Resumen:
Computer assisted designing (CAD) is well known for several decades and employed for ceramic manufacturing almost
since the beginning, but usually employed in the first part of the projectual ideation processes, neither in the prototyping
nor in the manufacturing stages. The rapid prototyping machines, also known as 3D printers, have the capacity to produce
in a few hours real pieces using plastic materials of high resistance, with great precision and similarity with respect to
the original, based on unprecedented digital models produced by means of modeling with specific design software or
from the digitalization of existing parts using the so-called 3D scanners. The main objective of the work is to develop
the methodology used in the entire process of building a part in ceramics from the interrelationship between traditional
techniques and new technologies for the manufacture of prototypes. And to take advantage of the benefits that allow us
this new reproduction technology. The experience was based on the generation of a complex piece, in digital format, which
served as the model. A regular 15 cm icosahedron presented features complex enough not to advise the production of the
model by means of the traditional techniques of ceramics (manual or mechanical). From this digital model, a plaster mold
was made in the traditional way in order to slip cast clay based slurries, freely dried in air and fired and glazed in the
traditional way. This experience has shown the working hypothesis and opens up the possibility of new lines of work to
academic and technological levels that will be explored in the near future. This technology provides a wide range of options
to address the formal aspect of a part to be performed for the field of design, architecture, industrial design, the traditional
pottery, ceramic art, etc., which allow you to amplify the formal possibilities, save time and therefore costs when drafting
the necessary and appropriate matrixes to each requirement.
