Embodiment Construction
[0052] An intelligent control method for light intensity in a 3D printer, which adjusts the light uniformity of projection by means of light source circuit partition control and light intensity compensation;
[0053] Among them, the light source circuit partition control method is as follows:
[0054] a. Adjust the light source intensity of all lamp beads to the maximum, and use the sensor to record the light transmission intensity of different areas of the screen;
[0055] b. Use the spline interpolation method to generate a continuously changing light intensity surface, record the light intensity surface information as (x, y, Z), where x, y record the position information of the surface, Z is the value of the surface, traverse the surface, and get Zmin and Zmax, layer Zmin and Zmax to get the layered list zList, traverse the surface again, classify the surface information and push it into zList;
[0056] c. Make a suitable optical path surface according to the layered area ...
