Advanced AI-Powered Inspection for Medical Components: Ensuring Quality in Sintered Coatings and Additive Manufactured Parts

In the medical device industry, quality control is paramount—especially for critical components such as femoral knees, spine implants, acetabular cups, and other parts requiring absolute precision and durability. With advancements in additive manufacturing and sintered coating processes, medical component manufacturers face the unique challenge of inspecting intricate, variable surfaces to ensure structural integrity and quality. LM3 Technologies’ AI-powered vision systems provide an innovative approach to meet these rigorous demands with greater efficiency and reliability.

The Unique Challenges of Sintered Coating Inspection

Sintered coatings are applied to various orthopedic implants to enhance biocompatibility and integrate seamlessly with the human body. However, coating defects such as discoloration, voids, and particle separation can undermine performance and patient safety. Traditional inspection methods can struggle to detect these subtle, complex flaws, often requiring labor-intensive, subjective evaluations.

Using high-resolution imaging and AI-driven models, LM3’s PAQi platform is designed to address these challenges by:

• Capturing detailed images across multiple inspection angles.

• Training custom AI models to detect specific defect types, even on the intricate surface textures common in sintered coatings.

• Providing real-time defect detection, reducing the need for manual inspection and improving throughput.

Precision for Additive Manufacturing Components

Additive manufacturing has brought incredible flexibility to the medical device industry, allowing for custom-designed components that fit patient-specific needs. But with this flexibility comes variability in part geometry, surface texture, and defect types. The PAQi system excels at inspecting these parts, detecting issues such as layer separation, residual powder, and inconsistencies in bonding.

Our approach for additive manufacturing inspection involves:

• Developing object detection models that can adapt to unique part shapes and orientations.

• Using advanced lighting solutions like RGBW lighting to enhance defect visibility on various surface types.

• Leveraging our annotation software to accelerate AI model training, providing fast adaptation to new part designs.
