Innovative Production of Arm Splinting Mannequin Using 3D Printing Technology and Realistic Silicone-Latex Hybrid Materials

Abstract

This academic article presents new knowledge derived from the development of a high-fidelity medical mannequin designed for practicing Hanging arm cast splinting skills, addressing the challenges of scarcity and the high cost of imported educational media. The primary contribution of this research is the establishment of a 12-step systematic production process that integrates 3D printing technology with the application of a silicone-latex hybrid material to replicate human skin texture and anatomical details with maximum realism. The study demonstrates that the developed innovation achieves high fidelity in terms of proportions, shape, and intricate details, such as palm lines, which are critical factors for accurate clinical positioning. Practical implementation within orthopaedic surgery courses has proven effective in enhancing the proficiency and confidence of medical students. Furthermore, the research identifies methods for material durability enhancement, extending the mannequin's operational lifespan to 1–2 years. This knowledge serves as a cost-effective domestic prototype for medical simulator production, supporting educational sustainability and reducing the risks associated with practicing directly on real patients.
