3D-printed constructions express the capacity of automated technologies to elaborate buildings through additive manufacturing. These constructions require an architectural design according to their manufacturing conditions. This research reviews buildings that have been executed with these technologies in order to determine architectural characteristics. From an Internet search, a register was compiled of 112 cases of 3D-printed constructions around the globe. They include some 10,000 m2 of built surface area and were mainly erected in the last five years. The review shows that cases were built by approximately thirty executors, mostly entrepreneurs’ companies who have made different buildings as single-family dwellings constructed with gantries or robotic arms, either on-site or in factories. Most of the components printed are walls, with single or double filaments with interior voids. In some cases, they integrate reinforcements and openings. The geometry of the 3D-printed constructions varies between orthogonal layouts that replicate existing buildings and spherical shapes that reflect printing capabilities. Many of the cases are a combination of these characteristics, mixing a technological adaptation to existing architecture and new operative conditions. This review reveals the emerging development of this construction system with the progressive consolidation of some architectural attributes.
This paper proposes the development of a methodology for the digital generation of valid 3D-printed houses designs and fabrication programming, in the search for an emerging architectural language of this technology. The aim is to develop a transparent, generic and variable modeling and management process, based on some parametric patterns for 3D printing, architectural and construction design knowledge. That serves as an outline or insight of what can be designing architectural 3d-printed forms in the Construction 4.0 era. Preliminary results, discussion and further work are presented.
Undergraduate design studies for digital fabrication and non-standard architecture are complex as their participants are usually far from systems thinking and have a basic level of confidence in the use of advanced digital tools. Furthermore, in the face of high formal complexity, the understanding of the structural system and its effects for the inhabitant are not evident. This work presents an implementation of Virtual Reality to introduce Latin American architecture university students to digital fabrication and parametric design, taking as its main premise that during the initial design stage, the designed architecture using virtual reality techniques and spatial perception can engage students to appreciate the value in these new designs, formulating new arguments and paradigms to further contribute to their training as contemporary professionals.
