3D printer is a printing technology machine that uses digital models to create physical objects by depositing material layer by layer. The process is called additive manufacturing, as opposed to traditional subtractive manufacturing methods that involve removing material from a larger block or piece to shape it. 3D printers use a variety of materials, such as plastics, metals, ceramics, and even food products, to create objects of various shapes, sizes, and complexities. The digital models used as the input for the 3D printer can be created using specialized software, 3D scanners, or downloaded from online databases. The applications of 3D printing are vast and include prototyping, product development, architecture, engineering, medicine, education, and even art. The technology has enabled faster, cheaper, and more accessible manufacturing, allowing for greater customization and personalization of products.
