As the world's high-tech revolution has swept the world, more and more large groups and companies have begun to engage in the field of 3D printing, which has promoted the rapid development of the entire industry. 3D printing technology has become one of the most profitable areas. Today's 3D printing technology is changing with each passing day, but many have not yet been tested by the market and people are not familiar with it. Today, Xiao Bian has come to us for the popularization of these "novelty" new 3D printing technologies and their development.
In the field of non-metal 3D printing and forming, 3D printing technology based on the principle of jet printing (typically 3DP) and photo-curing surface forming (typically CLIP) will become the absolute mainstream. The reason is simple, CLIP is the fastest 3D printing technology, and inkjet printing is the only printable full-color 3D printing technology that can print large size, fast (close to the surface forming), high strength, and at the same level Form different materials.
In the metal 3D printing industrial application field, the composite forming technology combined with numerical control processing will gradually dominate the market. Of course, there is a premise that Xjet technology cannot be commercialized. Once the Xjet technology could print high-density metal parts and commercialize them, the revolution in 3D printing for the manufacturing industry began.
In the field of biomedicine, printed metal implants will gradually be certified and actually applied to the clinic. The application of biodegradable material implants will follow. As for the active organs 3D printing, I have no confidence in myself. I don’t Think you can live that day.
In order to see more clearly, let us now briefly review the development of 3D printing technology.
3D printing technology has been called rapid prototyping technology in the past. After experiencing the sudden outbreak of the industry in 2012, the people gradually adopted the term “3D printing†to represent this industry, although many older experts in the academic field believe that the term is inaccurate. Therefore, the term "additive manufacturing" is generally used in formal settings. In its nearly 30 years of development, the first 20 years have been upgraded with the traditional 5 types of technologies (FDM, SLS, SLA, LOM, and 3DP) as the core, followed by the emergence of metal 3D printers (SLM), and in the past 5 years, As new technologies emerge one after another, the entire industry has reached a fiery level. Although media and investment institutions in the market have gradually become more rational about 3D printing technology, the development of new technologies has reached a historical high.
The original 3D printing technology was rapid prototyping technology. Therefore, the manufactured parts were all prototype parts and they were “models†and did not have the real function of the products. Therefore, the additive manufacturing technology (typical technology LENS) originally in the field of welding technology is not a "prototype" printer, and it is not a rapid prototype technology. Prior to 2005, the main rapid prototype technology R&D team in China consisted of three companies (Wuhan Binhu Electromechanical, Shaanxi Hengtong, and Beijing Yinhua) and a handful of companies in three universities (Huazhong University of Science and Technology, Tsinghua University, and Xi'an Jiaotong University). The companies (Beijing Longyuan, Shanghai Luen Thai, etc.) and foreign companies entering China are also a few companies of 3Dsystems, stratasys and EOS.
After the advent of the metal 3D printer (SLM), 3D printers began to gradually transition from "rapid prototyping" to "rapid manufacturing." Wuhan Binhu Electromechanical also explicitly proposed the technological development direction of “direct manufacturing function parts†at that time, increased the R&D intensity of SLS manufacturing nylon functional parts and developed the metal forming SLM technology, which also made Binhu Machinery and Electronics the first batch of nylon parts in China. And metal printer manufacturers. From 2005 Israel objet company began to enter China. Its fast and economical characteristics greatly impacted China's "prototype" manufacturing application represented by SLA technology. This situation has been particularly obvious since 2008, and some companies have achieved remarkable results. Impact, and some people even think that the rapid prototyping industry is not working. Since Wuhan Binhu Electromechanical's core products are SLS technology and SLM technology, performance has been steadily rising.
In 2012, under the urging of countries such as Europe and the United States, the 3D printing industry suddenly broke out. The government, media, brokers and even ordinary people began to pay full attention to 3D printing technology. Some people think that 3D printing is a universal manufacturing technology and additive manufacturing in the field of welding. Technology has also been added to the 3D printing industry. The 3D printing market in China has also grown at a geometrical rate. Almost all 3D printing companies have erupted again. Any company that is affiliated with the 3D printing industry has also profited, causing many companies to rely on it. On 3D printing, some obvious two-dimensional forming technologies are also called with 3D printing, and the entire industry is in a “fever†state. On the bright side, the fiery environment has stimulated the emergence of many emerging technologies. New technologies and new enterprises are emerging, such as ordinary paper full-color 3D printers, composite metal 3D printers, architectural 3D printers, chocolate 3D printers, CLIP technology, Xjet technology, liquid metal 3D printers and more.
