In this study, we analyze the effect of temperature on the characteristics of post-treatment process of zirconia 3D printing. During the post-treatment process, the debinding and sintering processes were separated to determine the effect of temperature in each process, and the optimized conditions were adopted. The shrinkage rate and weight reduction rate according to the temperature conditions of the post-treatment process were checked, and the change in warpage characteristics and surface precision analysis were performed. In the debinding process, When the peak temperature was low, the warpage characteristics improved and the processing time decreased. Conversely, during the sintering process, when the peak temperature was high, the warpage characteristics improved. The process time and output quality can be improved if the optimized temperature conditions are used in the post-treatment process.

Nanostereolithography induced by a femtosecond laser is widely used for fabrication of three-dimensional (3D) microstructures with submicron resolutions. In this study, we propose a 3D continuous laser scanning method for an effective direct writing of 3D microstructures. The advantages of the 3D continuous laser scanning method are analyzed by considering its high resolution, time economy, and fabrication effectiveness. As the 3D continuous laser scanning is an efficient manufacturing method, which can immediately respond to a complex 3D structure, it could be used for various applications including platforms for cell culture, metamaterials, and functional sensors. In this paper, the 3D open cell structure was fabricated and cells are cultured on the structure for microcell chip application.
