The present application belongs to the technical field of 3D printing, and specifically relates to a printing head wear detection method based on
machine learning, which solves the problems of relying on manual judgment, low detection accuracy, insufficient prediction ability and the like in the prior art. By collecting current, temperature and working
time data, and extracting key features to construct a regression model, real-time evaluation and
remaining life prediction of the printing head wear state are realized. Compared with the traditional method, this method fuses multi-
source data, improves detection accuracy, and can identify wear trends earlier; a weighted calculation method is used to establish a quantitative relationship, enhancing the scientific nature of life prediction; combined with the
control system, automatic warning is realized, reducing unnecessary replacement and sudden
failure risk, thereby improving equipment operation efficiency, reducing maintenance cost, and improving the intelligent level and stability of the 3D printing
system.
