Using as an example the simplest shape of a truncated hexagon, which differs from a regular hexagon by the absence of one row of elements on one side, this paper discusses assembly errors and the causes that generate them. A general-purpose method for the oriented assembly of an ordered hexagonal structure is proposed that can be used in both a one-stage and in a two-stage process. It essentially consists of introducing additional relief into the original shape that provides reliable identification of the position of the assembly element and that eliminates the effect of azimuthal and mirror rotations. A patent has been obtained on the method, and its efficiency has been confirmed by fabricating fiber structures with a resolution of 90 line/mm, using the two-stage process.
