  • 3D PRINTER AND 3D PRINTING METHOD USING CUMULATIVE ILLUMINATION ALONG A SPECIFIC PATH
    Publication number: 20230025234
    Abstract: A 3D printer includes: a tank containing a photocurable resin; a spatial light modulator disposed under the tank and selectively delivering light to a specific region of the photocurable resin, the spatial light modulator including a light source; a positioning stage disposed under the spatial light modulator and moving the spatial light modulator along multiple axes; and a controller controlling the spatial light modulator and the positioning stage, wherein the controller controls the spatial light modulator and the positioning stage such that the spatial light modulator is moved along a specific path and regions of the photocurable resin illuminated with the light partially overlap one another to allow a cumulatively illuminated region to be cured.
