With regard to 3D copying, the industry has two distinct ideologies: this speculation will promote the third industrial explosion, and this belief that it has no economic benefits.

On the 24th, Lu Bingheng, the president of the School of Mechanical Engineering of Xi'an Jiaotong University and the top biologist of the National 973 New Project, who came to Jiangning, Nanjing to participate in the initiative of China's 3D copying seminar, undertook a news reporter interview. He said that today's 3D copying discussion and development and design are still in the exploratory period. It is too early to call it "industrial explosion", but it does cause serious harm to the research and development of goods, and will promote the production of humanized goods, Neglect and neglect of its development prospects are also excessively negative and depressing.

The academic research name of "3D copying" is "professional skills of rapid forming". According to the statistical data of 3D modeling of parts or blocks, after forming machines and equipment, the solid models are made by accumulating raw materials.

"Goods manufacturing does not require CNC blades, jigs and fixtures and CNC lathes. Ideas and overall planning can be drawn on the computer, and can be turned into goods after the copier, which is really wonderful!" The theorists, taking The Economist as an example, conjectured that 3D copying "overthrows our traditional basic theory and definition of (manufacturing industry) and is the expression form of the third industrial explosion".

But the industry is not so optimistic.

At the 2013 Taiwan, China Plan Display Display Fair, Gou Taiming, a manufacturing giant and Hon Hai's boss, believed that 3D copying was by no means equivalent to the third industrial explosion. Hon Hai had used 3D copying expertise 30 years ago, but it could not be mass produced from commercial activities.

He took the telephone made of 3D copy as an example to show that this article can be made, but it can only be seen, not used; No more electronic components can be added, which cannot be converted into mass production of electronic components.

"(3D copy) If it is (effective), my word 'Guo' will be written backwards.

”Lu Bingheng, an academician of the Academy of Engineering, founded the "National Engineering Project Research Institute for Rapid Production and Manufacturing", which is a backbone teacher at the level of 3D copying, and is known as "the leader of 3D copying in China".

In his view, the prediction of the theoretical community is just such a future outlook, which requires time to check.

Lu Bingheng introduced in detail that the "novel meaning" of today's 3D copying, a large number of soil layers are now in the development and design of goods.

For example, the research and development cycle of the airport is about 20 years, and the development progress of the car is one or two years, which takes so long. Because some key components and parts require a lot of repeated tests, for example, the diesel engine parts of American aircraft require up to 2500 tests. If traditional manufacturing is adopted, it takes time and effort, and the risk is huge. 3D professional skills can be active, rapid The overall planning in the electronic computer can be immediately and accurately converted into a solid model, or even parts or abrasives can be made immediately to reduce the research and development cycle time, develop product quality and reduce production costs. The process flow that was completed in the past many months can now be completed in a few days or hours.

"For manufacturing, R&D is more critical than production capacity.

”Lu Bingheng introduced in detail that the British scientific and technological circles estimated that after 3D copying, the product development cycle time and cost were more than half of those in the past, which greatly shortened the product upgrade cycle time and developed the competitiveness of enterprises.

In addition, 3D can also "copy" goods that cannot be produced by traditional manufacturing, such as unusual diesel engine parts, and extremely functional artificial service bones.

Xi'an Jiaotong University has experienced the professional skills of 3D copy docking microbial simulation, and has produced titanium artificial service bone for medicine, which is divided into hyperosteogeny layer, cancellous bone layer and spinal cord layer from the outside to the inside, just like the body bone.

"Therefore, if 3D copying will cause 'subversive harm', it will have to go through the process of intelligence, artificial intelligence technology manufacturing and new materials. 3D copying alone cannot accomplish such a serious task.

”China has become a powerful manufacturing country. It is required to be a good university. Contact information content professional skills, raw materials, high-tech, and 3D applications must be able to find a breakthrough.
