Assessment framework for additive manufacturing in the AEC industry
Abstract/Contents
- Abstract
- For the foreseeable future, building components will be produced with additive (AM) and conventional manufacturing (CM) methods. Since the value of AM is currently not transparent to architects, engineers, and contractors, they cannot make well-informed decisions about the application of AM for buildings. Case studies of two metallic building components, a curtain wall frame and a bracket, carried out with a global building façade contractor demonstrated that AM is technologically feasible for building components and lowers environmental impact by up to 87% but increases cost by a factor of 5 at least. Based on the case studies, this research formalized a 19-step framework for the rapid and consistent assessment of the applicability (A) and schedule (S), environmental (E), and cost (C) implications of producing building components with AM vs. CM. The validation of the formalized semi-automated framework showed a 97% reduction of the effort required for the ASEC analyses and improved the consistency of the A, S, and C results across different assessors. The framework also improved the consistency of the E results in total by a factor of 4, but some E results remained inconsistent. An uncertainty analysis of these inconsistencies identified the uncertainty sources, quantified their impact, and proposed mitigations. A fuller automation of the framework could reduce the inconsistencies of the E analysis and further reduce the effort for ASEC assessment of AM vs. CM for buildings.
