A 3D printing system based on multi-axis linkage control and machine vision measurement

Abstract

The invention involves a 3D printing system based on multi -axis linkage control and machine visual measurement, including a rack, a workbench used to place artificial osteogenesis, a printing device set up above the workbench, and the material delivery of the material to transport the printing material.Device, image collection camera, driver mechanisms used to adjust the position of the printing device, and control systems, printing devices, material conveying devices, image acquisition devices, and drivers are connected to the control system.Freedom parallel platform, the driver is the six -axis robotic arm, and the printing device is connected to the six -axis robotic arm.During use, the artificial bone bracket is placed on the six -freedom parallel platform, and the location of the printing device is controlled by the six -axis robotic arm.Precise control to achieve three -dimensional pattern printing on the surface of complicated and fine artificial bone surface and the internal surface of the porous structure.

Description

technical field [0001] The invention relates to a 3D printing system based on multi-axis linkage control and machine vision measurement, which belongs to the field of 3D printing. Background technique [0002] With the improvement of living standards, people pay more attention to health care. However, due to some diseases and traffic accidents, the bones of the human body are severely damaged. Due to the limitation of the technical level, it is difficult to repair at this stage. Many patients lose their ability to take care of themselves, which has a serious impact on the patients and their families. At present, the main methods for the problem of bone defects are autologous tissue transplantation, allogeneic tissue transplantation, and the use of alternative materials for repair. At present, these methods all have major disadvantages, such as two operations, limited amount of bone harvested, disease transmission, and low osteogenic activity. Autologous bone is to obtain s...

Problems solved by technology

[0006] In the current 3D printing device, there are nozzle structures and nozzle driving mechanisms that are relatively complicated, and printing accuracy is difficult to control. For example, the ends of each nozzle in the authorized announcement number CN 103948456 B are on the same plane and move at the same time. Large space, not suitable for 3D printing on the inner surface of porous structure
