The AM processes allow the manufacture of engineering products with more complex structures. These AM technologies are very meaningful to apply in the practice with the aim of reducing new product development cycle time. Nowadays, the number of machines and these technologies is increasing, depending on the flexible capabilities in the marketplace and it is intractable for a customer to select the right machine and technology to implement at the small and medium enterprise (SME) because it relates many complicated factors which conflict together. Therefore, this paper presents the general view on the application of multiple criteria decision making methods to support the decision makers, especially engineers, engineering managers and technicians. In particular, the advantages and disadvantages of each AM technology are also analyzed to strengthen the customers knowledge. Then, this paper proposes a model for multi-criteria decision making in evaluating and selecting the technology alternative for manufacturing SME and the personal purpose.
