3D Scanners

Definition

3D scanners are devices that capture the physical dimensions and appearance of an object by collecting data on its shape and surface characteristics. This technology enables the creation of a digital representation of the scanned object, which can be used in various applications such as reverse engineering, quality control, and design modification. By converting physical objects into digital models, 3D scanners play a vital role in improving precision in machining processes and facilitating on-demand manufacturing workflows.
