After nearly 40 years of development, 3D printing technology has become a powerful tool for advanced manufacturing nowadays, with great development potential. According to Wholers data statistics, the global 3D printing market reached $15.244 billion in 2021, with a compound annual growth rate of 20.4%. According to the China Additive Manufacturing Industry Alliance data statistics, China's 3D printing enterprise revenue reached 26.5 billion yuan in 2021, with an average annual growth rate of 30%, which is higher than the global average growth rate, showing the world's first manufacturing The big country's attention to new manufacturing technologies and achievements.

It can be seen that the market growth rate of 3D printing is quite high, the whole industry scale is growing year by year, but compared with other industries, 3D printing is still a small industry. The reason for this is that the main constraints on the printing efficiency of 3D printing and material costs. For example, based on "point scanning" laser powder bed molten metal 3D printing technology, its aerospace, automotive, military, molds, medical and other fields of small quantities of precision metal parts manufacturing has many applications, but also compared to traditional manufacturing technology has more advantages, but for most industrial users, 3D printing to get a larger scale industrialized Application, there is an urgent need to solve the "slow and expensive" problem.

Binder Jetting (Binder Jetting/3DP, hereinafter referred to as BJ) is a high-efficiency, low-cost "line scanning" 3D printing technology, as early as 1993 was born in the United States at the Massachusetts Institute of Technology, due to the higher threshold of the process, the industry chain is much longer, the development process of the BJ technology lags behind the "dot scan" laser 3D printing technology. "Point scanning" laser 3D printing technology, but by virtue of efficiency and cost advantages, BJ technology is full of energy. In recent years, with a series of technological breakthroughs in the field of BJ, especially the successful development of BJ metal, once again by the industry's widespread attention, known as "Additive 2.0" technology. According to a SmarTech report, by 2030, indirect metal printing technologies such as binder jet 3D printing will realize an output value of 54 billion U.S. dollars (about 350 billion yuan).

Internationally, Desktop Metal, HP, Digital Metal and other companies in the past five years have completed the technical development of BJ metal technology, to achieve a certain degree of industrialization and application. Domestic BJ technology started later, but as a manufacturing country, China's market demand for BJ technology is more urgent, especially from the MIM (Metal Injection Molding) industry for rapid prototyping and small and medium-sized mass production needs. In this context, the rapid development of domestic BJ technology. It is understood that there are several domestic enterprises to BJ as a research project, of which, Beijing Longyuan Automatic Molding System Co., Ltd. (SANDI's subsidiary companies, hereinafter referred to as "Longyuan molding") has been put on the market equipment.

Longyuan Molding Company, a leading 3D printing technology company in China, completed the development of BJ metal technology and launched AFS-J120 and AFS-J380 equipment during 2018-2020. The equipments are built with integrated small particle size (5~15μm) low-fluidity powder precise feeding system, new powder spreading roller pressure system and high-precision inkjet printing system (1200dpi), which can realize ±0.1mm printing precision, >3600cc/h printing speed and >55% green blank density, and the relevant technical indexes have reached the international advanced level.

On the basis of the equipment, Longyuan Forming has successfully developed a series of BJ-specific binder formulations, which are suitable for more than 20 kinds of matrix materials, such as iron-based alloys, light metal alloys, organic glass, ceramics and so on. The team has conducted systematic research and analysis on the physical and chemical properties of the binder and the interaction between the binder and the powder, among which the water-based binder has the characteristics of green environmental protection, sintering low carbon and oxygen residue, etc., which has a good application effect. The degreasing and sintering process is a necessary back-end process to complete the manufacturing of BJ metals. The degreasing and sintering properties of the relevant BJ metal materials of Longyuan Forming have reached the international material standards of the MIM industry, and have the conditions for industrialization and application.

Binder jet metal 3D printing technology is considered to be one of the best ways to realize mass production of metal 3D printing due to its high printing efficiency, low material cost, cost-effective equipment, no additional support, and suitability for batch production, etc. The layout of Longyuan Forming in this field is also the implementation of its development concept of "platform + ecology" based on the core technology of 3D printing. The layout of Longyuan molding in this field is also based on the core technology of 3D printing, to create a "platform + ecological" development concept of practice.

