3D printer also known as stereoscopic printing, additive manufacturing, or amalgamated manufacturing (AM), it can refer to any process that prints three-dimensional objects. Three-dimensional printing is primarily an additive process in which raw materials are laminated under computer control. The content of a 3D print can be derived from a 3D model or other electronic data, and the printed 3D object can have any shape and geometric characteristics. Three-dimensional printers are a type of industrial robot. 3D printers built with aluminum profiles from v slot are very robust and sturdy, and look beautiful.
