Paragraph starter

The creation of patient-specific 3D models for design purposes necessitates a rigorous data transformation workflow. This involves initial segmentation of medical imaging data (e.g., DICOM) to isolate the desired anatomical structures, followed by conversion into a suitable format for 3D printing, such as STL. Subsequent refinement using Computer-Aided Design (CAD) software is critical for ensuring model accuracy, smoothing surfaces, and enabling the design of custom components or prosthetics, ultimately preparing a high-fidelity digital model for physical realization.
