Problems solved by technology

[0004] The products printed by biological 3D printers have high precision, and it is difficult to distinguish the small differences of the samples with the naked eye. Generally, high-power microscopes or even electron microscopes are used to observe, but the images are two-dimensional and have no height information.

Abstract

The invention provides a biological 3D printing device capable of realizing online detection and real-time deviation correction and a method thereof, which can be used to detect a three-dimensional solid model of biological 3D printing. The device can detect the measured model in real time during the printing process, process the measured data in real time, and feed back the data processing results to the controller. The controller responds quickly and sends out control commands, thereby realizing online deviation correction and online adjustment of parameters . The online detection device of the present invention includes: biological 3D motion system, optical scanning probe, data collection module, three-dimensional modeling module and host computer; described biological 3D motion system includes XYZ three-axis motion system, driver and main controller, the main The controller is connected with the upper computer. The invention also provides a three-dimensional modeling method based on point coordinate data. After real-time deviation correction, the actual printed 3D entity is as close as possible to the design entity.

Description

technical field [0001] The invention relates to the technical field of biological 3D printing online detection, in particular to a biological 3D printing device and method thereof capable of realizing online detection and real-time deviation correction. Background technique [0002] In order to ensure the quality and economic benefits of products, advanced control and optimal control have been applied to industrial processes. However, whether it is in the application of advanced control strategies or in the process of direct control of product quality, one of the most difficult problems is the difficulty of online real-time measurement of product quality variables. Due to technological, technical or economic limitations, some important process parameters and quality indicators are difficult or even impossible to detect online through hardware sensors. At present, the method of regular off-line analysis is usually used in the production process, that is, sampling is done eve...
