In the domain of photopolymerization-based additive manufacturing (3D vat printing), ceramic photopolymer resins represent a multifaceted composite, predominantly comprising oligomers, fillers, and photoinitiators. However, synergy between fillers polymer matrix, along with stabilization homogenization is facilitated by specific additives, notably surface-active agents, dispersants, adhesion promoters. Although these additives constitute minor fraction in terms volume, their influence on final properties material substantial. Consequently, meticulous selection integration are crucial, subtly guiding performance characteristics resultant matrix composites toward enhancement. This review delves into array dispersants coupling agents utilized components. It elucidates interaction mechanisms examines how interactions affect process. Furthermore, this investigates impact various rheological behavior slurries subsequent effects post-manufacturing stages, such as debinding sintering. also addresses challenges prospects optimization for advanced applications.

The fabrication of high-end ceramics by additive manufacturing gained increasing research interest due to the capacity these techniques break through limitations traditional extractive manufacturing. Although efficient strategies for processing ceramic materials have been shown, with notable examples in dental field, dense glass-ceramics same means is almost unexplored. Herein, a strategy manufacture complex shapes lithium disilicate material extrusion detailed shown first time. An aging behaviour was observed on glass loaded aqueous suspensions and in-deep studied, being related leaching Li+ ions. Based this, hydrogel-based ink high solid content (ϕ≈ 50 vol%), suitable rheological properties (G´≈106 τ ≈1500 Pa) recovery time developed. By using optimized ink, propeller component aspect ratio small internal connected channels, as well crown were successfully printed. A debinding schedule tuned combination differential thermal analysis hot stage microscopy. sintered glass-ceramic parts presented good relative density (≈ 96.7 ± 0.8%) translucency. Outstanding mechanical achieved (Hv ≈5.3 GPa, KIf ≈2.1 MPa.m0.5, σ ≈279 44 MPa), comparable values usually attained powder technology. low deviation flexural strength data reported here absence meaningful defects analysed fracture surfaces homogeneous distribution residual porosity microporous, resulting Weibull characteristic σ0 = 301 MPa. results present work emphasized potential Direct Writing, technique, fabricate geometries, crowns.

Viscoelastic Paste-Based Ceramic vat Photopolymerization: Recent Achievements and Future Developments

Deleted Journal, Год журнала: 2024, Номер 3(1), С. 200111 - 200111

Опубликована: Янв. 21, 2024

Ceramic vat photopolymerization (VPP) enables the fabrication of complex components with excellent properties and high precision. However, compared metals polymers, industrial application ceramic VPPs remains relatively limited. This can be attributed to challenges associated feedstock printability, complexity printing process, insufficient performance evaluation, service verification. To overcome these limitations, design a viscoelastic paste corresponding VPP strategies offer promising solution. paper presents review research on state paste-based VPP. The main technical aspects, including design, support strategies, green-body cleaning, subsequent post-treatment, are discussed. Furthermore, representative applications for various types advanced ceramics surveyed. also highlights involved provides suggestions addressing issues. Finally, future directions promoting additive manufacturing enhanced efficiency reliability
