Electrostatically-Injected Droplet (ELID) method took place when high voltage was applied between a capillary tube filled with ion conductive liquid and a metal plate electrode. At the last DF conference, we reported that living cells were printed and demonstrated fabrication of simple 3D structures which contained living cells and scaffolds by the ELID method. However the stiffness of the simple 3D structures were low, it was necessary to print not only line-shaped scaffolds but also sheet-shaped scaffolds. In this paper, we developed new printing machine “Bio-Cell On”. We patterned a precise line and a thin sheet of gelatin with this machine. The width of the line was about several micron meters. It was narrow enough to be used as scaffolds because the diameter of cells was about several 10 micron meters. The thickness of the sheet was controlled by the time and amplitude of voltage application.

  • For more than 25 years, NIP has been the leading forum for discussion of advances and new directions in non-impact and digital printing technologies. A comprehensive, industry-wide conference, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems, including drop-on-demand ink jet, wide format ink jet, desktop and continuous ink jet, toner-based electrophotographic printers, production digital printing systems, and thermal printing systems, as well as the engineering capability, optimization, and science involved in these fields.

    Since 2005, NIP has been held in conjunction with the Digital Fabrication Conference.
