Quantitative characterization of defects in stereolithographic additive manufactured ceramic using X-ray computed tomography
文献摘要：
Ceramics have been widely fabricated by additive manufacturing(AM).Compared to conventional tech-nologies,the strength of additive manufactured ceramic is relatively low owing to the formation of de-fects during manufacturing process.These defects have significant effects on the microstructure and me-chanical properties of additive manufactured ceramics.However,systematic research on defects,including defect geometrical features,quantitative statistics,and formation mechanism,as well as the intrinsic re-lationship with mechanical properties,need to be studied in depth.In this work,Al2O3 ceramics were prepared from photosensitive slurries with different solid loadings by using stereolithographic(SL)addi-tive manufacturing.The defects,including their sizes and distributions,in both green and sintered bodies were investigated by using scanning electron microscopy(SEM)and X-ray computed tomography(X-CT).Geometrical features and quantitative statistics of the defects were evaluated and discussed to reveal their formation mechanism.Moreover,the intrinsic relationship between defects and mechanical properties of the additive manufactured ceramic was revealed.This study can give some fundamental understanding of the defects in additive manufactured ceramics.
