3d-printed hip and pelvis models with human-like skin properties

Overview

This innovative solution leverages advanced multi-material 3D printing technology to develop anatomically accurate hip and pelvis models with integrated soft tissues such as ligaments, muscles, and skin. Traditional models often neglect these elements due to the lack of suitable materials and techniques. By using biomimetic elastomers, these models replicate the elasticity and tactile feedback of human skin, significantly improving realism and expanding their applicability in areas such as biomechanics, surgical simulations, and implant testing.

Technical specifications

• Biomimetic elastomers: Formulated to replicate the properties of human skin and soft tissues, enabling the creation of high-fidelity models.
• 3D printing technology: Utilizes advanced hybrid and modular processes to integrate multiple components including bones, ligaments, muscles, and skin.
• Material library: Includes hydrophilic silicones suitable for micro-extrusion and stereolithography, characterized for printability, elasticity, and durability.
• Chemical crosslinking: Methods developed for robust adhesion between different materials, such as PLA for bones and elastomers for skin.
• Software tools: High-resolution CT/MRI images are converted into detailed 3D models using tools like 3D Slicer and SolidWorks.

Technology readiness level

The technology is currently at TRL 4, with validated processes for printing certain joint components and materials. Future work involves optimizing material selection, developing adhesion strategies, and validating a comprehensive printing process. Further validation will include mechanical and biomechanical testing, surgical simulations, and longevity tests.
