Problems solved by technology

However, the disadvantage of this existing technology is that it still cannot achieve both resolution and efficiency, and even if the edge of the printed shape is precisely processed, it still cannot solve the problem of broken droplets in the process of microdroplet printing structure.

Abstract

The present invention provides a microdrop three-dimensional printing system driven by pulsed laser, including: a beam subsystem, a support medium, a segmented film array, a droplet array and a receiving substrate, and the pulse laser is irradiated to the support medium through the beam subsystem On the block film array on the surface, the pulsed laser drives the melted or unmelted block film array to fly away from the surface of the support medium, forming a flying droplet array and depositing it on the receiving substrate; by continuously irradiating the block film array, the control An array of microdroplets is deposited onto a receiving substrate at the landing position and a three-dimensional microstructure is printed in parallel. The invention can avoid broken liquid droplets in the process of laser-driven droplet printing structure, can effectively expand the range of printing process window, and can effectively improve printing efficiency.

Description

technical field [0001] The present invention relates to the technical field of laser micro-nano additive manufacturing, in particular to a microdrop three-dimensional printing system and method based on pulsed laser drive. Background technique [0002] Laser induced transfer, based on the high controllability of pulsed laser time and space, utilizes the mechanothermal effect produced by pulsed laser irradiation on the surface of the supporting medium to drive the film away and deposit it on the receiving substrate to form a three-dimensional microstructure. It is a micro-nano additive manufacturing process with no nozzle, high material adaptability and high resolution. It has incomparable advantages in 3D microstructure printing of opaque materials. [0003] Obtaining smaller and more stable droplets is the key to high-resolution printing of three-dimensional microstructures, and the diameter of the droplets is determined by the thickness of the film and the size of the lase...
