Dream Big

In the 21th century, human beings have witnessed the rapid improvement of technology. 3D printer is a desktop device that can print out an actual thing, such as entire cars, shoes and even blood vessels, and the price of this device is getting less costly nowadays.（3D printing is an emergent technology that allows personalized and customized manufacturing of real 3D objects. So in the same way that desktop publishing allows the individual to print books( rather thatn going to a publishing house)）However, the advanced technology has carried out some knotty problems. Intelligent criminals have found dark function of 3D printing, for instance, printing an unregistered AR-15 rifle part by part. In addition, there seems to a trend that, among the society, the employment position for manufacturer will be fewer. As far as I am concerned, 3D printing will bring about unimaginable changes and numerous benefits to society. I believe that the development of 3D printing will bring increasingly benefit to the society, changing the world for the better.

First, one of thee obvious benefit of 3D printing is allowing manufacturers to produce customized products at a lower cost. (For most industries, it would be a tempting opportunity to reduce the production costs.) Though the initial setup costs are relatively higher, the profit in the long term will be definitely maximized. For one thing, 3D printing has become cheaper than cheap labour in third world countries. Additionally, the cost of 3D printer will decline throughout the time, with the device being popular in the near future. Furthermore, the prototype is able to be quickly printed. Hence(consequently/thus/as a consequence), template can be easily modified if not satisfied. And the costs of customized products are the same for the mass production products, which means that the entity will get handsome profit from customized products.

Furthermore(moreover/ secondly), there are huge potential business opportunities in
