Printing is involved in 3D printing, waiting for opportunities and technological stability

[China Packaging News] (author: panxiaodong) what is 3D? 3D is the English abbreviation of three-dimensional combined printing, which is three-dimensional forming

for some time, 3D printing has become a very heated topic in the printing industry in the transition period, just like talking about digital printing in those days

the promotion of 3D printing is a little too much! To publicize a new technology that is still in the transition from laboratory to development and production as a technology that is mature enough to be widely used is to attract attention to a certain extent

clearly understand the development of a new technology, accurately control the market trend of new technology, and timely choose the opportunity to enter this field are three completely different concepts. As a profit-making enterprise, what it needs is to carefully observe, calmly think, and accurately judge the PS version, and never follow others and rush into mass action

what is 3D printing

3d printing is a new field related to printing but completely different from traditional printing.

two years ago, people in China probably seldom heard the professional vocabulary of 3D printing, because the new technology of additive manufacturing is completely different from the common material reduction (cutting) manufacturing in the era of industrial economy, and it is closely linked with the development of computer technology. Before 3D printing became the focus of social debate, additive manufacturing was mostly in the stage of laboratory scientific research. Even some applications were only in extremely limited fields such as medicine and aviation, and now it began to gradually move towards the market

paper packaging according to professionals, the so-called 3D printing is a comprehensive and systematic technology that integrates computer software, materials, machinery, control, network information and other multidisciplinary knowledge. In principle, it generally includes five links: three-dimensional modeling of products, generation, transmission and acquisition of slice data, scanning of materials layer by layer by beam, melting of materials, and layer by layer superposition of materials. According to the different process equipment and materials used, 3D printing technology can be roughly divided into: powder material high-energy beam sintering or melting forming, filiform material melting deposition (FDM), liquid resin curing forming, liquid ink-jet printing forming and so on

at the International Summit Forum on 3D printing technology and the future, which was first held in Shanghai by Hong Kong iFLYTEK exhibition company in December 2013, Professor Wang Huaming of Beijing University of Aeronautics and Astronautics wrote an inscription for the Journal: additive manufacturing/3d printing: the development direction of advanced manufacturing technology. The inscription of an overseas vice president named Bart van der schueren is: 3D printing is an emerging technology that subverts the design industry. In the financial crisis, it can customize products that are absolutely value for money for customers. We will see that there will no longer be unnecessary waste in design, and there is unlimited and unrestrained development space in design itself. This is why 3D printing has become a new darling of modern industry. These two inscriptions clearly illustrate the scope of application, process expertise and significance of 3D printing technology in production

3D printing, which belongs to the manufacturing industry, seems to have nothing to do with printing, because printing is only an applied production technology about copying and lifelike restoration of images and words, and it does not involve the problem of reducing or adding materials in the production process of printing. Why do the two that don't intersect now come together? First of all, this is because 3D printing has a lot of data processing work before it is put into production. Packaging printing has something in common with the printing industry, which is most closely combined with computers. Secondly, because of production needs, printing entered this data processing field earlier and accumulated some experience through practice. Moreover, when the printing industry has overcapacity and urgently needs transformation and upgrading, people hope to solve the existing problems by extending the industrial chain, so printing has entered the ranks of 3D printing. It must be pointed out that 3D printing is not only capable of printing, and other related industries can also be involved

the above situation tells us that even if printing enters the ranks of 3D printing industry regulations, they are relatively good at data processing before production. As for the grasp of printing materials and the production process differences between different materials, they are just novices. Although some printing enterprises have introduced 3D printing equipment, they still have a long way to go to full production and expect to make profits for enterprises through printing. For all printers, at present, perhaps more should be to understand this emerging process and calmly observe its growth rather than rush into this field

how will 3D printing develop

the key to the development of 3D printing lies in the breakthrough of material technology

after a preliminary understanding of 3D printing, what will its market trend be? The conclusion may be: on the one hand, let more objects know about this new process through market operation. On the other hand, in order to invest in the large-scale practical application of wine packaging, it is necessary to increase the research on new materials. Only in this way can it be possible to reduce the application cost, and expand the application field is based on such significant advantages

as digital printing meets personalized customization, the biggest advantage of 3D printing also lies in on-demand manufacturing. From the 3D printing products in the exhibition, because the water supply/moistening plate is formed by printing at one time, the complex and mutually occluding gears can mesh and rotate after printing. The internal hollowed out products that originally need to be completed through extremely complicated processes can also be formed at one time through printing, and the process is greatly simplified. But also because of its new, so far 3D printing also has some shortcomings that cannot be underestimated. For example, in ink-jet printing, the surface finish of products formed by stacking and solidification (such as resin) or sintering (such as metal) is far less than that of products completed by traditional cutting technology; Due to the limitations of technology and materials, the manufacturing breadth of some products is also restricted, and the hardness or flexibility of products is far inferior to those of metal parts that are traditionally cast or repeatedly rubbed by hydraulic presses

