3-D Printing

Just recently I have heard news on trying to make 3-d printing efficient. It has existed for over 20 years, but since it's so expensive, only industries do it. Many people who are trying to figure out what ways will be easiest to make this happen without affecting the economy, have thought about using recycled plastic and melting it for use of ink. I think that 3-D printing could change so much in the world. As a person who enjoys being artistic, I think that getting to witness 3-d printing would be amazing. It would also be helpful for movies and plays for making small props. I believe that the only problem that could possibly occur would be copyright...which could lead to a huge argument. I hope people will decide to try it!
