Through the expansion of Industry 4.0, the Oil & Gas industry in the world is undergoing a major transformation, so that the formalization of a process chain for the manufacture of spare-parts becomes increasingly necessary. This work aims to create work patterns using the concepts of industry 4.0 applied to the Oil & Gas industry, through the study of several work- pieces of this area. All spare-parts were used to create a chain of manufacturing processes. From there, they were recreated through different digital or hybrid manufacturing techniques. Several points such as geometry, type of acquisition of geometry, types of raw materials, types of manufacturing technology and machinery were addressed. Mechanical tests were carried out at different stages of the process. The results obtained formed a basis for strategies aiming solving problems of the studied spare-parts, using hybrid and additive manufacturing techniques, combined with the concepts of Industry 4.0. The created protocol was a descriptive and detailed standardization of the production chain process. The evaluation of the processes, justifications and solutions was applicable for each demand, generating a virtual catalog of spare-parts and that fed a cyclical model of experiences that continually update the database itself.

The use of 3D printers in additive manufacturing are very common at the last years. The structure, size, movements and type of materials of the printers changes according the use, topology and form of the object that be printed. Although 3D printers are becoming more widespread in the industry and for residential consumers, the size and density of pieces is still a challenge principally at larger pieces. This paper presents all details and specifications of an open-source large 3D printer that uses PLA or ABS, with the aim to verify the impact of these transformations and uses for engineering and industry in general.
