Abstract

The invention discloses a method for continuously and automatically detecting porosity of a 3D printing sample on a large scale, and provides a method for automatically detecting the porosity of the sample on a large scale at low cost. Based on a microscope detection technology and a stepping motor technology in the current market, a plurality of self-research and development technologies are combined, including an optimized sample preparation device, a simple automatic control device and script-programmed large-batch data processing, so that the purpose of automatic, large-scale and continuous measurement is achieved. Thus, a useful tool is provided for process development of additive manufacturing.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a method for automatic large-scale continuous porosity detection of 3D printed samples. Background technique [0002] In recent years, additive manufacturing technology has become more and more widely used in various industries. With more and more application scenarios, the demand for the diversity of materials and the development of different processes for the same material is becoming stronger. Since the current mainstream method of process parameter development is the statistical DOE method to determine the optimal parameters, and DOE uses a large amount of data, and the acquisition of these data will become a bottleneck that directly restricts the development of DOE process parameters. At present, the primary criterion for judging whether the printing parameters are good or bad is the porosity of the printed product. The detection of porosity mainly includes the following methods...
