Free Content Structural aluminium nodes in free form reticulated structures - geometric variables and manufacturing constraints

This paper discusses and describes the geometry and manufacturing of nodes in free form reticulated shell structures. Reticulated shells are commonly produced with steel nodes, providing new design solutions aluminium has different manufacturing constraints. The paper presents manufacturing methods for mass customized aluminium nodes and discusses the future potential of aluminium as a structural material for free form shells and spatial structures. The node's relation to the global shape, the grid division and the design choices is presented. Based on this, the future potential of aluminium nodes in free form reticulated shells is discussed.
