The difference between 3D printing technology and traditional copiers depends on: firstly, it does not use ink as the raw material like traditional copiers, but only uses powdered or flocculent plastic and its laminated glass, wheat flour, polyester and other chemical substances as the copying raw material. Secondly, 3D printers often become "3D", as their effectiveness is no longer limited to text methods, but can convert virtual 3D graphics in the connected electronic computer into actual products. Therefore, 3D printing is a new technological aspect that belongs to additive manufacturing and rapid prototyping technology. Its key advantages include the ability to carry out production and manufacturing anytime and anywhere, especially when the parts are in large and small quantities, preventing cost extravagance caused by frequent start-up of the production line; The basic principles of 3D printing technology determine that it will not be constrained by product varieties throughout the production and manufacturing process, and can produce products with extremely complex structures. is a traditional mechanical processing and manufacturing method that cannot be maintained; Compared with traditional subtractive manufacturing methods, additive manufacturing reduces the extravagant waste of raw materials, thereby reasonably reducing production costs.


The basic technical concepts of 3D technology can be divided into three processes: the first step is to design a three-dimensional electronic device solid model of the object block to be copied in the electronic computer, including its appearance and each specification. This process can be maintained according to some current drawing software, such as CAD, 3Dmax, etc. Secondly, under the premise of connecting with electronic computers, the 3D copier will divide the created 3D pattern information content layer by layer, and the relative density of the segmentation is related to the copier and its raw materials. Finally, based on the information content of the segmented floor plans, the 3D printer automatically clarifies the relative copying path and copies from top to bottom until the final shape is formed. The method of copying varies depending on the type of equipment, which can be to melt the raw materials through high temperature or laser lamp method, and then deposit them layer by layer into shape; Strong adhesive can also be used to bond the raw materials layer by layer.


In recent years, with the gradual improvement of 3D printing technology, 3D printers have been used in more and more industries, including mechanical equipment manufacturing, microbiological diagnosis and treatment, construction, archaeology, and food enterprises.


1. Mechanical equipment manufacturing industry. With the advent of economic globalization, the demand for goods is becoming increasingly diversified, which has promoted the changes in production methods for multiple types of mass production, and even for the production of individual parts. The advantages of 3D copying technology in copying complex structural parts and low start-up costs have provided opportunities for the development trend of lean production of loose parts.
2. Microbial diagnosis and treatment industry. In recent years, some countries have already used 3D copying technology to produce human organs with no conflicting effects. In addition, the copying of human bones and front teeth has also been maintained, making certain contributions to the development of medicine.
3. Construction industry. At present, the key application of 3D copying technology in the construction industry is for manufacturing models. Architects can create architectural models of their design schemes based on the ultimate display of 3D copiers in one go, and evaluate their relative functions. Compared with other methods of manufacturing models, they have the advantages of fast speed and low production costs. In addition, 3D photocopying technology can also produce houses that can be immediately occupied by people.
4. Archaeology industry. When some ancient artifacts are damaged, such as gaps or gaps, they can be monitored and repaired based on 3D photocopying technology.
5. Food enterprises. At present, the use of 3D copiers to copy simple ingredients, such as pancakes and fruits, is already present in the sales market. This type of technology can not only reduce the workload of manual services, but also make the copied products more detailed in appearance, and the taste is basically no different from general practices.


With the development trend of social development and technological progress, 3D printing will also be highly valued by more and more people. Its technical strength will continue to improve and its role will gradually improve. Its development prospects include the following aspects: ① Diversification of printing raw materials. Raw materials are the foundation of photocopying goods, and the development trend of 3D printing must have the necessary condition of using raw materials with relative characteristics. According to the survey, the current market share of this technology in the processing industry is still very small, and a key reason for this is due to the limitations of the types of copying raw materials. [5] Therefore, in the future, the raw materials for 3D printing will inevitably develop towards a diversified trend, and the research and development of new materials can promote the production and manufacturing of copiers for a large number of goods If the diversification of raw materials is the foundation of the development trend of 3D printing, then the independent innovation and improvement of technology are important for the development trend of 3D printing. This is reflected in the precision, copying speed, type of copied product, and level of intelligent system of the copied product At present, although 3D printing has already been applied in many industries, its application is not widespread or incomplete. For example, only a few types of food production can be applied to 3D copying technology; Its application also has significant limitations in industries such as engineering, construction, and medicine; There are also some manufacturing industries that have not yet entered the technical application of this technology due to various reasons. Therefore, with the rapid development of technological progress, 3D printing will be widely used in various fields in the future, fully exerting its great benefits for a large number of industries The manipulation of printer prices, although compared to traditional methods, 3D printing saves raw materials, reduces production time, and to a certain extent reduces the cost of producing and processing goods. But currently, the price of 3D copiers themselves is quite expensive, especially for copiers with complete functions and high precision regulations, which is very difficult for some small-scale companies. Therefore, with the gradual improvement of technology and raw materials, the production cost of 3D printers themselves will be reduced, making machine equipment no longer a key technical difficulty.