consumables according to the existing reports, the current application of 3D printing is mainly in the field of scientific research, and various attempts are still being made. For example, 3D printing has the ability to produce housing printing materials, but the cost of printing officially used in building houses is obviously much higher than the existing construction technology. British scientific research institutions have also adopted printing technology, which will be the first attempt to treat the garbage since it was discovered in 1997. The 1.2-meter titanium wing parts have been printed, but it is not possible to print larger parts at present. At present, the concept left to me by product publicity seems to be that many 3D printing methods can be done, but it is far from that consumers are willing to use printing methods, because the printing materials are far from keeping up with the actual needs, and the printing products are still lack of excellent cost performance. In the exhibition, we can see very lifelike sports shoes, but the cost of printing a pair of sports shoes is obviously incomparable with traditional technology production, and consumers will not give up this and that. Just like the current digital printing products, before their cost performance is lower than that of traditional offset printing, although they can do a lot of work, the actual market share is still difficult to compete with offset printing. They can only wait for further technological innovation. Shaanxi beiren, with the reduction of the price, will gradually encroach on the market

3d printing certainly has advantages that traditional manufacturing does not have. The product samples provided for the design are printed to give the designer or user an intuitive feeling, which is convenient for the formal batch production after appropriate modification and improvement. Although the price of printing is quite expensive, it still has advantages compared with special mold opening. Moreover, the packaging design, for products with complete personality such as human bones and teeth, because the scanning data can be more accurately matched, the products formed by 3D printing are obviously more suitable. According to the introduction of relevant professionals at the summit forum, even though 3D printing can not really print human organs for practical use, using small organs that survive printing for clinical drug trials can greatly reduce the high risk of relying solely on human trials

since 3D printing is a prepress process of value-added manufacturing, the key is data acquisition and material selection. With the continuous improvement of computer ability, the obstacles in data acquisition are relatively small, and the obstacles in materials are the most obvious, because whether it is high-energy beam sintering or melting forming, filiform material melting deposition forming, liquid resin curing forming or liquid inkjet printing forming, it is ultimately related to materials. At present, there are relatively few materials to choose from for book printing, and the price is high. In particular, our country basically depends on imports, which further pushes up the cost of value-added manufacturing. Therefore, the breakthrough of materials is the key to making 3D printing truly enter the application market. Paying attention to the development of 3D printing technology, in the final analysis, is to pay attention to the continuous technological breakthroughs of 3D printing materials

the above analysis can make us realize that although 3D printing has reached the stage that it can be used, investment and procurement have enabled people to see the bright future of 3D printing and that digital technology is changing the traditional manufacturing industry, but it is too early to expect to enter large-scale applications. Unless printing enterprises have relatively stable business volume, they will undoubtedly lose money and can only be regarded as pioneers at best

when will 3D printing be involved

we should wait for the further maturity of 3D printing technology and the diversification of material supply

since the fundamental reason for the rapid entry of 3D printing into the market is the cost-effective UV printing of products, it will take some time to change this situation. Therefore, it is obviously inappropriate for printing enterprises in the process of transformation and upgrading to rush into this field

at the international printing exhibition held in Shanghai in July 2013, Shanghai printing (Group) Co., Ltd., as a national printing demonstration enterprise, can also adopt the clamping method) industry, showed the 3D printing equipment they introduced and the precious Buddha statues that still exist in Xinjiang guici cave printed with the equipment according to the original collection 1:1. Although the printed products are lifelike, they have been colored by the staff of the Cave Research Institute CTP, It is very lifelike and has also been highly praised by cultural relics protection units across the country, providing experience for the future production and exhibition of immovable cultural relics according to physical samples. However, the production unit informed that because the resin powder used for printing was purchased abroad, the price was determined by gram. According to the policies and regulations, the price per gram would be dozens of yuan. Finally, the production cost of such a 1-meter-long Buddha statue would be as high as 100000. Such an expensive manufacturing cost may be acceptable for the reproduction of historical relics, and it may also be used for other essential scientific research projects, but it is obviously not the time to apply it to daily production

to sum up, the market publicity about 3D printing has been of positive significance in promoting new technologies for a period of time, but it is a little too urgent to advocate that printing enterprises enter this field now. Not only does this market need to be cultivated, but as long as the production materials rely on imported CD printing, the high product prices will make consumers timid. Therefore, it is fundamental to strengthen the domestic research and development of 3D printing materials and strive to increase the market competitiveness of 3D printing products. Even printing enterprises that have entered this field now can't expect in the short term
