The AM technologies have been spreading during last decades as alternative to the traditional subtractive production processes such as turning, milling, and drilling. These technologies are taking hold in all sectors alongside, improving or replacing traditional production techniques. In the jewelry industry additive manufacturing is beginning to settle as the main prototyping tool and is slowly starting to be used directly for the finished product. In the chapter 1 a general overview of the AM technologies is presented. After a brief outline of the history, the classification of the techniques available according to the material form (liquid, solid or powder) is accompanied with a brief description of the industry and the application fields.
