Transfer Methods toward Additive Manufacturing by Electrophotography
Abstract:3D printing of complex structures by selective deposition is currently dominated by inkjet technologies. Dry toner systems, despite their high productivity and maturity in 2D digital printing, have only been used indirectly for Additive Manufacture of objects above the micro scale. Although electrophotography (EP) promises increased deposition efficiency and a means of utilizing materials not amenable to liquid ink formulations; this potential cannot be achieved using conventional electrostatic transfer methods.
This paper reviews the problems associated with conventional transfer in multilayer printing (including height limitation and defect exaggeration) and demonstrates alternative transfer principles which promise to unlock the potential of Additive Manufacturing by EP.

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.