"There are too many orders to do over, just finalized an order with a northeastern customer in the morning, the subject amount is more than 3 million yuan." February 18, spring snow covered the earth, Wugong County Xin Xin Nonferrous Metal Casting Co., Ltd (hereinafter referred to as Xin Xin casting) production workshop a busy scene, this small and medium-sized enterprise has the first introduction of 3DP sand printing rapid casting advanced technology foundry in Shaanxi Province, since the beginning of the spring, the production orders continue to come.

"With the technical support of the domestic 3D printing benchmark enterprise, now we can produce all kinds of complex structure molds, the efficiency has been increased by two times, and the cost has been reduced by half. At the same time, using the sales channels of the upstream enterprises, our casting products are also sold all over the country." Xinxin casting head Tan Dawei said, Gree Electric Appliances, Chery Automobile and other enterprises are their customers.

Just before the first half of last year, the non-ferrous metal casting enterprises are still urgently seeking "breakthrough" way. "The traditional casting process of high energy consumption, high pollution, product precision can not keep up with the requirements of the advanced manufacturing industry, in the country vigorously advocate the development of green casting industry in the context of the traditional casting enterprise development and transformation of the pressure is great." Tan Dawei said, in Wugong County, like them there are five enterprises, are facing similar development difficulties.

Casting industry is the backbone of modern manufacturing, a car has more than 15% parts produced by casting. To high-end, green, intelligent close, is the traditional casting enterprises to achieve high-quality development of the inevitable choice.

From the traditional casting development difficulties, to intelligent transformation of products into market recognition of the "meat and potatoes", Xin Xin casting is how to ride on the 3D printing green casting of the express, so as to enter the transformation and upgrading of the traditional casting enterprises in the fast lane?

It started with an "encounter" between Xianyang Municipal Bureau of Science and Technology and CICC.

"When we docked with CICC Capital for the transformation fund of scientific and technological achievements, we learned that Beijing SANDI Technology Co., Ltd (hereinafter referred to as SANDI Technology), which is led by CICC Capital, had the idea of merging and acquiring casting enterprises, and then we shared this information with the casting enterprises in Xianyang City, and the relevant enterprises were very interested in it." Shen Yan, a staff member of the Science and Technology Bureau of Xianyang City, said that they provided a list of casting enterprises in Xianyang City to SANDI Technology, which paved the way for in-depth cooperation afterward.
At the same time, Wugong County, then in charge of industry and investment promotion work of the deputy governor Liu Wei in the three emperor science and technology chairman Zong Guisheng on the cooperation matters in-depth discussions, after the Wugong County Governor Yao Junfeng also led the relevant departments to Shenzhen to visit the three emperor science and technology companies, and further strengthened the confidence of the two sides of the cooperation.

In this way, a Beijing science and technology, capital and the traditional casting enterprises in Xianyang bridge up. At that time, three emperor science and technology in other parts of the country to investigate the object of cooperation, and Xin Xin casting can seize this opportunity to obtain favor, the key to its success lies in the "efficiency".
"Beijing's enterprises are very efficient, and after indicating our intention to cooperate, we quickly contacted SanDi Technology, and we finalized our partnership in two months' time." Tan Dawei said that with the cooperation bridge built by the Science and Technology Bureau of Xianyang City, their two enterprises with strong complementarity in business quickly found an entry point for cooperation.

"We are interested in Xinxin Casting's more than thirty years of industry accumulation, good business conditions, mature technology processes and the ability to provide efficient, continuous and high-quality services to users. All of these qualities fit well with the strategic layout of SANDI Technology's commitment to building a new ecology for the 3D printing green casting industry." Li Changqing, Deputy General Manager of SANDI Technology, said.

