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 3D printing, for 3D printer can provide a wide variety of manufactured products, including customizable products and even personal designed products. For example, the author of the article writes that there are many potential things a “savvy 3D printer owner” can print. Things like “keys to your home, ofiice, cars, spare parts, entire cars and blood

vessels. Thus, a company can swiftly diversify and expand the variety of their products by taking the advantage of 3D printing, and thereby reducing the risk by overinvesting in one product. As a saying goes, “don’t put all your eggs in one basket. ” ??????? Moreover, one of the world-shaking innovation 3D printing create is the manufacturing of customizable human body parts or organs. For instance, in one of the most famous TED demonstration, a doctor printed out a kidney in 7 hours. Though the application is still experimental, the potential benefits it will provide are immeasurable.

Though I saw it with my own eyes, it is still hard to believe that science has advance so far that it seems almost to come out of sicence fiction. The organs will be built using the patients’ unique characters and DNA, it still is astonishing to imagine a doctor quickly publishing an organ and replacing it to the dysfunctional organ without a chance of donor rejection. With this great invention, the life expectancy of cardiopathic patients suffers will be no longer unprecedented . It would be a revolution in the medical field.

Many hold the view that 3D printers can help encourage the production of unlicensed automatic guns, which will endanger the security of the city. While this opinion may be valid in some respects, but the author of the article mentioned that traditional milling machines and other manufacturing hardware can also manufacture the unlicensed automatic guns in the past. In fact, it is still possibly cheaper and easier to get guns in traditional ways rather than using 3D printing. At last count Makerbot, which is making the consumer 3D printers, declaring that he only sold 5200 of them.

Therefore, popular adoption for common mass to have a 3D printer is still far way, and it is too soon to starting dealing with the problem. As with the developing of technologies, some argue that there will be fewer manufacturing jobs available. This argument does not stand its ground, because more maintainers and technicians are needed to fix 3D printers at the same time. Even more, domestic jobs for transporting these products will be on largely vacant. The surplus of manufacturers can compensate the shortage in additional all kinds of jobs.

In conclusion, 3D printing enables the products being sold cheaper and produced quicker, allows more jobs available for labour and potentially improves the life expectancy of human beings by increase the avalibility of spare organ. With respect to the unlicensed guns to be made, a wide range of promotion of the awareness is pivotal, and equally important is the respective punishment on those who break the rules. Therefore, as what Weiberg said, it is not the time to regulate the usage of 3D printing before not completely know the potential benefits what 3D printing can provide.
