New manufacturing digital processes of free-form GRC panels

Free-form GRC panels are widely used in lightweight facade elements. Such panels can be manufactured through a variety of methods. Nevertheless, its advantages such as moldability, durability and lightness, are penalized by the high price of the corresponding molds, especially if there is not a sufficient repetition of units. New digital technologies enable innovative possibilities in the field of construction and manufacture of molds with complex geometries. In this paper, a series of manufacturing methods for free-form GRC panels are presented. Advantages and drawbacks of these methods are discussed, especially the role played by the mold and its economic impact. Finally, conclusions of this analysis about its technical feasibility and possibilities are drawn.
