Microstereolithography of Three-Dimensional Polymeric Springs for Vibration Energy Harvesting

Figure 2

Schematic diagram of PμSL system that uses a dynamic mask. A 3D CAD design is sliced into serials of 2D pattern and then displayed as a bitmap image on the dynamic mask. The demagnified image is projected on curable monomer resin surface to define the shape of solidified layers. By sequentially building 2D layers from bottom to the top, complex 3D microstructures are fabricated.
