What Is the Role of Nylon in Additive Manufacturing for Medical Applications?

High Strength and Flexibility for Patient-Specific Devices

Nylon, particularly Nylon PA12, plays a vital role in medical additive manufacturing due to its excellent mechanical properties. Its combination of high tensile strength (~48 MPa), ductility (~20% elongation), and fatigue resistance makes it ideal for patient-specific devices such as prosthetic sockets, orthotic braces, and wearable medical supports that require both strength and flexibility.

Biocompatibility and Sterilizability

Medical-grade nylon materials used in processes like Selective Laser Sintering (SLS) and Multi Jet Fusion (MJF) meet ISO 10993 or USP Class VI biocompatibility standards. They are safe for skin contact and can be sterilized via methods such as ethylene oxide or low-temperature steam, making them suitable for surgical guides, diagnostic equipment housings, and anatomical models used in clinical settings.

Lightweight and Wear-Resistant Components

Nylon’s high strength-to-weight ratio and wear resistance allow for the creation of durable yet lightweight medical tools, such as surgical jigs, instrument holders, and mechanical subassemblies in rehabilitation equipment. It maintains stability under repeated use and mechanical stress, ensuring reliability in hospital and outpatient environments.

Customization and Mass Personalization

Additive manufacturing with nylon enables cost-effective production of fully customized medical devices based on 3D scans or imaging data. This supports tailored solutions in prosthetics, orthotics, and dental applications, enhancing patient comfort and improving treatment outcomes.