In addition, according to Li Changqing, Xi'an and Xianyang have more scientific research institutes and R&D enterprises, and such customers have a greater market demand for rapid trial production and project validation, and their cooperation with Xinxin Casting located in Wugong County of Xianyang City can further extend their market reach in Xi'an and neighboring cities; on the other hand, the business environment in Shaanxi is getting better and better, and the Science and Technology Bureau of Xianyang Municipality has provided them with On the other hand, the business environment in Shaanxi is getting better and better, and the Science and Technology Bureau of Xianyang City has provided them with great support to look for cooperation opportunities.

After 2 months of negotiation, the two sides 5 times consultation, this CICC capital and the Science and Technology Bureau of Xianyang City, "matchmaking", to realize the innovation elements of cross-regional integration of the cooperation was finalized. Xinxin casting became a subsidiary of three emperor technology holding, three emperor technology in Xinxin casting into the province's first 3DP inkjet sand printing equipment.

"The equipment can realize moldless molding, replacing the traditional casting production line in the mold manufacturing and casting manufacturing links, eliminating the cost and time of opening the mold, eliminating the unreasonable design of the mold and the risk caused by the repair of the mold, high-precision integrated molding, which can be eliminated by splitting the mold, the quality risk caused by the group mold." Xin Xin casting Tan Dawei introduction, the technology can significantly shorten the cycle of product development and trial production, saving development costs, accelerate the time to market, applicable to aerospace, automotive, motorcycle, rail transportation, ship pumps and valves and other fields.

Zong Guisheng: 3D Printing and Enterprise Transformation and Upgrading

　　Dr. Zong Guisheng firstly analyzed the current situation of China's manufacturing industry. Although China became the world's largest manufacturing country in 2010, there are still many problems such as low level of overcapacity, low management level, low technological content and value-added products, and weak technological innovation ability. Facing the loss of cost advantage, forced mandatory elimination, the Internet impact fierce, the industrial environment has changed dramatically the heavy challenges. The transformation and upgrading of Chinese manufacturing enterprises is imminent.
How to transform? Dr. Zong Guisheng believes that we should start from the integration of "intellectual manufacturing" and the social value chain, the integration of "quality manufacturing" and the civilized development of the ecological chain, the integration of industrial chain extension and industrial integration, the integration of new high-tech industries and traditional industries, etc., and ultimately achieve the transformation to "Light", "refined", "strong" transformation.

　　In recent years, from the U.S. Obama administration will be listed as 3D printing to stimulate the return of the manufacturing industry, accelerate the U.S. economic growth of an important "weapon", to Germany's "Industry 4.0" strategy to support the development of a new generation of revolutionary technologies in the field of industrial R & D and innovation, and then the domestic "Made in China 2025" plan clearly to enhance the overall competitiveness of China's manufacturing sector tasks and goals. Made in China 2025" plan clearly enhances the overall competitiveness of China's manufacturing industry tasks and goals, the global manufacturing countries have introduced competitive strategies. Today, with the escalating challenges of global manufacturing, in order to be undefeated in the competition, we need to improve efficiency, shorten the time to market, and enhance flexibility, and these needs have driven the development of smart manufacturing. 3D printing, as one of the core technologies of smart manufacturing, has the great potential to change the entire production industry, and is expected to become the key link in China's high-end manufacturing industry, and to promote the upgrading of China's manufacturing industry.

　　3D printing creates a new ability to produce items of all shapes and sizes, enabling engineers to design more complex products that were previously unattainable.3D printing is widely used in aerospace, automotive manufacturing, foundry, medical, digital construction, civil, and other fields of rapid prototyping and additive manufacturing due to its advantages of manufacturing complex parts, product diversification at no additional cost, no assembly, cloud-based manufacturing, zero-skill manufacturing, portable manufacturing, and net molding. and other fields of rapid prototyping, rapid manufacturing. However, if you do not change the rules, requirements and expectations, 3D printing compared to traditional manufacturing has many defects, can not be used to replace the traditional mature manufacturing methods; and if you change the rules, requirements and goals, 3D printing as another manufacturing method, incremental development, 3D printing will bring a new era of design, manufacturing. Looking to the future, we should apply 3D printing thinking to design and manufacture products, embrace intelligent manufacturing, use 3D printing thinking to design and manufacture products, and promote enterprise transformation.

