Meet the Structure Sensor 3

3D Scanning Technology Built for Healthcare and Industry

Structure builds professional-grade 3D scanning hardware and software for medical, clinical, and industrial applications. Our flagship product, the Structure Sensor 3, attaches to any compatible iPad to deliver sub-millimeter depth accuracy — enabling clinicians, prosthetists, orthotists, and developers to capture precise body measurements in seconds.

Healthcare providers trust Structure technology across a wide range of clinical workflows: custom orthotic and prosthetic fitting, wound measurement, surgical planning, and patient monitoring. The Structure Capture app — compatible with iPhone TrueDepth cameras, iPad LiDAR, and all Structure Sensor hardware — lets any care team member capture publication-quality 3D scans without specialized training.

Developers building depth-sensing applications use the Structure SDK to integrate Structure Sensor 3 directly into iOS apps, with access to raw depth frames, mesh extraction, foot measurement, and offline licensing. The SDK powers hundreds of apps across healthcare, industrial inspection, retail fit-tech, and augmented reality.

Structure is based in Boulder, Colorado, and serves customers in over 50 countries. Our sensors are used in peer-reviewed clinical research, FDA-cleared workflows, and enterprise scanning deployments worldwide.
