Abstract

A manufacturing method for ceramics with complex structure by laser 3D printing, includes acquiring a three-dimensional model of a complex component to be fabricated, and devising a laser scanning path; placing a substrate in a gas-phase reactor chamber, followed by vacuuming and aerating vapor mixture of gas-phase precursors and carrier gas into the gas-phase reactor chamber; preheating the substrate to a specified temperature, turning on a laser and a thermal imager, the thermal imager controlling laser power in real time by generating a two-dimensional temperature map of a laser spot to realize temperature control a the printing process; setting a distance between the flat-field focusing lens and the substrate and a laser scanning speed; after stacking another one of the ceramic sheets repeatedly, until completing a fabrication of a ceramic complex component.
