One of the major goals of this research is to develop a seamless, desktop, intelligent, computer-aided design environment to fabricate functional parts using a multi-material fused deposition manufacturing machine. The current research project has already developed tools for multi-material toolpath and virtual simulation of a layered fabrication (3,4). A three-dimensional video microscopy is used to collect experimental data. The parts are fabricated using PZT, PMN-PT, silicone nitride and metals. Design of Experiment, DOE is being performed to quantify and predict void creation and elimination. Using our approach, a designer now could design, fabricate and verify the goals and alter both computation and fabrication parameters quickly. The design cycle has the potential to become faster and more creative.
