The housing demand in Latin America has promoted to build big complexes with repetitive designs to ensure their execution and commercialization, but neglecting the differences in occupation, cultures, ages, abilities, genders, climates and locations. Producing low quality, environmental deterioration and social alienation. This work exposes a parametric programming and robotic construction strategy to develop a varied residential process. Based on structural volumes and 3d-printed walls, to provide a diversity of housing configurations. The modular generation of volumes and development of the envelope is programmed to meet various thermal and occupational conditions, with printing trajectories for the walls according to the equipment, execution processes and material capacities. A repertoire of 494 residential volumes has been defined and prototype walls have been made, suggesting an innovative design system, wich provides a new paradigm for housing construction with digital technologies and robotic execution to diversify residential quality.

Recepción/ 03 de noviembre 2020 Aceptación/ 13 de abril 2021 RESUMEN/ Las construcciones mediante impresion-3D pueden reducir recursos y tiempos de ejecución, impulsando la productividad y la sustentabilidad de la edificación. Si bien esta nueva tecnología se está desarrollando en distintas partes del mundo y ya hay ejemplos diversos, no se han determinado las condiciones de diseño arquitectónico con este nuevo sistema constructivo. El presente trabajo realiza una novedosa identificación de características arquitectónicas de la construcción impresa-3D basadas en pruebas experimentales, estudios de casos y modelaciones digitales con el fin de promover estas edificaciones. Las pruebas a escala de laboratorio, con mezclas de microhormigón y un Robot Kuka R120, han permitido elaborar diversos elementos constructivos. Además, se revisan ejemplos internacionales de viviendas impresas y se analizan sus condiciones formales. También se desarrollan modelos tridimensionales en BIM basados en las pruebas y condiciones registradas. Las experiencias y las revisiones muestran primordialmente la impresión de paramentos rugosos y curvos que sugieren nuevas posibilidades arquitectónicas. ABSTRACT/ 3D-printed buildings can save resources and time, boosting productivity and the construction's sustainability. While this new technology is developing around the world and examples abound, its architectural design conditions have yet to be determined. This work accomplishes a novel identification of the architectural features of construction 3D printing based on pilot tests, case studies, and digital modelling. Lab scale tests -with microcement and a Kuka R120 robot-have led to the development of different constructive elements. In addition, international models of impress housing are reviewed, in addition to discussing their formal conditions. BIM tridimensional models are also developed based on the registered tests and conditions. The experiences and reviews basically show the printing of curved and coarse parameters that point to new architectural possibilities.
