| summary |
This paper introduces an innovative integrated approach to design, simulate, and test assembly strategies that adapt to tolerances and geometric variations. Traditional Design for Assembly (DfA) methods, while effective for well-known materials and predetermined design parameters, exhibit limitations in addressing unknown parameters and unpredictable material behavior. Our research employs techniques such as 3D scanning, laser projection, and early 1:1 prototyping to develop a flexible adaptive assembly model, accommodating last-minute structural and site condition changes.
We demonstrate our novel workflow through the assembly and installation of a large-scale demonstrator at the AEDES gallery in Berlin, consisting of 24 variable-size 3D printed panels attached to a brick wall. By creating an initial assembly model using early detailing and a preliminary assembly sequence, we maximized the number of adaptable design parameters. An agent-based model was utilized to identify wall connection locations based on site constraints and fastener accessibility. Upon completing panel production, we used industrial laser projectors to compare digital files to actual pieces and 3D scanning to acquire accurate panel connection positions. This information enabled the regeneration of connection points with precise angles and dimensions and informed the final assembly sequence. On-site laser projection facilitated the efficient assembly of the structure. Our approach paves the way for more accurate and adaptable construction methods in complex architectural projects. |
