Open Frame

This research project seeks to find an affordable, accessible method for creating freeform space frame structures with conventional desktop 3D printers. Emerging research in 3D printing custom structural connections has expanded the geometric complexity and design opportunity for architectural scale space frames. However, these developed methods are labor intensive, require sophisticated 3D printing technologies and are limited to computationally skilled users. This research expands the field of 3D printing of joints for space frame structures by developing: 1) A joint system based on flexible material and internal structure of the joint, 2) A framework that utilizes widely available additive manufacturing technologies for the production of 3D printed joints paired with standardized, off-the-shelf components. 3) A user interface to allow users of any skill level to design, generate digital files, and fabricate their own space frame structures using desktop 3D printers. The developed method and UI was verified through the design and construction of a 1:1 scale space frame structure made of 70 joints and 150 tubes. This structure was fabricated on a desktop 3D printer and assembled in less than a day with simple, widely available tools. Ultimately resulting in a new flexible joint system, an affordable and accessible digital design to fabrication framework, a UI, and a 1:1 scale demonstrator.
