AI Technical Summary

Technical Problem

In existing photopolymerization printing technology, the fixed or simply scaled settings of the initial demolding speed and reflow waiting time lead to a high printing failure rate. The technology cannot be dynamically optimized according to the actual geometry, which affects the printing success rate and efficiency.

Method used

By acquiring images of the layer to be printed, multidimensional geometric features such as equivalent radius, maximum flow distance, compactness, and normalized perimeter are determined. Combined with a preset algorithm, the initial demolding velocity and reflow waiting time are calculated, and the photopolymerization printing parameters are dynamically adjusted.

Benefits of technology

It improves the accuracy and efficiency of photopolymer printing, avoids structural breakage and incomplete resin filling caused by parameter mismatch, and increases the printing success rate.

Abstract

This application provides a photopolymerization printing method, apparatus, electronic device, and storage medium. The method includes: acquiring an image of a layer to be printed on a target object; determining multi-dimensional geometric features corresponding to the layer to be printed based on the image; the multi-dimensional geometric features include: equivalent radius, maximum flow distance, compactness, and normalized perimeter; calculating the initial demolding velocity and reflow waiting time corresponding to the layer to be printed based on the multi-dimensional geometric features and a preset algorithm; and performing a photopolymerization printing operation on the layer to be printed based on the initial demolding velocity and the reflow waiting time. This method dynamically calculates the initial demolding velocity and reflow waiting time of the layer to be printed based on its actual geometric shape, thereby improving the efficiency of photopolymerization printing.
