“…Fusion of the layers then occurs as some solid particles get dragged with the fluid 38 . However, in relation to the current case, the high density and viscosity of the saturated Li 2 MoO 4 solution has been reported to impede mass transport 34 . Yet the densest microstructure observed in the vicinity of the top and bottom surfaces (Fig.…”

“…The initial solid content was 67.6 vol.% mixed with 32.4 vol.% of water. Through a calculation with Li 2 MoO 4 solubility (44.81 wt.% at 25 °C 33 , meaning 81.2 g per 100 mL of water) and density of Li 2 MoO 4 -water solution (1.4897 g/cm 3 ) 34 , the solid content of the paste converted to 60.0 vol.% with 40.0 vol.% of saturated aqueous solution, respectively. Good flow properties under stress are required for successful extrusion 2 .…”

This paper presents for the first time the fabrication of dielectric ceramic parts by 3D printing without sintering. The printable paste was prepared by mixing a carefully selected amount of water-soluble Li2MoO4 powder with water. A viscous mixture of solid ceramic particles and saturated aqueous phase was formed with a solid content of 60.0 vol.%. Printing of the sample discs was conducted with material extrusion using a low-cost syringe-style 3D printer. The consolidation and densification of the printed parts occurred during both printing and drying of the paste due to extrusion pressure, capillary forces, and recrystallization of the dissolved Li2MoO4. Complete drying of the paste was ensured by heating at 120 °C. The microstructure showed no delamination of the printed layers. Relatively high densities and good dielectric properties were obtained, especially when considering that no sintering and only pressure from the extrusion was employed. This approach is expected to be feasible for similar ceramics and ceramic composites.
