Abstract

In the past five years solid freeform fabrication of ceramics has generated a great deal of interest as it offers fully automated, rapid, mouldless desktop forming of small ceramic parts. In solid freeform fabrication, 3D computer images of parts generated with CAD software is sliced to produce 2D images and then used to control a fabrication unit which manufactures it layer by layer. In this paper the focus of attention will be continuous ink-jet printing which is a novel solid freeform fabrication method where a ceramic suspension is pressurized and delivered through a fine nozzle and deposited on a substrate according to a pattern generated by a computer. Research into this technique carried out recently is discussed in detail. The development of ceramic suspensions for this process, i.e. materials and properties required, will be analysed. The process, i.e. the use of these suspensions to print monolayers and multilayers of ceramic will be illustrated with several examples. The future potential of the process to micro-engineer components while tailoring the microstructure will be elucidated.
