  • MICRODROPLET-BASED THREE-DIMENSIONAL (3D) LASER PRINTING SYSTEM AND METHOD
    Publication number: 20230182200
    Abstract: A microdroplet-based three-dimensional (3D) laser printing system, which includes a laser beam subsystem, a transparent donor substrate, voxel arrays, and the receiver substrate. By irradiating the voxel array with a pulsed laser beam deriving from the laser beam subsystem through the transparent donor substrate, the voxel array is melted and driven away from the transparent donor substrate to generate the ejecting microdroplet array and then deposited onto the receiver substrate. The 3D microstructure is printed in parallel by sequentially irradiating the voxel array and controlling the depositing locations of microdroplet arrays onto the receiver substrate. The system can avoid the satellite microdroplets generating, improve the printing efficiency and resolution, and obtain a wide process window.
