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.
