As a representative high-tech, 3D printing technologyhas developed rapidly in recent years. In addition to being widely used in the protection of ancient cultural relics, manufacturing, aerospace and other fields, 3D printing technology is also continuously released in the medical industry. Its own value has unlimited market prospects. The details are as follows:
3D printing is used in customized medical models and surgical guides
Before the operation, perform three-dimensional modeling based on the patient's CT or MRI data, and then print the model through a 3D printer to obtain a medical model. The main function of the 3D printed medical model is to allow the doctor to see the three-dimensional structure of the surgical site before the operation, which helps the doctor plan the surgical plan. Especially for complex surgery, it helps to reduce the risk of surgery and improve the success rate of surgery.
Application of 3D printing in dentistry
The cost of dental restoration and treatment is an important factor that dental clinics and laboratories need to consider. Many prescient dental clinics and laboratories have introduced digital dental technology to improve efficiency and reduce costs. In recent years, dental restorations based on software design have become popular, and digital dental technology combined with 3D printing has brought high precision, low cost, high efficiency, and dental data that conform to the standardized production chain for the dental industry.
Application of 3D printing in medical device manufacturing
Manufacturing medical devices are the same as other products. In the development stage of new products, prototypes need to be manufactured for design verification. The potential of metal 3D printing technology in the field of medical devices has surpassed prototypes to undertake complex surgical device manufacturing tasks. For example, in the knee joint anterior cruciate ligament injury repair operation, the doctor must first remove the remaining anterior cruciate ligament, and then accurately replace the graft ligament. To ensure the accuracy and minimal invasiveness of the operation, doctors need to resort to a sophisticated and special surgical tool. The nickel-chromium-iron alloy used to manufacture this tool is a difficult-to-process material, and it is very difficult to manufacture the surgical tool using traditional machining methods, and it takes a long time and high cost. In this case, the use of metal 3D printing technology for manufacturing is more suitable.
Application of 3D printing in manufacturing medicine
The impact of 3D printing technology on pharmaceuticals is mainly reflected in four aspects: one is to achieve personalized customization of the active ingredients of the drug; the second is to customize the dosage to provide patients with personalized treatment plans. This layer-by-layer printing method allows different coatings to be tightly combined with each other so that the maximum dose of a certain substance can be placed in a tablet so that the patient can swallow a few or smaller tablets; The third is that the shape can be customized. For children who don’t like to take medicine, 3D printing technology is used to print out various interesting shapes to coax the children to take medicine; the fourth is to use 3D printing technology to make the medicine have a special microstructure, improve the release behavior of the medicine, and improve the curative effect and Reduce side effects.
