Digital light processing 3D printing of surface-oxidized Si₃N₄ coated by silane coupling agent

Recent advances in the application and biological mechanism of silicon nitride osteogenic properties: a review

“…[37][38][39][40] Correspondingly, this method has now been applied to the preparation of bulk silicon nitride. [41][42][43] Silicon nitride scaffolds produced through indirect 3D printing exhibited high levels of surface biological activity, protein adsorption, and osteogenic activity. 44 There are several 3D printing technologies used to fabricate silicon nitride: fused deposition modelling (FDM), laminated object manufacturing (LOM), binder jetting (BJ) and digital light processing (DLP).…”

Additive manufacturing of silicon nitride ceramics: A review of advances and perspectives

“…57 The result showed that the dispersion, wettability, and curing thickness of Si 3 N 4 slurry were all improved by adding suitable silane coupling agents. Yang et al 58 first oxidized the Si 3 N 4 powder and then modified the oxidized powder with the silane coupling agent. The oxidation process could effectively raise the curing thickness and stability of Si 3 N 4 slurry.…”

“…Fortunately, the research on the AM of Si 3 N 4 ceramic has received more and more attentions recently, and attempts have been on the rise. AM technologies of Si 3 N 4 ceramics mainly include (1) powder bed fusion (including selective laser sintering [SLS], and selective laser melting [SLM], [43][44][45][46][47][48][49] and so on), ( 2) photopolymerization (usually including stereolithography apparatus [SLA], 50 laser-induced slip [LIS] casting, 51 digital light processing [DLP], [52][53][54][55][56][57][58][59][60][61][62][63][64][65] liquid crystal display [LCD], 66,67 and so on);…”

Influence of Si 3 N 4 fillers and pyrolysis profile on the microstructure of additively manufactured silicon carbonitride ceramics derived from polyvinylsilazane

“…The low cure depth can also make the printing of geometries with fine details less feasible. Surface modification and intentional oxidation of the particles to change the refractive index and particle size control were demonstrated as efficient methods to adjust the cure depth [ 32–34 ] as well as viscosity [ 34 ]. There have been some efforts to produce particle-filled SiCN (and derivatives) PDCs with stereolithographic methods.…”
