Structure and Mechanical Properties of 3D-Printed Ceramic Specimens

Resumo

The paper presents the research results of the structure, phase composition and mechanical properties of aluminum oxide ceramic specimens obtained by the additive manufacturing technology. The manufacturing process and the original equipment are described. The formation of several types of pores and surface boundaries between the layers is shown during ceramic 3D printing. It is found that for the different printing strategies, the different mechanical properties are observed in the obtained specimens that are stipulated by the structural anisotropy.
