Xi 'an Hospital uses 3D printing to save the left hand of osteosarcoma patients. How does 3D printing work?

3D printing is to print out a three-dimensional object. This is different from traditional printing, which only prints words and images. 3D printer technology is a production technology, which can easily turn the composition in the computer into reality. 3D printing needs a physical model, that is, virtual modeling, which is sliced by professional software, then printed layer by layer, and then covered by layered printing. So what can 3D printing bring us?

3D printing can save design and manufacturing costs.

As far as traditional production is concerned, the more complex the shape of an object, the higher its production cost. With the application of 3D printers, no matter how complex objects are produced, 3D printers can be easily solved without increasing costs. Therefore, the appearance of 3D printing has completely changed the traditional charging method and the calculation method of production cost. In addition, the design of the article can be modified at will without increasing the cost. This saves a lot of training expenses and adds new equipment. A 3D printer only needs a few design projects and new raw materials.

What are the benefits of 3D printing?

Due to the influence of traditional production technology, design innovation is largely limited. For example, the mold manufacturing machine can only be used to manufacture the shape of mold castings, while the rolling mill can only be used to process assembled parts on the rolling mill. The emergence of 3D printers has gone beyond these limitations: how big your design dream is and how much design space it can give you, which opens the door to innovative design for current designers.

What are the benefits of 3D printing in the medical field?

Before the operation, 3D printing technology can be used to design the model to save the operation time. We will have a better understanding of the disease. During the operation, we can find the parts that need to be dismantled, rebuilt and rebuilt immediately. Surgery is more accurate. Because the operation guide plate printed in 3D is used in the operation, it can be taken out more accurately, and it can be exactly the same. Functional reconstruction can be performed. Patients who use traditional prostheses can face disability and disability, but using 3D printing technology can repair some lost bones, rebuild anatomy and function, and make them no longer disabled and deformed. ?
