Abstract Fused deposition is a layered manufacturing technology, which is being investigated for fabrication of functional parts. Defects and voids in the build process affect the quality and level of accuracy of components. These occur due to several factors, such as the toolpath contours in a layer, material(s) deposited, and the environmental conditions. For a functional part to be constructed, a perfect green part is critical. To further understand this process, a visualization of the deposition is needed. Therefore, we have developed a real-time video microscopy system. The hardware has been constructed and mounted on the existing liquefier. Real time deposition of layered manufacturing is being recorded. Three materials being investigated are: PZT, silicon nitride, and wax. The contrast in wax layering is not as strong, which makes visual observation extremely hard. However, interaction between the roads of PZT and silicon nitride parts has been successfully quantified. Using the current set up and software, the road width and height have been quantified. (Auth abstract) [References: 3]
