Abstract

Lattice (1) comprising multiple branches (2) and joints (3) connecting the branches (2), wherein characterized in that the lattice (1) is formable into a desired shape and exhibits at least two positions, a first position wherein the joints (3) enable that an outer circumference of the lattice (1) conforms and is moved to the desired shape, and a second position wherein the lattice (1) is locked into said desired shape, wherein the lattice (1) exhibits multiple degrees of freedom enabling the lattice (1) to assume an arbitrary external shape, said shape de- fining a boundary with an internal volume, and wherein said lattice (1) is present inside said internal volume so as to provide the boundary with structural rigidity when in the second position wherein the lattice (1) is locked.
