A simple method for judging the quality of stereoscopic grating

Next, super-shadow 3D printing will teach you the key points that need to be paid attention to when distinguishing the quality of grating materials:

1, transparency of grating: people can see it at a glance. If you see that the material is yellow, blue and gray, it means that the transparency of the material is not good;

2. Grating focusing: the accuracy of focusing is related to the problem that the stereoscopic picture produced has good stereoscopic effect and the imaging is not false. You can judge whether the grating is well focused by whether the black line displayed on the test paper is black enough. If the test paper is not black enough and the line image is false, it means that the grating is not focused well.

3. Uniform and stable line spacing: Measuring with test paper is the best method. You can also use two identical gratings to find out whether the overlapped gratings are misaligned after rotating 180 degrees, so as to detect the sector problem in the grating manufacturing process at one time.

4. Good molding: A grating can be identified by observation. By observing the light, we can see whether it is smooth or not. We can also look at the grating through the lamp tube. If there is a rainbow pattern, it means that there is something wrong with the meat cutter that produces the mold.

The above is just a general identification method. In fact, it depends on your use to make the grating material shine to the extreme. The general viewing angle of grating used for three-dimensional design is small, and the viewing angle of grating used for variable painting is large.
