3D printing technology is a high-tech technology at the forefront of science and technology. With the improvement of related processes and the continuous optimization of professional equipment, 3D printing technology, including micro nano 3D printing, is gradually applied to all aspects of life. 3D printing market has huge potential and is bound to become one of the breakthrough skills in the future manufacturing industry.
Micro nano 3D printing is widely used in medical, education and scientific research. For example, the endoscope used in the industry and medical industry was manufactured by CNC or injection molding, with a long processing cycle and complex processing technology, which greatly hindered the development process of the endoscope of manufacturers who started late. At the same time, the existing technical barriers related to the development of endoscopes are high, and it is difficult to break through technical problems, which is also an important factor hindering the development of the domestic endoscope industry.
3D printing technology has been applied in the production and manufacturing of endoscopes since its appearance. However, in the past, 3D printing technology had various shortcomings. First, it was unable to meet the processing accuracy of the endoscope products. Because of the low printing accuracy, the produced endoscopes showed poor quality and often required complex secondary processing; In addition, the previous 3D printing technology can use only a few kinds of materials, which are often not suitable for medical use or special working environments. However, the use of 3D printing technology to produce endoscopes can effectively solve the problem of complex structure of endoscopes, which is difficult to use traditional processing technology to produce. It is a feasible solution to realize the manufacture of endoscopes.

Micro nano 3D printing technology came into being, effectively solving the problems of low 3D printing accuracy and limited printing materials in the past. Micro nano 3D printing technology can improve the printing accuracy up to 2 μ m. To meet the design needs of the complicated and special structural features of the endoscope, the relevant R&D personnel can further design the structure and function in the small pipe diameter space, eliminating the problem that the previous design is useless but difficult to manufacture. In addition, micro nano 3D printing technology can use more printing materials to meet the needs of different use scenarios. Printing materials such as medical endoscopes, industrial endoscopes, biocompatible resins, high hardness hard resins, and super toughness resins can be used in the 3D printing process of endoscopes.
Endoscopes produced by micro nano 3D printing technology have a wall thickness of only 70 μ m. Pipe diameter is only 1 μ m. In addition to ensuring its tiny structure size, it also has highly accurate geometric shape and high-quality pipe surface. The one-step forming of endoscope processing eliminates the traditional complex processing assembly process, which not only saves costs, but also greatly shortens the product development cycle.
In the future, with the continuous progress of micro nano 3D printing technology, it will be used more widely. The development of science and technology is always unexpected. Of course, 3D printing may not have the same far-reaching impact on human society as PC, but it does have the potential to transform the manufacturing industry and even the consumption mode.
