How It Works

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. Read our customer case studies to see how organizations like Medi, Rise Bionics, and Bath Fitter use Structure technology to improve patient outcomes and business results.
