Direct ink writing (DIW) of structural and functional ceramics: Recent achievements and future challenges

Robocasting of advanced ceramics: ink optimization and protocol to predict the printing parameters - A review

“…The physical features of powders have a vital effect on paste rheology for robocasting. Among others, particle size distribution and shape, powder density and volume fraction are the most significant factors [ 70 , 71 ]. Thus, the control of the ink viscoelastic response requires as a first step a careful selection of powder features.…”

“…More specifically, printing and travel speeds, retraction distance and speed, layer height and filling constitute the cornerstone to successfully robocast a given ink and achieve a targeted resolution. On the other hand, the controlled de-binding stage and sintering phase are necessary to get final printed parts with specific physical, microstructural, and mechanical properties [ 35 , 36 , 37 ].…”

Research progress and applications of silica-based aerogels – a bibliometric analysis

“…DIW needs inks that are non-Newtonian uids, whose viscosity decreases with the shear rate increases. 132,133 In order to obtain SAs, the liquid of 3D printed gels needs to be removed by APD, freeze-drying, or supercritical drying, as discussed above. Zhao et al 25 rst prepared pure 3D printing SAs by DIW.…”

A no-hysteresis TIPS–pentacene:polystyrene blend-based organic field effect transistor by extruded direct ink writing and the application in a resistive load inverter circuit

“…31,32 These advantages of DIW can facilitate the large-scale production of organic electronics through the automation of industrial process. [33][34][35] There are different types of DIW methods, such as the ultrasonically-, pneumatically-, 36 electrohydrodynamically-, 37 and extrusion-based. Compared with other different types of DIW printers, the extrusionbased DIW is easier to use since the driving force is directly provided by a stepping motor, which can also substantially reduce the cost of the printer.…”
