AI Technical Summary

Technical Problem

In the prior art, the measurement process of printing compensation parameters is cumbersome and the accuracy is insufficient, resulting in a gap between the actual size and theoretical size of the printed three-dimensional model.

Method used

By designing a prefabricated measuring piece, the measuring piece includes a plurality of measuring parts with different sizes, and the plurality of measuring parts are arranged in sequence in the preset direction. The solid model of the prefabricated measurement part was printed using the liquid photosensitive resin to be tested, and three-dimensional point cloud data scan was performed to determine the actual size of each measurement part, and calculate the size compensation coefficient for dimension compensation.

Benefits of technology

It is possible to obtain accurate printing compensation parameters through a single measurement process, improve measurement efficiency and accuracy, and ensure that the actual size of the printed three-dimensional model meets the theoretical size.
