In the 21st century, there are few technologies that can attract global attention, but 3D printing continues to stimulate people's nerves with its dreamlike magic, causing the world to debate endlessly. 3D printing is about to set off a new era. The theory of revolution has become more and more intense, and it marks the transformation of traditional industries-the transformation of intelligent manufacturing, the transformation of social production.
The application and development of 3D printing in the future will bring about changes in the global structure of the manufacturing industry. Mastering 3D printing technology is undoubtedly occupying an absolute dominant position in a new industrial revolution. So what is 3D printing? This mysterious What incredible functions does modern technology have?
3D printing is also called additive manufacturing. It is based on digital model files to turn a complex three-dimensional part into a two-dimensional problem, and then use a computer to control it, using powdered metals or plastics that can be glued. Composite materials, the technology of constructing objects by printing layer by layer. In fact, in terms of principle, the most common 3D printing in people's lives is Mak Kee's ice cream cone. Jackie Chan's 2012 movie "Zodiac" shows the principles of 3D scanning and 3D printing in a vivid way.
Generally speaking, there are four types of 3d printing:
The first is Selective Laser Melting (SLM, Selective Laser Melting) 3D printing of metal materials.
The second is the selective laser sintering (SLS, Selective Laser Sintering) technology or the multi-jet fusion (MJF, Multi Jet Fusion) 3D printing technology of nylon materials.
The third type is the 3D printing technology of SLA (Stereo Lithography Apparatus) of resin materials.
The fourth type is the FDM (Fused Deposition Modeling) 3D printing technology of plastic materials: it looks the most intuitive, just like building a wall, the materials are melted and piled up one after another.
Innovation is the driving force for social development. The combination of creativity and the right technology can produce new products, leading to an industrial revolution. In all industries, the disruptive technology of 3D printing has come to the forefront. It can create brand-new products and more efficient manufacturing processes. 3D printing technology perfectly meets the requirements of customization and mass production. The representative of "Internet + smart manufacturing", the unlimited creativity of 3D printing has made it widely used in various fields such as jewelry, footwear, construction, automobiles, aviation, and medical care.
In early 2020, the University of California, San Diego used rapid 3D printing technology for the first time to create a spinal cord stent that mimics the structure of the central nervous system, which successfully helped rats restore their motor function. Recently, a US space company announced that they hope to use 3D printing technology to manufacture all the parts of the rocket, and try to reduce the number of parts and improve the reliability of the parts. The company said it plans to launch the first fully 3D printed rocket in 2022.
In the context of this technological wave of 3D printing, 3D printing technology has begun to enter the classroom and has become one of the topics for students to learn, making more people touch on 3D printing technology. At the same time, 3D printing can also make learning and training more lively and interesting, so that children not only enjoy it when learning and training, but also enhance their imagination and increase the cognitive ability of research on the subject.
No matter what the cutting-edge development technology is, the ultimate development trend is sustainable development. The traditional production process will have a certain negative impact on the environment. Therefore, the world focuses on reducing waste gas generation, reducing energy consumption and reducing the carbon footprint of product manufacturing. Therefore, my country's 3D printing technology research and development and industrial development applications Establishing a comprehensive, coordinated, and sustainable principle will truly bring about social change and development. Makes 3D printing protect the ecological environment while improving people's lives, and promote the sustainable development of mankind.
The advancement of science and technology is unstoppable. From the birth of 3D printing technology to everyone's knowledge, it is not difficult to see that this is the affirmative result of technological development and trends. It has brought vitality to the manufacturing industry. In the future, 3D printing will undoubtedly develop more vigorously, bringing a milestone change to the future manufacturing industry on the way of continuous improvement and improvement.
