What Is 3D Printing?
3D printing involves various processes to yield a three-dimensional object. Alternate layers of material are formed with the control of a computer to create a desired object. The object can be almost any shape and is usually produced based on a 3D model. The printer itself is a type of industrial robot. The original sense of the term 3D printing refers to laying down successive layers of material onto a powder bed with inkjet printer heads. More recently, the definition of the term has expanded to include a variety of techniques.
