The device commonly used for creating 3D printed objects is a 3D printer. This technology allows the production of three-dimensional objects from a digital model by layering materials, often plastics, resin, or metals. The process begins with a 3D design created using CAD (computer-aided design) software. The printer then interprets the design and lays down layer upon layer until the object is fully formed. 3D printers are widely used in various industries, including manufacturing, healthcare, and architecture, for producing prototypes, custom parts, and even end-use products.
