Bubble growth and ink ejection process of a thermal ink jet printhead

Modelling of additive manufacturing processes: a review and classification

“…Modelling of build time takes place in [142] in which both an analytical and empirical, whereas, in [125] a real coded genetic algorithm is used in order to obtain the optimum solution, concerning the part's deposition orientation, the simultaneous enhancement of its surface finish and the reduction in build time. Finally, in the studies of [147] and [155] heat related KPIs are also modelled utilizing numerical approaches.…”

The electro-adsorption chiller: a miniaturized cooling cycle with applications to micro-electronics

“…are possible with spray jet-injection units, e.g., microelectronic mechanical pumps with explosive boiling pumping action [9,10]. This technology, originally developed for ink-jet printers [11], retains the virtue of no moving parts and should be readily adaptable for use in electro-adsorption chillers (as well as other microcooling devices).…”

Explosive micro-bubble actuator

“…Vapour bubbles generated by a rapid heating of ink in nozzles act as pressure generators [22,23,24]. Small droplets are ejected from the nozzle with a high precision and with frequencies up to 35kHz [25].…”

“…Lin et al [61] were the first to use a heater made of polysilicon and because the development of MEMS technology the effect of a heater with a irregular shape could be measured. Further investigations on the growth and the collapse of bubbles created due to pulse heating by a micrometer sized heater are described in following papers [62,63,64,65,66,23,67,50].…”

“…However, not only pure metals, but also alloys and mixtures of materials can be used. Avedisian et al [60] uses a mixture of Tantalum and Aluminum, the thermal inkjet head used in [23] and [55] has a heater of Hafnium-Bromide. Transparent heaters can be made from indiumtin-oxide [6].…”
