Abstract—With the development of and demand for medical technology, the tissue engineering is attracting increasing attention. The traditional scaffold are usually made of metal materials, but more and more metal ions precipitate out as the inserting time increases. Therefore, there have been many researches on the manufacturing of scaffolds with ceramic materials in recent years. This research studies the process of manufacturing an Al2O3 ceramic scaffold with through-hole structure using 3D printing and SOL-GEL technology. And it uses Al2O3 ceramic powders in 2 different grain diameters to improve the scaffolds mechanical properties. The research results show the scaffolds compressive strength, bending strength and porosity are 155.22 Mpa, 35.71 Mpa and 47.24 % respectively when the powders in grain diameters 5 μm and 1 μm are mixed in the ratio 7:3 and under heat treatment at the temperature of 1500 ℃. Based on the material proportion and heat treatment temperature, the Al2O3 ceramic scaffold with through-hole structure is prepared. In the future, this research can further conduct cell culture and animal experiments to test its possibility of being applied to the tissue engineering.
