TrussFab - Fabricating Sturdy Large-Scale Structures on Desktop 3D Printers

Explore a groundbreaking 20-minute conference talk from the ACM CHI Conference on Human Factors in Computing Systems that introduces TrussFab, an innovative system for fabricating large-scale, weight-bearing structures using desktop 3D printers and plastic bottles. Discover how this end-to-end solution enables non-engineers to design and create sturdy trusses capable of supporting human weight. Learn about the workflow, structural analysis, and design refinement process that allows for the creation of functional furniture, bridges, boats, and even a 5-meter diameter dome. Gain insights into the efficient use of 3D-printed components combined with repurposed plastic bottles to achieve scale and strength in DIY projects.
