Multi-material micro-scale robotic deposition

Three dimensional structures with micro-scale features have found their uses in a number of fields. Hence, there has been a tremendous interest in this field that has led to a surge in the processes capable of producing micro-scale three-dimensional structures. Most of the process developed to date deal with structures made from a single material. In this paper, a novel method of depositing micro-scale three-dimensional structures that can be made of two different materials has been discussed in detail. This process has been made possible by using a 'dual deposition head' that has been developed in house. The results of the process have been shown with the fabrication of multi material functional prototypes that use the dual head setup for fabrication.
