3D Ink Jet Printing of Ceramics and Biomaterials
Abstract:Ink jet provides a versatile technique for the positioning of precise volumes of fluid. This can be used as a micromanufacturing tool, if the required materials can be delivered in liquid form. We have developed highly concentrated particle suspensions of a range of sub-micron ceramic materials with viscosities sufficiently low for use in commercial industrial ink jet printers. By choosing a suitable strategy to solidify the slurries, 3-dimensional structures can be produced by overprinting. The influennce of fluid properties on printing characteristics will be discussed and example ceramic structures printed and sintered will be described.
It is also possible to use the methods developed for printing inorganic suspensions to print concentrated suspensions of living cells. Preliminary results will be presented of work using ink-jet printing to manufacture 3-dimensional cellular constructs for bioreactor and tissue engineering applications.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