Lu Chun: "3D Printing is All Around Us

　　Shenyang University of Aeronautics and Astronautics, Department of Aerospace Engineering, Professor Lu Chun pointed out that in the absence of contact with 3D printing before the processing of molds or parts, we usually habitually consider the use of CNC machining of milling processing, that is, subtractive molding process; and familiar with the 3D printing process, it will be used as a 3D printing technology as a way to solve our problems. For example, 3D printing cell phone case, with 3D printing manufacturing carbon fiber tee tube molding mold, manufacturing composite propeller molding mold and composite elevator rudder molding mold, etc. 3D printing makes our life and work easier.

　　For the future development of 3D printing, Prof. Lu Chun put forward several expectations:

　　Can have more excellent mechanical properties and heat resistance. Currently based on resin (plastic)-based 3D printing technology, more than low mechanical properties of PLA, ABS, PS and other resins as a printing material, low mechanical properties, poor temperature resistance, usually only used at room temperature, the ambient temperature is higher than 80 ℃ workpiece of the complete loss of mechanical properties. Many researchers have tried to modify the resin matrix. Such as through the addition of short-cut carbon fiber in the ABS material, the use of carbon fiber reinforced ABS resin, the mechanical properties of the prepared workpiece for the ABS material 30 times; in the resin to add ceramic materials, the use of resin as a carrier, after the row of glue, sintering, glazing and other processes, you can print the workpiece's temperature resistance to more than 1,000 ° C. At present, we and the domestic research institutes are also carrying out the study of this technology. Some progress has been made.

　　Have faster molding speed and higher molding precision. Have the functionality of sound, light, electricity, magnetism and so on. People's 3D printing materials will not only meet the needs of the molding process, but also put forward requirements for the functionality of the material. At present, the research results in this field are beginning to come out one after another. For example, the United States Northwestern University's research team developed a high graphene content can be 3D printing graphite, graphene content can reach 60% or more, it will be given to the printing material thermal conductivity, electrical conductivity. At present, the research and development of printable functional materials is in an accelerated stage of development, and I believe that more products will be available soon.

　　Finally, Prof. Lu shared the current research progress of his team. Its research and development of 3D printer and control software, the use of TCP control communication protocol, and high-precision servo motor closed-loop control, to effectively ensure that the printing process does not lose steps, the printer is currently working continuously and stably for more than 140 hours, there is no model misalignment, filament breakage problems. Its self-developed high-speed printer printing accuracy of 0.025mm, the fastest molding speed of 60mm / hour.

Liu Jianrong: "Research Progress on Titanium Alloys for Electron Beam Fused Wire Deposition".

　　Dr. Liu Jianrong from Institute of Metals, Chinese Academy of Sciences, introduced the research progress of titanium alloy wire for electron beam fusion deposition (EBRM). He pointed out that the metal material 3D printing technology needs to solve the four control problems: control "shape", that is, the shape, dimensional accuracy, equipment, process; control "sex", that is, the performance of the parts, material composition and heat treatment; control defects, that is, pores, porosity, cracking; control costs, that is, materials, processes, equipment, its technological advantages will eventually be realized. That is, material, process, equipment, its technical advantages can eventually be manifested.

　　Electron beam fused deposition is one of the four typical 3D printing technologies for metallic materials. It can realize rapid manufacturing of large structural blanks, filaments, and space in-orbit manufacturing in a vacuum environment. Domestic electron beam fused filament deposition technology has been developed relatively quickly since 2010, and the current technology chain is relatively complete, with balanced development and greater progress in equipment, materials, and process research, and preliminary applications in the aviation field. Titanium alloy is a more ideal 3D printing material, its weldability is good, low tendency of biocrystallization and segregation, cold cracking, thermal cracking phenomenon is not obvious, wide range of uses, physical properties of active, but the cost is high. titanium alloy filaments for EBRM, with the advantages of simple process and low cost. At present, several strength levels of titanium alloy wire have been developed in China to meet the needs of the current stage of development and application of EBRM technology. Domestic EBRM technology is at a relatively advanced level in the research and application of aerospace structural components.