Two years ago, under the call of some experts, many people began to think calmly about the 3D printing industry. People began to discover that the current 3D printing technology has many shortcomings and it is difficult for them to meet the requirements of the manufacturing industry. In the next two or three years, industry reshuffling may be unavoidable. Some old technologies will also gradually fade out of the market.
Let's explain the reason why I have predicted the development of the industry technology.
Take a look at the main plastic forming industry. The traditional forming methods are mainly injection molding and CNC machining. The requirements for products are mainly reflected in strength, speed, and economy.
The most notable feature of CLIP technology is its fastness. Since solving the core problem of solidification and glass peeling, any additive forming technique cannot be faster than it. As the saying goes, martial arts is not broken in the world, and the speed of parts can be enough to make engineers and designers excited. Another point is that the technology can use ordinary projection technology, the hardware cost of the equipment is low, indicating that the technology product has enough room for price reduction, depending on whether the enterprise is willing or not. Of course, CLIP technology also has the disadvantage that it cannot form full-color parts, and the forming size is not large in the short term.
The 3D printing technology (hereinafter abbreviated as 3DP) has several typical features: high speed, full-color printing, large forming dimensions, etc. The early 3DP technology mainly used gypsum materials to print, which resulted in low strength of parts. Shortcomings. However, the new 3DP technology not only has high forming strength, but also has many forming materials such as nylon, ceramics, and coated sand. If 3DP technology solves the problem of surface quality, its application prospects will be very considerable.
It can be foreseen that once the new 3DP and CLIP technologies are widely used, the traditional non-metal 3D printing technology will be impacted and even eliminated.
For metal 3D printing industrial applications, if the metal 3D printer can not solve the shortcomings of low surface quality, low forming efficiency and high cost, it can only be a complex part in industrial applications, and many complex parts can not be removed due to support can not Processing, so the application of traditional metal 3D printing technology in the industrial field must be limited. The composite forming metal 3D printer that has appeared in recent years combined with numerical control processing has solved the problem of surface quality very well, and its application field has expanded a lot, even can be applied to the mold processing field to become a mold processing equipment.
The emergence of Xjet technology is the revolutionary technology of metal forming 3D printers. I personally amazed the achievements of this technology. Since Xjet technology has not yet been commercialized, what I cannot be sure about is how the technology will affect the density of formed parts. However, from the point of view of introduction, it has almost solved all the shortcomings of the metal forming 3D printing technology. If the technology can solve the density problem, 3D printing can have a revolutionary impact on the manufacturing industry.
The biomedical field is a special field. Almost every "product" is personalized, and does not require extremely high surface quality and high density. It is a field that is particularly suitable for 3D printing technology. For example, some disadvantages of metal 3D printing in the industrial field have advantages in application to the biomedical field. For example, spatial gridding and rough surfaces are more in line with the requirements of biological tissue growth. Therefore, 3D printing technology will have a vast space in the biomedical field after medical approval. However, I always hold a prudent view on the use of active organs for 3D printing. The reason is very simple. I think human studies of some active organs are not thorough enough. There are many unknown knowledge that our scientists have not yet mastered. In this case, the active organs we print must be only "products" with a certain function, not real organs.
We can imagine the scenarios after the above-mentioned several technologies have achieved general commercialization, and we can analyze which technologies may be affected by the impact and even decline.
3D printing technology itself is entrusted with the task of “leading to the manufacturing revolutionâ€, but the traditional 3D printing technology obviously cannot bear such a heavy responsibility. As a company engaged in 3D printing, it is necessary to analyze the market in a pragmatic manner, develop new 3D printing technologies that meet the requirements of future manufacturing, develop new materials in combination with new technologies and new processes, and expand the application market so as to maintain the sustainable development of the company.
3D printing technology gradually matures from the development of the manufacturing industry will benefit from
The development of science and technology has made everything possible. After the advent of 3D printing technology, it was quickly used in various fields. From food production to biomedicine to metal manufacturing, 3D printing technology is now a new breakthrough in the industry.
