Fig. 20. Incorporating dry powder printing with laser sintering and binder jetting systems Material jetting systems are currently used mostly for polymer jetting so that there is a limitation on the number of materials since only jettable polymers that have good flowability at restricted temperatures can be used. In particular, processes such as Objet’s polyjet technology has inherent limitations on the selection of base materials since the jetted liquid needs to have certain properties of viscosity and curing temperatures in order to be jetted. However, the resolution of the process should be improved to expand its range of applications. More emphasis should be placed on the development of inkjet printing systems which are able to produce high-quality true 3D multiple material components from functional materials, such as metals, ceramics, and smart materials so as to be able to achieve the required thermal, mechanical, and electrical properties for the MEMS/MOEMS industry. The applications of inkjet printing in multiple materials fabrication will expand with the emergence of new jetting techniques such as electrostatic and with better understanding of the process and the utilization of efficient modelling techniques. Future work may focus on the