　　For the current equipment "short board" problem, Dr. Liu Jianrong believes that we should actively support the breakthrough of the core technology of the equipment to occupy the strategic high point of the 3D printing industry. At the same time, we should promote the synergistic and rolling development of equipment, materials and processes, improve the equipment (functionality, stability) through the process, improve the overall technical level through the integration of materials, highlighting the advantages of 3D printing technology, and improve the competitiveness of the industry. The government, the association should also focus on the development of the industry, resource integration and effective use, and ultimately achieve win-win cooperation.

　　Dr. Zong Guisheng, Director of 3D Printing Professional Committee of China Powder Metallurgy Industry Technology Innovation Strategy Alliance, Chairman of SANDI Printing Technology Co., Ltd. and Chairman of Shenzhen Seven Technology Co., Ltd. hosted the forum and delivered a keynote speech. Dr. Zong Guisheng said that at present, the global manufacturing challenges are escalating and the manufacturing industry is changing faster than ever. In order to stay in the competition, we need to improve efficiency (especially energy and resource efficiency), shorten time-to-market (shorter development time, ability to manufacture complex products, ability to quickly access and analyze big data), and increase flexibility (large number of personalized products, rapidly changing markets, high productivity requirements), which drives the development of smart manufacturing.

　　The combination of ICT technology and manufacturing gives rise to smart manufacturing. Walking into a future smart manufacturing factory, you can see a variety of independent devices (e.g., 3D printing) that are connected, constantly open, intelligent, software- and data-controlled; machine-to-machine and machine-to-product communication is all about human interaction; the Internet of Things (IoT) triggers and provides information and data for decision-making; information is processed and transmitted in real time; and staff members can make decisions on their own or as a group (societal group decision-making), and the entire industrial ecosystem is going to The entire industrial ecosystem will change profoundly.

　　3D printing, one of the core technologies of smart manufacturing, has a huge potential to transform the entire production industry. It creates a whole new ability to produce items of various shapes and sizes, enabling engineers to design more complex products that could not be realized before.3D printing is widely used in rapid prototyping in aerospace, automotive manufacturing, foundry, medical, civil and other fields due to its advantages of manufacturing complex parts, product diversification without increasing costs, assembly-free, cloud manufacturing, zero-skill manufacturing, portable manufacturing, net molding, etc. , rapid manufacturing. Looking to the future, we apply 3D printing thinking to design and manufacture products, and embrace intelligent manufacturing.

　　The combination of 3D printing devices and the Internet has led to innovations in business models. For example, online platforms that provide 3D printing services and transactions - Shapeways, Ponoko, i.materialise, Everything Print (www.wanwudayin.com), etc. Through these sites, users can purchase design models, order 3D printed products, or open their own stores to sell 3D printed products, designs or materials. This new business model is called D2C - Designer to Customer, and it not only fulfills an individual's desire to create, but also translates into commercial profitability, which in turn will surely further drive the growth of personal 3D printing demand. What Chris Anderson calls "creativity" is the key to the success of 3D printing. Anderson said the "creators" era is step by step into reality.

In addition, 3D printing in the field of innovation and entrepreneurship in the application of great advantages: can improve the efficiency of customization, reduce the design, research and development, trial production, customization and other aspects of the cost of design, R & D, research and development, production of the trinity, and at the same time to avoid the leakage of the design of the sketches, to achieve the effective protection of intellectual property rights. In the future, 3D printing will be fully popularized in domestic primary and secondary schools, and gradually from the school into the family.

