TrussFab allows users to design sturdy, usable structures (e.g. tables, chairs) from soda bottles. The user inputs the desired shapes, sizes, etc. (or an existing 3D model) and the software applies engineering expertise to optimise the design and ensure it is structurally sound. The user can iteratively edit the design, and TrussFab will show warnings if the structure is not sound. The system then creates the ‘hubs’ that connect the soda bottles and these can be 3D printed.
‘TrussFab embodies the required engineering knowledge, allowing non-engineers to design such structures and to validate their design using integrated structural analysis. We have used TrussFab to design and fabricate tables and chairs, a 2.5 m long bridge strong enough to carry a human, a functional boat that seats two, and a 5 m diameter dome.’
