With the development of technology, 3D printing has been widely used in various industries, from industrial manufacturing to various product prototypes, concept design, mold manufacturing, etc.; in the aerospace, defense and military industry to achieve replication, size The manufacture of subtle special parts; the creation of artificial bones and even organs in biomedical applications. The development and application of 3D printing technology has enabled more and more industries to crack the various problems of the industry and create products that could not be realized before.
With the growth of 3D technology, there are also applications for materials. According to incomplete statistics, there are currently more than 200 types of 3D printed materials. If classified, it can be divided into: polymer materials, engineering plastic materials, and biological materials. , metal materials, ceramic materials and other major categories. Among them, the most familiar ones are all kinds of engineering plastics and resins.
Due to the wide variety of resins and various forms such as transparent and semi-fluid, they are widely used in 3D printing of various intermediate design morphology models. The common plastics used in 3D printing are: ABS, PA, PC, PPSF, PEEK and other engineering plastics.
In addition to the engineering plastics described above, PLA can also be used as a printing material in 3D printing. These materials are biodegradable plastics, which are more environmentally friendly than some of the above materials and are generally used in the manufacture of various medical devices.
