What Are 3D Scanners?
3D scanners are devices that capture the shape—and in some cases the colour and texture—of a three-dimensional object. Using technologies such as structured light, laser scanning or photogrammetry, the scanner collects millions of points from the object to generate a point cloud, which is then converted into a 3D model. These models can be used for reverse engineering, digital editing, simulation, 3D printing or technical documentation.
How Do 3D Scanners Work?
A 3D scanner captures the shape of an object using a laser beam, structured light, or photographs taken from different angles. This data is processed by specialised software to reconstruct an accurate 3D model. The final result can then be exported in common digital formats such as STL or OBJ, ready for modelling, analysis or printing.
When to Use a 3D Scanner
- In design and prototyping: to digitise physical components, perform reverse engineering or modify existing models.
- In 3D printing: to faithfully reproduce physical objects or make changes to designs based on real-world items.
- In education and training: as a teaching tool for technology, anatomy, art or engineering subjects.
- In heritage conservation: for documenting sculptures, artworks or archaeological pieces.
- In industrial quality control: to compare physical parts with their digital models and verify tolerances.
Advantages of Using High-Quality 3D Scanners
- High precision and detail: capable of accurately capturing the geometry of even complex or irregular objects.
- Fast digitisation: significantly reduces the time required compared to manual measurement or creating models from scratch.
- Ease of use: many models are plug & play, with intuitive interfaces and automated software.
- CAD/CAM software compatibility: enables direct use in design, engineering or manufacturing workflows.
- Versatile applications: suitable for a wide variety of professional and educational uses.
