Feasibility study of additive manufacturing for metallic façade components
Abstract/Contents
- Abstract
- The state-of-the-art analysis of additive manufacturing (AM), popularly known as 3D printing, shows that the coexistence of AM and conventional manufacturing (CM) currently used in the practice, is a reality today. However, since Architecture-Engineering-Construction (AEC) practitioners are not informed about the value of AM through transparent metrics like cost and schedule they are unable to make well-informed decisions about the application of AM in the building sector. To address the lack of information about the value of AM for AEC and the lack of well-documented studies of AM vs. CM for building components, I developed and conducted a feasibility study in collaboration with Permasteelisa Group, the global leading façade contractor. The Feasibility Study was designed to determine the applicability, costs, and the duration of manufacturing of two metallic curtain wall (CW) components using AM and to compare these figures with CM. The study demonstrated that AM for building components is technologically feasible, but is cost-prohibitive today. For all cases, the manufacturing cost and duration were about 90% higher or 90% longer, respectively, than for the related CM components. The applicability analysis showed that two of the analyzed AM technologies with small-scale platforms, direct metal laser sintering (DMLS) and electron beam melting (EBM), produced by EOS and Arcam, are suitable for AM of building components in geometric size that fit in their build chambers. Large-scale metallic components can be produced with large-scale metallic deposition technologies, produced by Sciaky Inc., DM3D, Optomec, and Fabrisonic. Further AM cost and manufacturing time reductions are expected with ongoing AM technological development. Future work includes analysis of other performance criteria such as environmental impact of AM vs. CM to provide more comprehensive conclusions about the AM's potential for AEC.
