“…As it is well known, structural ceramics possess excellent strength and hardness but very poor toughness, hence processing of ceramics can be significantly difficult especially when the details of the components come to microsize . As for conventional shaping methods of low precision such as slip casting, dry pressing, isostatic pressing, extrusion molding, much postprocessing work should be conducted on the as‐shaped components to reach the high precision and surface smoothness .…”

In this study, we have successfully developed a unique 3D printing approach based on mask-image-projection stereolithography (MIP-SL) to fabricate structural ceramics microcomponents with low cost and high efficiency. Ultra-dense submicron crystalline ceramics without fierce grain growth could be obtained via tailoring the sintering kinetics. The ZrO 2 ceramic microcomponents reached the highest relative density (RD) of 99.7% with the average grain size of 0.52 μm upon sintering at 1550°C while the Al 2 O 3 ceramic microcomponents reached its highest RD of 98.31% with the average grain size of 2.6 μm upon sintering at 1600°C.Oxide ceramics microcomponents of fully flexible design can be produced easily without visible defects via the method developed in this study, which demonstrates significant potential in the applications of microelectromechanical systems, micro-optical electronics systems and micro-opto-electro-mechanical systems. The method developed in this study has addressed the problem successfully by healing the interlayer interface defects in densification process via the sintering kinetic window and microstructure evolution. The current work provides a promising opportunity to fabricate structural ceramic microcomponents with complex shape, high precision, and high surface smoothness. K E Y W O R D S

“…However, whilst 3D printing of polymeric and metallic objects is being used, even industrially, for already a decade [7]- [10], the fabrication of 3D printed ceramic parts is still mainly under research level development [11]. Among other, 3D printing technologies including selective laser sintering (SLS) [13], direct [14] and indirect [15] inkjet printing (DIP and IIP) and stereolithography (SLA) [16] have been used so far for the fabrication of functional ceramic devices. In particular, the reader is referred to the review by Ruiz-Morales et al [12] on the most recent developments of 3D printing of ceramics in the field of energy and, more specifically, for Solid Oxide Fuel Cells applications.…”

“…These steps are repeated until the whole green part is eventually produced. In the past years, many kinds of oxide ceramics, including Al 2 O 3, ZrO 2, ZTA, and other oxide ceramics have been widely reported using this method. However, it is noted that all these reported oxide ceramics are in white color.…”

The stereolithography‐based additive manufacturing of white‐colored Al2O3 and ZrO2 ceramics has been widely reported, whereas the stereolithography‐based additive manufacturing of gray‐colored SiC ceramic is very difficult and challenged. In this paper, the reasons for the difficulty which SiC ceramic facing during stereolithography were discussed and compared to Al2O3 and ZrO2 ceramics. The effects of particle size, solid loading, stereolithography parameters, and photoinitiator kind and concentration on the curing ability of SiC slurries were further studied in detail. Finally, complex‐shaped SiC ceramic green parts with high accuracy and high quality were successfully fabricated. This study demonstrated that the stereolithography‐based additive manufacturing had a great possibility for preparing gray‐colored SiC ceramics.
