3D printing technology in the medical field application of the four levels of the highest level is metal 3D printing, active cells, proteins and other extracellular matrix, details are as follows:
1, Introduction: the technology of three-dimensional stereo printing. Three-dimensional stereo printer, also known as rapid prototyping printer. It is the use of ordinary printers, the principle of the printer and the computer connected to the raw materials loaded into the body, through the control of the computer, with a laser injector to accumulate the raw materials layer by layer, and finally the blueprint on the computer into a physical object.
2, features: 3D printing technology can be complementary to traditional manufacturing technology, *** with the promotion of modern manufacturing transformation. In addition, 3D printing technology itself is constantly improving, there are constantly new application materials, application areas are gradually expanding.?
3, the principle of 3D printing: three-dimensional printing design process is: first through the computer-aided design or computer animation modeling software modeling, and then will be built into a three-dimensional model "partition" into a layer-by-layer cross-section, so as to guide the printer layer-by-layer printing. The standard file format for collaboration between design software and printers is the STL file format.
4, the printing process: the printer reads the cross-section information in the file, and prints out these sections layer by layer with liquid, powder or sheet material, and then bonds the layers together in various ways to create a solid. This technology is characterized by its ability to create objects of virtually any shape.
