摘要

Digital light processing technique was applied to manufacture alumina ceramic parts with two types of lattice structure units,i.e.vertex interconnect structure and edge structure.The internal porosity of the unit is 40％.The printed parts were sintered and the grain size is about 1.1 μm.The bending strength of the vertex interconnect structure is much larger than that of the edge structure.Materials genome initiative (MGI) aims to digital design and intelligent manufacture for advanced components.This research shows us an example to achieve this goal.
