Changing Butterfly: a Large 3D Printing Work Based on Structural Mechanics
How to realize mechanical butterfly-like shell and design efficient construction details for resembling, posed problems and challenges to the design and construction of a large 3D printing work. Firstly, through analysis of the synergetic mechanism of butterfly-like morphology and structural mechanic of Hypar shell, digital design methods and adjusting modes were well studied. Secondly, based on the features of additive manufacturing, adaptive methods of unit division and construction were proposed and discussed. Moreover, changing modes of lights were tested through the combination of photoelectric numerical control and corresponding details design. As a result, not only the construction of 3D printing work of large scale butterfly-like shell, but also more than 100 new changing patterns of lights were realized.
