Problems solved by technology

[0003] 3D printing technology is also widely used in the field of medical technology. For example, through 3D printing technology, acetabular bone can be printed, and patients can be repaired and treated through medical technical means. When 3D printing technology is used in the medical field, a 3D printer is required. At this time, the combination of 3D printing and acetabular bone is required. However, some current 3D printers can only print in the X-axis and Z-axis directions, and rarely can print in the X-axis and Y-axis directions. Synchronous or asynchronous movement modes in the three dimensions of the axis and the Z axis. For this reason, a method for acetabular bone defect reconstruction is proposed

technical field [0001] The invention relates to the technical field of 3D printing of acetabular bone, in particular to a method for reconstruction of acetabular bone defect. Background technique [0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that builds objects by layer-by-layer printing based on digital model files and using adhesive materials such as powdered metal or plastic. . [0003] 3D printing technology is also widely used in the field of medical technology. For example, 3D printing technology is used to print acetabular bones, and through medical technical means, patients can be repaired and treated. When 3D printing technology is used in the medical field, it is necessary to use 3D printers. At this time, a method of combining 3D printing with acetabular bone is required, and some current 3D printers can only print in the X-axis and Z-axis directions, and rarely can achieve the X-axis, Y-a...
