Drop-on-Demand Electrohydrodynamic Jet Printing of Graphene and Its Composite Microelectrode for High Performance Electrochemical Sensing

Droplet generation process can directly affect process regulation and output performance of electrohydrodynamic jet (E-jet) printing in fabricating micro-to-nano scale functional structures. This paper proposes a numerical simulation model for whole process of droplet generation of E-jet printing based on the Taylor-Melcher leaky-dielectric model. The whole process of droplet generation is successfully simulated in one whole cycle, including Taylor cone generation, jet onset, jet break, and jet retraction. The feasibility and accuracy of the numerical simulation model is validated by a 30G stainless nozzle with inner diameter ~160 μm by E-jet printing experiments. Comparing numerical simulations and experimental results, period, velocity magnitude, four steps in an injection cycle, and shape of jet in each step are in good agreement. Further simulations are performed to reveal three design constraints against applied voltage, flow rate, and nozzle diameter, respectively. The established cone-jet numerical simulation model paves the way to investigate influences of process parameters and guide design of printheads for E-jet printing system with high performance in the future.

In this paper, mechanical aspects of magnetic recording technology and nonimpact printing are discussed. In the recording area, theoretical and experimental aspects of air bearing theory, head/disk dynamics, and head/disk tribology are studied. Flutter of rotating disks is investigated, the flow field between rotating disks is described, and nonrepeatable run-out of disk file spindles is studied. Furthermore, the head/disk interface for flexible media is discussed and dimensional stability of flexible substrate is examined. In the printing area, experimental and theoretical investigations using continuous and drop-on-demand fluid jets are presented, and numerical calculations of the drop formation process in drop-on-demand fluid jets are described.

Robust Response

ABSTRACTA piezoelectric drop on demand printer has been used to print primary human osteoblast and bovine chondrocyte cells. After deposition the cells were incubated at 37°C and characterised using optical microscopy, SEM and cell viability assays. Cells showed a robust response to printing exhibiting signs of proliferation and spreading. Increasing the drop velocity results in a reduced cell survival and proliferation rates but both cell types grew to confluence after printing under all conditions studied.

The formulation of a stabilized ceramic ink and the adaptation of a piezoelectric-activated drop- on-demand jet printer with a 65 mm nozzle for the direct solid freeforming of ceramics by multilayer jet printing is reported. The procedure has exciting implications for the miniaturization of ceramic circuits and for the fabrication of solid oxide fuel cells, ordered ceramic composites and small monolithic ceramic components of complex shape.

AbstractA conventional rapid prototyping technology has been used to build prototypes using direct deposition through a drop-on-demand ink-jet printing system. Al2O3 - filled waxes have been developed with viscosity values close to those of the materials used in commercial printing systems. Commercial dispersants based on stearic acid and sterylamine have been studied and stable ceramic suspensions with ceramic volume fractions in the range 20–40 volume% produced with suitable viscosity. A suspension of 20% Al2O3 in an alkane wax has been successfully printed.
