Constructive Design: Rule Discovery for 3D Printing Decomposed Large Objects

This proyect presents a rule discovery process for designers that work with physically large 3D printed models. After a period of discovery, rules were formalized, then d eveloped into operations and programmable functions used in a generative design system. Past examples of generative systems are built based on visual constraints leading to graphical outcomes. With the emergence of 3Dprinting, we introduce ideas for rule building based on physical constraints and outcomes. The decomposition rules are: curved surface slicing, freestanding attribute, interval patterning, edge mating, and pneumatic attribute. The freestanding attribute, the most novel rule, is based on Chilean anti-earthquake building techniques. This rule provides the greatest degree of structural stability to a model. We conclude with a discussion of results from the case study used to generate the set constructive rules. We delieve this method of module generation, 3D Printing and assembles can support design prototyping and model manufacturing across scales.
