The portion of the object being scanned is highlighted in red. After the scan is completed, users can change the scan mode.

Scan 3D machines are available in different types, which include:

• Handheld Laser Scanners: These scanners can be maneuvered freely to scan laser lines on the target object. They are best suited for large objects and areas that are traditionally difficult to access.
• Desktop Laser Scanners: These scanners are best suited for small and mid-sized items. They have a fixed scanning head that rotates around the device's axis while the object rotates.
• White Light Scanners: These laser scan 3D machines use a different technique by projecting a pattern of white light onto the scanned object. The scanner then processes the deformed light to create a point cloud within the object. This method works well for reflective or transparent items that are usually difficult to scan.
• Structured Light Scanners: These machines project a series of structured lights onto the object. They then calculate the deformation of the projected light to create a 3D model. This technique is fast and accurate and works well for fixed items.
• Photogrammetry Systems: These machines rely on multiple photographs taken from various angles around the item. The photos create a 3D model. It is versatile and can be used for large or small items.
• CNC Laser Scanners: These machines have a mounted laser scanner on a CNC machine. It can be used to scan after the machining process to check if the part meets the required specifications or to create an initial scan before starting the CNC machining.
