The fabrication of high packing density ceramic powder beds for the three dimensional printing process
Three Dimensional Printing is a solid freeform fabrication process which can be used to create parts directly from CAD models. In the past, the 3DP process has been used to create structural ceramic parts using spray dried powders. Although fully dense parts have been made, it has been necessary to …

Design and fabrication of multimaterial electrohydrodynamic-jet deposition system
Electrohydrodynamic jet (E-jet) printing has emerged as a high resolution alternative to other forms of direct solution-based fabrication approaches, such as ink-jet printing. This thesis discusses the design, integration and operation of a unique E-jet printing platform. The uniqueness lies in the …
