  • Outline of the development and processing steps for 3D printed airway stents.

    • Main Results:

    • 3D printed stents allow for precise patient-specific sizing, minimizing mismatch.
    • Custom stents can reduce high-pressure points on distorted airway anatomy.
    • This approach theoretically reduces stent-related complications like migration and erosion.

    Conclusions:

    • Patient-specific 3D printed airway stents hold promise for improved management of complex airway diseases.
    • This technology offers a more tailored approach to airway stenting.
    • Further research and development are needed to fully realize the potential of 3D printed stents in pulmonology.
