Abstract:
1. A method of fabricating a three-dimensional container comprising a multitude of two-dimensional faces that form a hollow polyhedral shape and containing a fillable center chamber, wherein the multitude of two-dimensional faces are permanently held together by solid hinges, the method comprising: (a) depositing a sacrificial layer on a substrate to form a first layer; (b) depositing a conductive second layer on the first layer to form a layered substrate; (c) patterning the layered substrate to fabricate a multitude of patterned two dimensional faces; (d) patterning a hinge on an interface between adjacent patterned two dimensional faces; (e) patterning a hinge on an edge of the patterned two dimensional faces, wherein the hinge between two adjacent faces has a width that is about twice a width of the hinge on an edge; (f) depositing a material that can be liquefied on each hinge patterned in step (d) and step (e); (g) dissolving the sacrificial layer to release the patterned two dimensional faces therefrom; (h) heating the released patterned two dimensional faces to liquefy the material that can be liquefied deposited on each hinge, thereby self-assembling the three-dimensional container containing a fillable center chamber, whereupon cooling, the self-assembled three-dimensional container forms a three-dimensional container comprising a multitude of two dimensional faces permanently held together by solid hinges.