Ms. Li Lei, Senior Engineer, Project Manager, Resin Application Research Institute, Beijing Yanshan Petrochemical High-Tech Technology Co.
　　Ms. Li Lei, Senior Engineer, Project Manager of Resin Application Research Institute of Beijing Yanshan Petrochemical High-Tech Technology Co., Ltd. and Sinopec Beijing Yanshan Branch, introduced the application and development status of resin materials in 3D printing. polymer materials used in 3D printing mainly include thermoplastic plastics, photosensitive resins, rubber materials, composites and so on, while materials with great future prospects such as biomaterials, cellular materials, DNA framework materials and stem cell materials are also in the research and development stage. Biomaterials, cellular materials, DNA framework materials, stem cell materials and other materials with great future prospects are also in the research and development stage, and there is a huge space for imagination. From the current application of China's 3D printing market, ordinary materials occupy half of the market, domestic self-developed mid-range material products accounted for about 40%, foreign high-quality imported consumables accounted for 10%. For the future application of 3D printing materials, such as Yanshan Petrochemical Resin Application Research Institute, such as the authoritative scientific research institutions will be committed to the development of more special-purpose consumable products for specific requirements to develop more functional products. In view of the future application prospect of 3D printing materials, authoritative research institutes such as Yanshan Petrochemical Resin Application Research Institute will be committed to developing more special-purpose consumable products, developing more functional products for specific requirements, and improving the applicability of materials and 3D printing equipment.

Dr. Zifu Li, member of 3D Printing Professional Technical Committee of China Powder Metallurgy Technology Innovation Strategy Alliance, Deputy General Manager of Shenzhen Seven Technology Co.

　　Dr. Zifu Li, member of 3D Printing Professional Technical Committee of China Powder Metallurgy Technology Innovation Strategy Alliance, deputy general manager of Shenzhen Seven Technology Co. Ltd, and technical director of Beijing Longyuan Automatic Forming System Co. Ltd, analyzed the application key technology and development trend of metal 3D printing. Data show that in 2014, the global additive manufacturing market scale is about 4.1 billion U.S. dollars, metal 3D printing equipment amounted to 546 units, showing a high-speed growth trend; the direct printing of functional parts will become the main application direction in the future. Metal 3D printing, as a high-end additive manufacturing technology capable of directly manufacturing high-performance metal functional parts in three dimensions, has been planned and laid out from the national science and technology development strategy level. At present, it has been widely used in aerospace, automotive, medical and other fields. For example, Beijing Longyuan molding in June 2015 successfully passed the "Zhongguancun Industrial Technology Alliance major application demonstration project" expert group acceptance, with direct metal 3D printing equipment development and production capacity.

　　High-quality metal powder material is the realization of high-performance products printed on the premise of the foundation, and the current metal additive manufacturing equipment monopolized by foreign high-end products, due to the existence of equipment and materials adaptability, which in turn formed a monopoly on the supply of foreign metal powder material. Foreign brands of metal powder is expensive, long supply cycle, if it involves sensitive materials, but also by foreign export restrictions. Therefore, the realization of additive manufacturing metal powder localization is imperative.

　　Looking forward to the future development of metal additive manufacturing, Dr. Li said that in terms of materials and processes, it is necessary to improve the diversity of materials, develop domestically produced metal powder materials with cost advantages, strengthen the in-depth fusion of additive manufacturing technology and traditional material molding technology, and set up a large database integrating the design and preparation of powder materials, optimization of the additive manufacturing process, and optimization of the subsequent processing process, etc.; in terms of equipment systems, it will be Tend to molding space is bigger, additive manufacturing process monitoring system is more intelligent, equipment specialization, "metal additive manufacturing +" intelligent manufacturing mode, etc.; application, will tend to the direct manufacturing of functional parts, medical and health fields, automotive and aerospace fields.

