What is a 3D Printer

3D printing is any of many processes used to make a three dimensional objects. In 3D printing, additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape and are produced from a 3D model.

3D printing in the term’s original sense refers to processes that successively deposit material onto a powder bed with inkjet printer heads. More recently the meaning of the term has expanded to include a wider variety of techniques. Technical standards generally use the term additive manufacturing for this broader sense.
