Formation and Modeling of Droplet Ejection for Electrohydrodynamic Inkjet Printing

Choi, J., Lee, S., Son, S.U., Sungkyunkwan University, KR

EHD(Electrohydrodynamic) inkjet printing based on electrospray and EHD discharging for tiny droplet/jet is known to be able to generate higher resolution and higher aspect ratio of patterns than the conventional inkjet printing(Lee, 2014). EHD inkjet [...]

Inkjet Printing of High Index Zirconia Nanocomposite Materials

Guschl, P., Healy, M.D., Wang, X., Weinstein, M., Pixelligent Technologies LLC, US

Abstract High refractive index (RI) nanocomposites have properties which surpass traditional polymers while maintaining manufacturability. Nanocrystal-polymer nanocomposites, when inkjet-printed, are useful to many display components and aid the development of next generation displays. This paper [...]

Inkjet printing of carbon nanospheres

Abele, D., Banek, N., LeBlanc, S., Orrill, M., Wagner, M., The George Washington University, US

Proposed applications of drop-on-demand (DOD) inkjet printing extend beyond printing of text and graphics to include rapid manufacturing of thin electrical devices. The most commonly printed electronic materials are silver nanoparticles due to their potentially [...]

Depositing Explosives and Chemical Materials on Relevant Surfaces using Inkjet Technology for Calibration Test Standards

Christesen, S.D., Fountain III, A.W., Green, N., Guicheteau, J.A., Hung, K., Moon, R.P., Tripathi, A., US Army, US

Materials deposited on manmade or natural surfaces are frequently utilized as calibration standards for chemical or explosive detecting systems. The U.S. Army Edgewood Chemical Biological Center (ECBC) has redesigned a standard inkjet printer to be [...]

Repeated Duplication in EHD Line Patterning on a Non-Conductive Substrate Based on Controlling the Polarity of Applied Voltages

Choi, J., Lee, S., Son, S., Sungkyunkwan University, KR

This paper addresses the EHD printing of a high aspect ratio of metal lines as a means of forming a high conductivity of metal lines. As stated earlier, EHD printing is advantageous over conventional inkjet [...]

Bio-ink for inkjet printing of living cells

Beirne, S., Ferris, C.J., Gilmore, K.J., in het Panhuis, M., McCallum, D., Wallace, G.G., ARC Centre of Excellence for Electromaterials Science (ACES), AU

This abstract summarises our recent work on the development of a bio-ink tailored for the controlled deposition of cells by inkjet printing. Direct printing of living cells is an emerging approach to the fabrication of [...]

Bioprinting Technology for Regenerative Medicine Applications

Yoo, J., Wake Forest Institute for Regenerative Medicine, US

Advances in micro- and nano-scale processing technologies have provided various therapeutic opportunities in the field of medicine. While techniques developed for tissue engineering and regenerative medicine applications have had initial successes in building a number [...]

Effects of Poly-(N-vinyl-2-pyrrolidone) Additive on Direct-Inkjet-Printed Silver Nitrate Conductive Lines

Feng, P.H., Hwang, W-S, Liu, Y-F, Tsai, H.L., National Cheng Kung University, TW

All-printed electronics has attracted attention due to their fast processing and low cost. Inkjet printing allows circuit components to be directly drawn at a specific area in one step. The printed patterns can be used [...]

Gravimetric calibration for optical measurements of droplets-in-flight

Verkouteren, J.R., Verkouteren, R.M., Zeissler, C.J., National Institute of Standards and Technology, US

We report gravimetric measurements of droplets, traceable to the SI, that enable the correction and calibration of optical measurements routinely used to monitor and control the dispensing of droplets from inkjet printers. This innovation results [...]

Segmented inkjet print head experiment

Einat, M., Ariel University Center of Samaria, IL

Inkjet print heads are commonly designed as a device having single ink reservoir distributed to all the nozzles of the same ink. For limited number of nozzles and head size this solution works well, but [...]
