Abstract

Multi-Photon Polymerization (MPP) is a powerful technique to fabricate complex micro-scale 3D structures using ultra-short laser pulses. Typically, MPP has been used to manufacture micron-scale components in photopolymer materials. However, the development of micron scale processes that can produce components from multiple materials within a single manufacturing step would be advantageous including the potential to include micro beads that are manipulated and embedded within structures with sub-micron feature sizes. To achieve this, an MPP system was combined with an optical trapping (OT) setup to independently manipulate microparticles in the x, y and z planes. Using OT, particles were transported into the polymerization area of the MPP and encapsulated using a single burst of the MPP laser that solidified the polymer surrounding the particle. In this paper, it will be shown that combining the OT capabilities with an additive manufacturing technique enables the production of
complex multimaterial artifacts.