Dr. Xie Yanjun, Director of Academic Department, China Steel Research Technology Group Corporation, China Powder Metallurgy Industry Technology Innovation Strategic Alliance

　　Dr. Xie Yanjun, Director of Academic Department of China Steel Research Technology Group Corporation and China Powder Metallurgy Industry Technology Innovation Strategic Alliance, analyzed and introduced the development status of metal additive manufacturing (3D printing). He said that metal additive manufacturing is an important part of additive manufacturing technology (3D printing), which has great advantages in solving the problems of difficult-to-machine materials, complex structures and rapid manufacturing in industrial production. As the most technically difficult and fastest-growing market potential and growth area in the additive manufacturing industry, laser additive manufacturing of metal parts has high strength, dimensional accuracy, watertightness and lightweight characteristics, and has been applied in aerospace, defense, medical, automotive, electronics and other fields.

　　For the current development mode of "heavy equipment, light materials, light process" in the field of additive manufacturing in China, Dr. Xie Yanjun believes that the development of additive manufacturing technology is a whole industry chain work combining equipment, materials, process and application, and in addition to increasing the investment in research and development and overcoming technical barriers at the national level, it is also necessary to organize the industry alliance to give full play to the advantages of each unit and integrate resources to form a platform development mode, which is of great significance to the rapid development of China's additive manufacturing industry. In addition to increasing R&D investment and attacking technical barriers at the national level, it also needs to be organized by the industry alliance, which will give full play to the advantages of each unit, integrate resources, and form a platform development mode, which is of great significance to the rapid development of China's additive manufacturing industry.

Conversation with Entrepreneur I: Zong Guisheng, Chairman of the Board, SANDI Printing Technology Co.

Zong Guisheng: As a student out of entrepreneurship, including some from the teacher now retired to start their own business, will encounter some views, in the face of these various arguments and views, how did you deal with it?

Liu Jiren: At that time in fact should be very entangled. The school called me general manager, I went back at night because of this can not sleep. But I later figured out that you live for your own dreams? Or for others? In the beginning, you want to get everyone's applause too much, you may lose the goal of struggle; and you stick to the goal of struggle, if you go well, then you will also get (applause) in the future. So I think it's more important to love yourself and your dreams than to love others.

Zong Guisheng: So it's important to have a firm, clear goal to rush towards, and leave the rest alone?

Liu Jiren: Yes.

Zong Guisheng: The core technology of the third industrial revolution is ICT technology, that is, information and communication technology. I've noticed that Neusoft has a lot of solutions in manufacturing, and now there's not yet, for example, like an MIS system. Isn't it an appropriate time that we should start to have our own national system?

Liu Jiren: It will have two parts in the future. One is an information technology system for knowledge-based manufacturing. I think China's manufacturing enterprises in the past is very remarkable, to control this cost so low, which has a lot to do with their use of a lot of information technology in the past 20 years. How can manufacturing and communications, software and other IT can be combined to enhance its added value, and the space for this, I think, is still just beginning. For example, how can we have robots for home care at home? Then this one has technology for recognition and communication; it has assistive technology, it might help the elderly to come to the police, and this one is artificial intelligence, large-scale big data and cloud computing. So I think this must be a new beginning. Germany called "Industry 4.0", China called "Internet +", heralding a cross-border integration, the integration of technology, is a trend of future development. (Source: Tencent Finance "Choice")

　In May 2015, the technical support of the marketing department of Beijing Universal Precision Technology Co., Ltd, the controlling subsidiary of SANDY Printing Technology Co., Ltd, was invited to support the paraplegic support project of Guangxi Disabled Persons' Federation in Liuzhou, participating in the whole process of patient screening in the countryside, pre-assessment, RGO production and guidance of rehabilitation training for the patients in the later stage, which was highly evaluated by Liuzhou Municipal Government, and gained the unanimous thanks and praise from the families of the patients.

　　It is reported that fitting 50 poor paraplegic disabled people with braces free of charge and guiding them in rehabilitation training is one of the practical projects for the people of Liuzhou Municipal Government in 2015. In order to ensure quality and efficiency, Wang Xiao, a well-known domestic orthopedist from Beijing Global Jingbo Rehabilitation Auxiliary Technology Co., Ltd. was specially hired to provide technical guidance throughout the whole process.
