The working principle of 3d printer is similar to traditional printing technology, but in external equipment, 3d model is designed with computer software, and the principle of digital analysis is similar to the experiment of observing tissue slices under medical microscope. When designing a model, it is necessary to use sliced samples, overlap the layers of the designed model, print out the products of the same model, and finally carry out solid modeling. As we all know, the traditional manufacturing technology is to coat ink on paper through inkjet technology, which is also the origin of manufacturing. The biggest difference of 3d printing is that the material it uses is not ink, but a really special material. Of course, due to the limitation of current technology, materials cannot be selected at will, but there are certain types, but there are major breakthroughs.
1. 1 medical treatment
Although the current medical technology can support the normal work of artificial organs, it has high cost, short life and easy infection. But the emergence of 3D printing technology has solved this problem well. Taking titanium alloy as raw material, after organ repair by 1: 1, the shape and function of human organs can be simulated to the maximum extent. Of course, the design of the model is also very complicated, which requires a lot of accurate calculations to discuss the enforceability of specific operations and finally replace organs. As we all know, printing 3d can reduce the substance to the molecular level, and this kind of capsule or solid particle medicine is composed of molecules, so this technology can be used to print drugs, which not only saves time, but also saves drugs that are still in the experimental stage in clinic. It can not only store drug data according to clinical response, but also adjust molecular structure according to clinical response.
2. Road transportation.
The application of 3d printing technology in expressway has been proved to be feasible abroad. By using 3d printing technology, designing road model in CAD software and adding raw materials, the expressway can be printed directly. Although this kind of printer is used in large machinery, its working principle is the same. In addition, in highway maintenance, it is more convenient and faster to use 3d printing technology. The current construction technology is on-site construction. This method is time-consuming and influenced by external factors, such as terrain and weather. If three-dimensional printing technology is adopted, construction can be carried out abroad, such as bridges and subgrade. After the product is molded, it can be said that the operation is simpler, safer and more flexible.
3. Space
3d printing technology plays an important role in the aerospace field. As we all know, aircraft parts are very precise, and there is no error in theory, but it is inevitable that unqualified products will appear on the production line.
You can try to avoid this situation by using 3d printing technology. The raw materials are dissolved in the nozzle. A dedicated software generation model is generated from the 3d model and sent to the receiving device of the printer. The nozzle runs, accumulates and covers according to the predetermined track, and finally forms qualified parts. Modular production can be realized by using large 3d printers, which saves resources and has high efficiency.
Future development trend
At present, domestic manufacturing industry relies on traditional manufacturing industry, and 3d printing technology has not yet formed a scale, not to mention the industrial chain. However, in the future, 3D printing will replace the traditional manufacturing industry, and the application of 3D printing will be more and more extensive. The above application fields are only a typical aspect, others such as art design, building sand table design, parts manufacturing and so on. Three-dimensional printing permeates all walks of life and becomes a trend. This is closely related to our production and life, and it can also be popularized by the people of the whole country. The number of people using 3D printing technology is increasing. With the deepening of application, the application of new technologies is also in the opposite direction, which has improved the level of the whole industry and finally formed a perfect industrial chain. However, there are many problems in the current 3D printing technology. The selectivity of 3d printing materials is poor. Only special materials can be dissolved and recycled at high temperature. In a sense, the scalability and plasticity of the model will be affected. In addition, it takes a long time to print some complex and precise models due to the limitation of materials and computer operation speed. Constantly study new materials suitable for existing technology and innovate printing technology. Simply put, constantly improve the user experience. Technicians can develop and study three-dimensional printing technology from these two aspects.
The emergence of 3d printing technology has filled the gap in manufacturing industry and impacted the traditional manufacturing industry. With its advantages of strong operability, convenience and practicality, and saving resources, 3D printing technology has occupied an unshakable position and achieved cross-industry and multi-disciplinary penetration. In the future, 3D printing will penetrate into every corner of our lives. Now, improving the user experience and improving the existing technical barriers to the maximum extent are all problems that technicians need to solve. After solving these problems, the use and prospect of 3d printers will be further expanded and improved.
