Abstract
3D-printed construction allows elaborating building elements with diverse shapes that are digitally controlled. This paper exposes the modeling of 3D-printed curved walls through parametric programming in building information modeling (BIM) in order to support a cost-efficient building design. The advantage of using curved walls is based on the possibility of reducing their thickness with respect to straight walls of similar length given their higher resistance to overturning forces. The programming developed here can propose a considerable set of solutions using curved walls for a rectangular enclosure of dimensions given by the user. A case study for a vehicle sale pavilion is shown, for which a set of 1,600 solutions with curved walls of different curvature angles and lengths is generated and subsequently analyzed. From this analysis, those models with lower material consumption and execution time are selected to be more thoroughly studied in the design process. Thus, a novel strategy is provided to researchers and practitioners for developing more efficient and expressive building designs based on 3D-printed construction. The most efficient solution identified in the example reduces material consumption by 61%, with an estimated cost saving of 53%.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
