A 3D Printer is a revolutionary device that creates three-dimensional objects by layering materials based on digital models. This technology has transformed various industries, including aerospace, automotive, and healthcare, allowing for rapid prototyping and customized production. 3D printers work by using materials such as plastic, metal, or resin, which are deposited layer by layer to form the final product. This process not only reduces waste compared to traditional manufacturing methods but also enables the creation of complex geometries that were previously impossible to achieve.
