Even though 3-D printer is a new piece of technology, many big schools like Harvard wrote an article about how this technology will change how we manufacture products. In my previous post, I wrote about capabilities of the 3-D printer. There are some similarities between two articles. Both of the article mentions that it will change how we manufacture and lower producing cost, and elimination of shipping and huge inventories. However, there are difference between two articles. In the last article, it is mentioning that 3-D printer can produce different products, but the article from Harvard mostly talks about the economic difference. Both of the article work together by how it can change the era of how we live.
