Embodiment 1

[0038] Such as figure 1 As shown, a multi-beam laser interference cross-scale 3D printing system of the present invention includes: an image acquisition data processing module 1, a PC control center 2, a laser 3, a spectroscopic system 4, a three-dimensional printing platform 5, printing materials 6, and CCD microscopic imaging System 7. Firstly, the image acquisition data processing module 1 generates layers of physical models after 3D scanning of the printed objects, and transmits them to the PC control center 2; according to the size requirements of the printed nano-patterns, the PC control center 2 simulates the physical model of the 3D nano-pattern structure and sets up the spectroscopic system 4 parameters, so that the beam splitting system 4 divides the single laser beam output by the laser 3 into multiple beams of coherent light, and sets the incident angle and spatial angle of each coherent beam, and the polarization states of each coherent light are consistent. Mult...
