AN ARTICLE FORMED BY RESPECTIVE LAYERS

The invention relates to an article formed by respective layers stacked in a z-direction perpendicular to the respective layers. The article comprises a wall structure extending in the z-direction and formed by line segments of the respective layers, each of the line segments of the wall structure lengthwise extending in a longitudinal direction such that the wall structure also extends in the longitudinal direction. Parts of at least some of the line segments are shifted within the respective layers perpendicular to the longitudinal direction and relative to the line segments of neighbouring layers of the respective layers such that the wall structure protrudes perpendicular to the longitudinal direction and the z-direction alternatingly along the z-direction. The method further relates to a method of printing a wall structure, and a computer system for providing a wall structure.
