What is a 3D scanner?

A 3D scanner acts as a digital set of eyes, capturing the precise physical dimensions, curves, and angles of real-world objects to create a detailed digital model. By using technologies like lasers or structured light to measure an object's surface, the device gathers millions of data points, known as a "point cloud," which is then converted by software into a usable 3D file. This technology is a game-changer for industries needing to reverse-engineer broken parts, ensure manufacturing quality control, create custom-fitted products like medical gear, or digitally preserve historical artifacts.
