What Is a 3D Scanner?
A 3D scanner is a device that captures the shape of a physical object and converts it into a digital 3D model.
These digital models can be used for design, inspection, documentation, or manufacturing.
3D scanning technology is used in industries such as engineering, healthcare, archaeology, and product design.
How 3D Scanning Works
Most modern 3D scanners use optical methods to capture surface geometry.
These methods may include:
-
structured light scanning
-
laser triangulation
-
photogrammetry
The scanner records thousands or millions of data points from the surface of an object.
These points form a point cloud, which can be converted into a digital 3D model.
Common Uses of 3D Scanners
3D scanning is used in many fields.
Typical applications include:
-
reverse engineering
-
product design
-
digital archiving
-
quality inspection
-
cultural heritage preservation
Because scanners capture full surface geometry, they can provide detailed digital representations of complex objects.
