A collection of electronic devices specifically designed for the purpose of creating three-dimensional objects. These devices, known as 3D printers, use digital models to produce physical objects, layer by layer, from various materials, often plastic or metal. They are commonly used in a variety of fields including manufacturing, prototyping, and product development. Falling under the umbrella of office electronics, they are often found in professional settings, academic institutions, and increasingly in homes. As part of the broader electronics category, they incorporate advanced technology and require a power source to operate.
