Summary: By comparing doped Al2O3 ceramics with pure Al2O3 ceramics, it was found that doped Al2O3 ceramics had better performance when the layer thickness was 50μm, and adding sintering aids could promote low-temperature sintering and improve the mechanical strength of ceramic cores.

Summary: This study used the binder jetting method to prepare a low-cost high strength soluble ceramic core. By reacting heavy calcium carbonate with nano-ZrO2, CaZrO3 was formed at high temperature, reducing the porosity and increasing the bending strength of the ceramic core. The formed CaZrO3 also provided the ceramic core with certain water resistance.

Summary: In this study, three types of solutions were employed to impregnate ceramics and improve the strength of 3D-printed alumina ceramic cores. The introduction of Si from the impregnation solutions significantly enhanced the room temperature and high temperature flexural strength of the ceramics. Among the solutions, silica sol (SS) solution showed the best performance in enhancing the flexural strength at 1500 celcius.

Summary: This paper presents a new approach to density improvement in ceramic binder jetting additive manufacturing by combining powder bed compaction and nanopowders. Experimental results show that increasing compaction thickness at the same layer thickness leads to higher powder bed and sintered densities, as well as reduced number and size of pores in sintered samples. The highest achieved sintered density in this study matches the highest reported density in the literature on binder jetting of alumina, demonstrating the effectiveness of this new approach.

Summary: This study analyzes the impact of microstructural features on fatigue failure mechanisms in Binder Jet Additive Manufacturing (BJAM) parts. The results show that the porosity lines generated during BJAM process are the main cause of fatigue crack initiation and mechanical variability. The use of Hot Isostatic Pressing (HIP) treatment can reduce porosity and scattering of fatigue life.

Summary: In this study, Ca(OH)2-MgO-SiO2 was introduced as a sintering additive to improve the properties of Al2O3 ceramics during the Binder Jetting (BJ) process. The results show that adding sintering additives can reduce porosity, increase relative density, and improve mechanical strength. The optimum conditions were found to be 30% content of sintering additives and a sintering temperature of 1500 degrees C.
