In 2013, a technology term appeared more frequently in the public's field of vision in 3D printing.
"Like the steam engine of 1750, the printing of 1450, the transistor of 1950, 3D printing will also change the world in a long time." The Economist magazine puts 3D printing on the altar. It seems that 3D prints such as Aladdin's magic lamp, only you can not think of, can not do.
For Dongguan, the “capital of the processing industryâ€, 3D printing is still a long way away from citizen life, but it has gradually begun to be used by some companies.
Citizens:
Over 70% of respondents are willing to adopt fresh 3D printing
What is the impression of 3D printing technology in the hearts of the citizens of Dongguan? Dongguan citizens learned about 3D printing from various types of information channels. Many said "It looks beautiful, but it is very far."
Over the weekend, the reporter distributed 200 questionnaires to the public in the form of websites, QQ groups, and on-site investigations. From the feedback, despite the previous Gabo meeting, 3D printing technology had a gorgeous appearance and won many praises. However, more than half of the people still do not understand the technology.
Mr. Meng, a citizen who had visited Gabo Fair, was very impressed with the 3D printing technology displayed at the meeting. However, Mr. Meng believed that the time for mass popularization was at least 10 years. He said, “I have witnessed 3D printing technology with my own eyes. I am very optimistic about it. I am optimistic about its prospects. More than a decade ago, mobile phones could only make calls and send messages. After many technological changes, the current mobile phone has been Combined with multiple functions, the development of 3D printing technology should be the same."
"At present, 3D printing technology is not yet very mature, I believe that after a certain degree of perfection, the function will be more and more powerful, but now it seems that this process takes at least 10 years." Said Ms. Gao with the same view.
If 3D printing technology eventually goes to the streets, citizens can easily purchase gifts or crafts that have been printed through it. Will most people purchase them? More than three-quarters of the people who affirmed or may buy, and only one-fourth of those who made it clear that they would not buy it. As Miss Ci Su said, "After all, it is a brand-new technology. If the workmanship is exquisite, many people are willing to take advantage of it."
As for the ultimate use of 3D printing technology, nearly half of the public believe that it should be used for industrial production. At the time of the eventual popularity, the public is also very concerned about the use of printed gifts or artworks as an example. The price that most citizens can afford is less than 500 yuan, while less than 20% of the citizens can think that they can accept more than 500 yuan.
For the future of 3D printing technology, 56% of the people think that the prospects are bright, but at the same time, a quarter of the people are not very optimistic. As for its ultimate popularity, most people have expressed that they must be at least 10 years or more, and the percentage of citizens holding this argument is as high as 62%.
expert:
3D printing will not replace traditional mold making
According to Zhou Weirong, director of the Collaborative Innovation Office of Dongguan University of Technology, 3D printing technology has obvious advantages in the mold manufacturing field.
He believes that the market is very fast in updating products. If a new product is produced, if it does not sell well, it will not be worth the candle. It takes hundreds of thousands, or even millions, to develop a mold. With the use of 3D printing technology, products can be developed first. If technical requirements and market requirements are met, mold development is carried out to further mass production.
The advantage of using 3D printing technology is that it can greatly shorten the production cycle and save production costs. For example, the use of conventional manufacturing techniques for a profiled waterway of a mold is difficult, and it takes at least five people to complete it in about 12 working days, sometimes resulting in material waste.
However, the use of 3D printing technology can be completed in 73 hours, but also has the characteristics of high precision, so that we can continuously improve the competitiveness of the market, to seize the opportunity in the development.
In addition, some people have misunderstood the 3D printing technology and think that 3D printing technology will replace the traditional mold manufacturing technology. It is not true, Zhou Weirong believes that the two are complementary.
Cases
It is understood that 3D printing technology is currently used in jewelry, footwear, industrial design, construction, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.
For Dongguan, the "capital of the processing industry," a revolution in manufacturing is bound to bring about changes. However, a number of industry sources told reporters that limited by technological development and material restrictions, currently in Dongguan, 3D printing technology only appears in some molds, automation, creative animation, design and other fields of enterprises and universities.
Canton 3D printers sell for 5.6 million yuan each
Hongtai Automation Equipment Co., Ltd., located in Huiying Mould City, Hengli Town, has provided 3D printing technology services since 2007. According to Wu Xiaogang, general manager, the popularity of 3D printing technology has become a trend. “We used to buy machines from Shanghai. The material used was photosensitive resin, and the machine price was about 890,000 yuan. But the surface of the product was insufficient. Refined, customers are not satisfied."
At present, the company's customers are all over the country. In order to meet customer requirements, in April this year, Hongtai Company successfully developed its own 3D printer. The printed product not only has a higher degree of refinement, but also the price of each device has dropped to 560,000 yuan. Wu Xiaogang stated that it has already produced 2 sets and will increase to 5 sets in another month. Later, their company will not only continue to expand its 3D printing service, but also increase the sales of its machines.
At the same time, the company is cooperating with Dongguan University of Technology to develop 3D printing equipment for photosensitive resin materials used in the production of hand boards and models. The development of the first round of prototypes has been completed, and preliminary industrial tests have been carried out. It is expected that the amount will be realized next year. Production.
Small desktop 3D printer Taobao has sold 10 units
At the end of last year, the Rapid Prototyping Innovation Group of Dongguan University of Technology successfully developed a small desktop 3D printer called “Small Cubeâ€. Relevant person in charge introduced that since January of this year, they have sold 10 units on Taobao, each priced at 3,000 yuan. The buyers are mainly engaged in related education, small and medium-sized designers and DIY enthusiasts.
The ABS plastic needed for the printer is commercially available. The quality varies from price to price, ranging from RMB 100 to RMB 1,000 per kg.
