The abbreviation of stereolithography is stereolithography apparatus method. The abbreviation of stereolithography is stereolithography apparatus method. The laser with specific wavelength and intensity is focused on the surface of light-cured material and solidified from point to line and from line to surface to complete the drawing operation of one layer. Then the lifting table moves the height of one layer in the vertical direction, and then solidifies the other layer. Therefore, these layers are superimposed to form a three-dimensional solid.
