Guide to implementing digital twins in additive manufacturing with rami 4.0

This study was designed to guide the creation of digital twins for Industry 4.0 in additive manufacturing, especially for the RAMI 4.0 standard. As additive manufacturing tends to grow and evolve in the coming years, a guide is of fundamental importance to facilitate its implementation in the most varied types of the production process. The method used for the preparation of this guide was the scientific-technological one, mainly it's the technological part, which consists of the elaboration of a prototype, proceeds with the accomplishment of the tests and necessary adjustments to adapt to the previously established performance parameters, and ends with the presentation of the final product. The results showed the need for knowledge of the execution of eight technologies that facilitate the implementation of digital twins: G-Code, Wi-fi, FDM Additive Manufacturing, Printer Configuration, Controller Board, OPC UA, MongoDB, and System Architecture.
