摘要: Honeycomb sandwich structures were widely used in lightweight design. However, the difficulties with fabrication process actually highly limit their practical usage, especially for ceramic materials. In this paper, 3 mol% yttria-stabilized ZrO2 (3Y-TZP) honeycomb square and hexagonal cell prepared successfully by using digital light processing (DLP) printing method. With a base material density of >6.02g/cm3, square/hexagonal structural 42.89%-66.24% achieved modifying unit wall thickness. It can be concluded that is preferred getting higher bending strength at same density.
