EM3D vs Structure Capture, 3D Scanning

Use Mirror Saver as a second screen when 3D scanning with EM3D: Ethan Makes 3D Scanner. Since EM3D uses the high resolution front-facing True Depth sensor, it can be difficult to scan anything other than yourself because you have to point the screen of the scanning device toward the object being scanned. The Mirror Saver feature in EM3D allows you to broadcast the screen to another iOS device, so you can hold the devices back to back and see what you're scanning . However, EM3D requires iOS 13 or higher. Devices that don't have iOS 13 or higher can download the standalone Mirror Saver app, which provides the screen functionality of the Mirror Saver feature.

Structure Capture is a mobile 3D scanning app that transforms your iOS device into a powerful, portable tool for clinical and professional use, including healthcare, orthotics & prosthetics (O&P), custom medical garments, and product design. Built for professionals, it enables fast and accurate body or object scanning using either the Structure Sensor 3 or Apple’s TrueDepth and LiDAR camera technologies. Clinics, labs, and manufacturers worldwide trust Structure Capture for its precision and reliability in scanning limbs, body parts, and complex shapes. Supporting digital workflows from scan-to-CAD/CAM fabrication, Structure Capture allows seamless export of industry-standard 3D file formats (.OBJ, .STL, .PLY), making it a top solution for orthotists, prosthetists, medical device companies, and product designers seeking efficient integration into their modeling and manufacturing pipelines.
