Smart 3D-Printed Insoles for Plantar Fasciitis: A Digital Workflow and Biomechanical Approach
Abstract: Plantar fasciitis is a primary contributor to plantar heel pain, which severely impacts daily mobility, posture, and overall quality of life. Current clinical guidelines emphasize a multimodal rehabilitation strategy where foot orthoses serve as an effective adjunct rather than an isolated treatment. Conventional custom foot orthoses often involve labor-intensive plaster casting, vacuum forming, or thermoforming steps that complicate modifications. This project demonstrates an advanced, digitized workflow utilizing 3D scanning, computer-aided design (CAD), and additive manufacturing to fabricate patient-specific, flexible thermoplastic polyurethane (TPU) insoles. By capturing individual plantar geometry and integrating pressure-mapping evaluations, the proposed method provides precise medial arch support, heel cushioning, and systematic load redistribution. This paper outlines the anatomical background, mechanical principles, detailed digital fabrication methodology, clinical implications, and future directions for 3D-printed orthotic management.
