Production method in rehabilitation based on digital molding technology

This project presents the development of an automated workflow for designing custom wrist orthoses using digital molding technologies integrated within Autodesk Fusion 360. TradiWonal orthosis fabricaWon is Wme-consuming and dependent on expert intervenWon. By contrast, this system enables novice users to generate anatomically precise and customizable orthoses from 3D limb scans with minimal input.

Key innovaWons include automated mesh reorientaWon, customizable trimming based on userdefined parameters, and advanced shell generaWon with integrated ergonomic features such as fillets, venWlaWon holes, and mounWng supports. The use of Python scripWng within Fusion 360 significantly reduces manual modeling tasks, ensuring consistency and efficiency.

Validated across 16 representaWve cases, the method proves robust and adaptable for various forearm sizes, orientaWons, and clinical needs. While limitaWons remain in edge smoothing and hole distribuWon due to scan irregulariWes, the system provides a substanWal foundaWon for clinical and industrial applicaWons in rehabilitaWon contexts. Future improvements will aim to enhance geometric robustness and usability for real-world deployment.
