We’re in the beginning phase of using Fologram as a fabrication tool in assembly of complex space frame that folds from flat cut sheets. The kirigami space frame system Spin-Valence, when used to produce flat or single-direction curvature, has assembly logic relatively well encoded into the cut parts. For double-curved versions it is less clear how assembly should proceed, so Fologram is very useful.
Each unit in the assembly is a slightly different size and will deploy into different configurations. We will begin this work by developing a Fologram working environment that will allow us to accurately deploy units one by one during assembly. The goal is to use steel to produce the pavilion design pictured here, but we will begin by testing the accuracy of deploying 3D Spin-Valence units into specific configurations. Once that is successful, we will move to larger assemblies.
I’ll also attach a small steel double-curved assembly that I put together without the help of AR. There are inaccuracies because our computational model produced imperfect geometries at that time (it has since seen many updates), and because of inaccuracies in assembly. Now that we have addressed the digital geometry, we need to address the accuracy in assembly.
We welcome any feedback on this work, and we’ll continue to post updates as we progress. We are interested in methods that we can use so that the Fologram model will provide visual feedback to the fabricator when the deployment is within construction tolerance (color change, or other cue).
I was only allowed to post one image, so many of these will not appear… next time, I guess.
flat version of Spin-Valence for reference
single unit similar to lower image will be deployed into non-parallel configuration that is unique to each unit. we will place flat part onto a surface aligned with digital model, and then deploy the unit hub into final configuration based on Fologram model.
