The manufacturing industry has developed since the industrial revolution, however with the evolution of some advanced technologies and the diffusion of specialized computer-aided design (CAD) software, the traditional way of producing products may be about to change. According to E. Sachs, two needs, fundamental for productivity and industrial competitiveness, are the reduction of time to market for new products and the flexible manufacturing of products in small quantities [1]. One factor that contributes to the product design process is the development of prototypes, defined as a basic model that can be tested and has features that can only be seen when a physical product exists. This phase also allows customers to test ideas and provide feedback, which can improve the final product. A term used in the manufacturing process is Rapid Prototyping (RP), which describes a process for quickly creating a system or representation of a part before final release or commercialization. . Although as the technologies have developed, users have noticed that this term does not effectively describe the latest applications of the technologies. The basic principle of these RP technologies is that they all manufacture parts using an additive approach; this is one reason why recently adopted ASTM standards now use the term Additive Manufacturing (AM) for these processes [2]. A key difference that we can observe is that in the mentioned processes, instead of having a piece of raw material and using tools to cut, drill and remove parts from it until the desired shape is obtained, these techniques build the product layer by layer and then generate little or no waste compared to traditional methods. While it eliminates...... half the paper...... which offers the advantage of working with advanced ceramics and alloys, it can be used to fabricate products for high-end applications requiring good mechanical and thermal properties, such as the aerospace industry or the luxury car sector. On the other hand, foot-and-mouth disease affects a more common range of sectors; products made using this process, although they have good mechanical properties, are unable to withstand high temperatures or loads. However, rather than seeing them as simple prototyping processes, they have evolved rapidly and are now capable of providing fully functional products and even improving some areas with their inherent additive manufacturing feature. There are few industries taking part in this radical change today, however, as the technology spreads and becomes cheaper, SLS and FDM will lead the next manufacturing revolution.
