinion the manufacture would most likely sell it at a high price. Also this would hurt small business's that rely on the consumer coming in and buying these small items. Why would you leave your home if you could just create the product you want in your living room. What would stop a boy from printing a gun out and bringing it to school and doing harm? To sum this up, I am for it if it is going to help sick or injured members of society only and not for it the being able to print shoes.
