3D printing popular in global manufacturing opens a new revolution in China's industry

3D printer, one of the flag products of the third industrial revolution. Born in the United States more than 20 years ago, it has been popular in the global manufacturing industry in recent years. The Chinese company Nanjing Zijin Lide is the leader in this trend, and has also created its own 3D printer and brought it to market.

“This 3D printer can cut, stack and then practure the pvc film according to the 3D data in the computer. The printed product is durable and can be punched and polished on it.” Nanjing Zijin Lide Company is responsible for The manager Cai Shaoquan said that.

In fact, toys are just a partial display of the capabilities of 3D printers. At present, the world's products successfully manufactured by 3D printers include: high-precision braces, artificial bones, jewelry, rifles, statues, shoes, toothbrushes...and even cakes. The variety, the shape, and the lightness of the materials are amazing.

"There are many foreign scientists who still use it to print houses, cars and even planes!" Cai Shaoquan said.

Why is there such a big "magic" in 3D printers? Luo Baihui, secretary general of the International Association of Mould & Hardware Plastics Industry Suppliers, said that this technology was first used in the construction and mold design industry. In the past, when designers changed the product from a drawing to a prototype for the customer, they needed to make the mold first and then cast it. Or use a lathe to cut metal materials. This method is costly and encounters complicated products and the production cycle becomes very long. 3D printers have abandoned these cumbersome procedures. Through the 3D design drawing created by the computer, the printer performs a "slice" scan on the stereoscopic prototype to accurately grasp the size of the finished product, and then sprays the raw materials layer by layer to the designated position through the nozzle, and then "sands into a tower" to complete the work. If you add chocolate powder and cream, it is not surprising to print a chocolate cake.

The British "Economist" magazine said in a report in April this year that 3D printing technology will make the factory completely say goodbye to traditional tools such as lathes, drill bits, punching machines, molding machines, etc., which is more flexible and requires less investment. The production method is the symbol of the arrival of the third industrial revolution. The traditional manufacturing industry will gradually lose its competitiveness, and digital, artificial intelligent manufacturing and new materials will be widely used.

At present, the two companies that produce large 3D printers worldwide are listed on NASDAQ in the United States. Their 2011 revenues were $170 million and $290 million, respectively. Many Fortune 500 companies are their customers.

According to The Economist magazine, the revenue growth rate of the 3D printing industry will reach more than 50% in the next few years. The US "Time" Weekly has included the 3D printing industry as "the top ten fast-growing industries in the United States."

In China, there are also many companies with technological advantages who are “in the first place” to invest in this field. In September this year, A-share listed company Nanfeng Co., Ltd. announced that its subsidiary will invest in “heavy metal component electrofusion precision molding technology project” with a total investment of 168 million yuan. According to Luo Baihui, the project is known as the 3D printing technology in the world, and the profit prospects are very promising.

3D printers not only revolutionize the industrial field, but also provide a space for cultural creativity. Last year, Song Bowen, who graduated from the Central Academy of Fine Arts, opened a custom-made studio in Beijing. In addition to producing and selling limited edition 3D printed artwork, the studio also cooperates with some interior design companies to realize the concept of “natural creation” through 3D technology.

In June of this year, she won the runner-up in the "World 3D Print Exhibition" in Belgium with a "top hat" made by 3D printer. The "top hat" is made of purple resin. It has a delicate shape, a hollow hat and a complex pattern, and a few "flowers" that can be used to make people look a little more. And the weight is almost the same as the general hat.

The 3D printer is an opportunity. The imagination of the designer has always been shackled, and now the product can grow freely like a creature. Can really help me achieve the desire for free styling. 3D printers can be used not only for design, but also for their ability to shape cultural relics.

The Tianlongshan Grottoes in Taiyuan, Shanxi Province were looted in the 1930s. The statues were scattered around the world, and most of the existing ones were ruined. Hangzhou sculptor Li Qinghua and his friends spent half a year scanning all the 3D data of the 18th cave of Tianlong Mountain. It took another half a year to spell out the three-dimensional graphics. Now, they have completed the three-dimensional reproduction of the 18 cave statues.

Cleaning Products

Microfiber cleaning cloth using microfiber (microfiber), not only will not cause damage to the product, and even fine dust can also be removed clean, is a high performance cleaning cloth. Chemical detergent usage is small, is a beneficial to the environment environmental protection products. Compared WITH ordinary cotton products, the water absorption speed is faster, and convenient to remove pollution substances, when used as a variety of cleaning cloth and towel, can play an excellent effect.

Ningbo Jenny Import and Export Co., Ltd. focus on OEM customization, has its own factory. More than ten years of production experience. Can provide microfiber terry cloth, microfiber Gloves, microfiber mop and other products customized processing, the company adheres to the core competitiveness of technology and service as the guidance, to the customer as the center, is a number of foreign shopping malls, car wash, glasses factory and other cooperative manufacturers.
