Fibra de vidrio4/3/2023 ![]() ![]() Design free-form pieces usually leads to surfaces hardly or impossible to reach by repetitive panel addition. Recent architectural projects increasingly incorporate free-form façade elements, easily achievable by current computer drawing tools. This reduction in cost comes from the customization of every piece, since no tooling or molding is required. Using 3D printing processes to provide the form and GRC as a reinforcement layer, the manufacturing of complex double-curved panels is achieved more efficiently and economically. Experimental prototypes are presented to prove the feasibility of this proposal. ![]() This paper proposes an innovative approach that allows the production of custom one-off GRC free-form panels. Moreover, double-curvature panels frequently have to be manufactured as a unique piece, producing each one as an individual mold ( Pronk, Rooy, & Schinkel, 2009).ģD printing is a novel process in the construction industry and has many advantages, such as being a tool-less process, producing individual components and allowing a great freedom of geometry ( Castañeda, Lauret, Lirola, & Ovando, 2015), which would not be economically sustainable with traditional manufacturing techniques ( Hauschild & Karzel, 2011). ![]() Nevertheless, such sinuous virtual pieces are difficult to produce, expensive, time consuming and require highly qualified labor. In the digital age, sophisticated computer programs are easily capable of generating complex 3D designs. Free-form architecture is one of the most significant trends in contemporary architecture. ![]()
