On September 10, global 3D printing giant 3DSystems announced the acquisition of SugarLab. The latter is a Los Angeles-based startup that specializes in "printing" desserts for customers-first build a mathematical model according to customer requirements, and then print out desserts that meet food safety requirements and have different tastes. This is another latest case of frequent mergers and acquisitions in the global 3D printing industry since US President Barack Obama announced in June 2011 that he would spend US $ 500 million on the 3D printing industry in order to revive the US manufacturing industry, thereby detonating the global 3D printing boom.
With adequate rest, you can go farther and climb higher. Sleeping is definitely a big problem when we are camping outdoors overnight. How can we sleep comfortably and warmly in the wild?
When camping, we usually lie directly on the ground, and we will soon feel the loss of body temperature, and the inflatable sleeping pad can isolate the body from the ground.
â— A good outdoor blow up sleeping pad, let the outdoor life, have a little happiness that makes the corners of your mouth rise. DOING inflatable sleeping pads are heat-insulated, moisture-proof, comfortable, lightweight, and easy to operate.
â— At the same time, DOING supports customized Triangular Core Matrix technology. The technology uses two stacked layers of triangular baffles to create a stable surface while minimizing heat loss. To achieve good thermal performance, it is suitable for all seasons and can also cope with extremely cold and low temperatures.

In December 2012, Stratasys (SSYS: Nasdaq), another giant 3D printing equipment manufacturer, announced that it would merge with Israeli 3D printing company Objet, thus surpassing 3DSystems in scale, with a close to 50% share in the professional 3D printing equipment market Ranked first.
In June of this year, the merged new Stratasys merged MakerBot again with a $ 403 million share swap transaction. Unlike professional-grade 3D printing vendors such as 3DSystems and Stratasys, MakerBot provides desktop-grade 3D printing equipment. The transaction means that 3D printing is accelerating penetration into the mass consumer market.
The capital market also voted by hand on the 3D printing boom. Based on the closing price on September 12, 3DSystems' share price has risen from $ 25.73 a year ago to $ 51.49, an increase of 103%. Stratasys' share price has risen by as much as 756% in the past year.
"3D printing is constantly growing into a big business." On September 13, Liang Zhichao, deputy general manager of Guangzhou Guangya Frankfurt Exhibition Co., Ltd., said in an interview with the author that 3D printing has unique value in personalized customization and new product verification. However, it is not enough to support large-scale production. The formulation of the "third industrial revolution" is still too early to say.
"Cannot print yourself"
Guangya Frankfurt Exhibition Co., Ltd. holds a well-known mold exhibition in Guangzhou every year. "Last year, only sporadic 3D printing companies participated." Liang Zhichao said that there were 24 3D printing companies participating in the exhibition this year, and the organizer set up a special 3D printing area for this purpose.
Liang Zhichao said that 3D printing is a future-oriented technology. At present, domestic and foreign companies are competing for layout, especially in the automotive, aerospace, industrial and healthcare industries. According to data from the Consumer Electronics Association of America, total sales of 3D printing products designed by the above industries will reach US $ 5 billion in 2017, a multiple increase from US $ 1.7 billion in 2011.
"As of now, I haven't heard of any 3D printer in the world that can 'print' a 3D printer." Liang Zhichao said, unable to print himself, is actually an image embodiment of the limitations of 3D printing. Traditional mold industry. "
In fact, from the analysis of the exhibitors at the Guangzhou Die & Mould Exhibition, it is not difficult to see the mainstream status of traditional molds. There will be more than 400 exhibitors in the "2013 Mould Exhibition" to be held in Guangzhou Poly World Trade Expo from September 24th to 26th, and the proportion of traditional mould companies is as high as 95%.
Compared with the global sales of 1.7 billion US dollars in 2011 for the global 3D industry, the output value of the mold industry in China alone exceeds 200 billion yuan, and the export value is about 140 billion yuan.
Xiao Guodong, general manager of Tianjin Weishen Technology Co., Ltd., told the author that high cost is currently a major obstacle to the 3D printing industry. From the perspective of professional-grade 3D printing equipment, a metal-based 3D printer costs 5 million to 6 million yuan, and a plastic-based 3D printer costs one or two million yuan per unit. The price of 3D printing equipment produced by domestic enterprises is slightly lower, and it is also 8 million to 900 thousand yuan, and the low price is 4 million to 500 thousand yuan.
At the same time, since 3D printing manufacturers generally adopt the mode of raw material bundling, the cost of raw materials should not be underestimated. Xiao Guodong said that the plastic used for 3D printing is about 2000-3000 yuan / kg.
He believes that the popularity of 3D printing in the future will depend on the full competition of the industry and the reduction in the cost of equipment and materials after technological progress. "If the cost does not come, there is no way to scale."
In addition, Xiao Guodong said that the current 3D printing time of a complex piece is also more than ten hours, and the time cannot meet the efficiency requirements of large-scale production.
"We participated in several 3D printing exhibitions this year. There were many people who came to consult, but very few actually placed orders." Xiao Guodong revealed to the author. The Tianjin Weishen Company where he works is mainly engaged in 3D scanning business, which is another important link of the 3D printing industry chain in addition to printing equipment and raw materials. A 3D printer needs to print a personalized product based on a three-dimensional model, and the three-dimensional model is either formed by three-dimensional image design or obtained by scanning.
Xiao Guodong admits that at present, the company's revenue from 3D printing is still very small. The customers of 3D scanning mainly come from the traditional industries such as the reverse detection comparison of drawings and entities, and the display of 3D samples.
Liang Zhichao said that due to factors such as high cost and long printing time, 3D printing can only be used for small batch production in some areas. More mature applications such as the hearing aid industry, "Everyone ’s ear canal is different. According to the scanned model for personalized customization, the application of 3D printing is very full. "
Guo Taiming, chairman of the foundry giant Hon Hai Group, also scoffed at the idea of ​​3D printing technology as the "third industrial revolution", and said: "If it is really, then I wrote the word" Guo "upside down."
