สรุป	Modal analysis is a computational and experimental method for determining the natural frequencies and associated mode shapes of a mechanical structure. By decomposing structural vibration into its fundamental modes (natural oscillation patterns), engineers can predict resonance frequencies, assess dynamic response to external forces, and design structures to avoid problematic vibrations. Developed rigorously by Clough and Penzien in their foundational work on structural dynamics, modal analysis is essential for designing robust mechanical systems.	Additive manufacturing slicing is the computational process of converting a three-dimensional CAD model into a series of two-dimensional cross-sectional layers that are sequentially built up by 3D printing hardware. Developed during the early maturation of stereolithography and selective laser sintering in the 1990s, this method bridges the gap between digital design and physical fabrication, enabling rapid prototyping and production of complex geometries.
