To provide students with the necessary theoretical and practical means, so that they can choose to choose according to the characteristics and requirements of each type of object to be shaped and reproduced, as well as the most suitable products and materials in each case, without forgetting the care to be taken with the object to shape from the point of view of its state of conservation.
Contribute to enable students to expand their knowledge and mastery of technical processes, developing their practical skills in the areas of modeling, molding and reproduction of art objects.

To appeal to students about the need for greater awareness of the problem of object reproduction and the importance of Molding Techniques as a support discipline in the different areas of Art History, Mobile and Property Heritage Conservation and Museology and Museography.
