This work presents a bibliographic research about the manufacturing and the application of models produced by additive manufacturing in a sand-casting factory. It is presented the concept of additive manufacturing, its different characteristics and technologies and how this process is related to the sand-casting industry. Through former studies, the results are shown by way of comparison, of elements such as performance, time and cost of manufacturing, between models made by additive manufacturing and conventional models, generally made of steel, wood, Styrofoam or epoxy. It was evaluated that the 3D models showed a lower cost and time of manufacturing, a higher productivity than models made of epoxy and wood, in addition to being noted that the more complex the final part, the more advantageous it is to use additive manufacturing. It was also presented comparisons between models made by the technologies FDM and InkJet 3D Priting, with the latter being more advantageous by not having relevant defects in the final part, like it happened with the FDM part, and by having traits such as a higher cooling rate, lower total volume and weight, lower time of manufacturing and, therefore, a higher productivity. Finally, suggestions are given in order to transform this theoretical research in an empirical work.
