Additive manufacturing (AM) has many advantages over traditional fabrication techniques, especially for manufacturing sophisticated structures with intricate architecture. Most AM techniques however are often limited to single material with homogeneous properties. To incorporate multi-functionality in AM fabricated parts, researchers have recently paid much attention to multi-material AM techniques which allow locally programmed material properties. Challenges still remain to manipulate material during AM process for getting desired functionalities in fabricated parts. In this study, we present a novel magnetic-field-assisted stereolithography (M-SL) AM technique capable of printing particle-polymer composites with graded material distributions. This study characterizes process parameters for particle trace development and establishes the relationship between the process and printed properties.
