Integrated design strategies for multiscalarbiopolymer robotic 3d printing

Additive manufacturing technologies have the potential to initiate changes in architecture’smaterial culture and move us towards a bio-based paradigm. Robotic 3d-printing can proposenew design languages, logics and tectonics specific to wet biopolymers. In this paper we presentstrategies and workflows for cellulose-based biopolymer 3d-printing. We propose a digital designframework informed by the fabrication system and guided through human design input. The workflowstabilizes the material at the scale of the toolpath, the component, and the wall assembly, byintegrating joinery and cross-bracing together with the component geometry. We showcase thefeasibility of a large-scale dry-assembly of 3d-printed biopolymer components. The demonstratorwall allows us to evaluate our workflows and discuss the challenges and implication of bringingbiomaterials in our built environment.
