Their common uses include fieldwork, scanning books, barcodes, or small documents while traveling, and they are particularly praised for being lightweight and affordable.
3D scanners capture the shape and depth of objects to create a three-dimensional digital model, utilizing technologies such as laser triangulation or structured light to generate highly accurate representations. These scanners are commonly used in product design, 3D printing, manufacturing, and medical imaging. While they allow for the creation of detailed 3D models, they can be and require specialized software and knowledge for editing and processing.
Sheet-fed scanners pull individual sheets of through the scanner automatically, making them ideal for scanning multiple documents quickly. They feature an Automatic Document Feeder (ADF) for scanning multiple pages and are designed for documents, not thick items like books.
