Abstract
In this study, the volumetric additive manufacturing (VAM) process is examined with a focus on the development of a fabrication device and programming for part production using this method. As an innovative technology, VAM addresses several limitations of other additive manufacturing techniques, such as long production times and the anisotropic properties of fabricated components. This study investigates the role of equipment and the impact of applying filters in various configurations on the final quality of components during the Radon-based image processing and fabrication process. The results indicate that the application of filters significantly improves the quality and dimensional accuracy of the produced components. Additionally, a comprehensive MATLAB-based programming solution has been developed to convert three-dimensional models designed using CAD software into playable videos suitable for VAM-based fabrication. The finalized code integrates a user-friendly graphical interface to enhance accessibility and ease of use. Overall, this approach provides a novel pathway for the rapid and precise fabrication of complex components, enabling efficient production within shorter timeframes.
