Abstract: Disclosed is a method for manufacturing three-dimensional articles with porosity. A model is created of a porous structure, said creating step comprising the steps of: defining a three-dimensional space comprising a predetermined pattern of nodes, wherein said nodes are connected together in a predetermined manner with struts, moving each node in said three-dimensional space a randomized distance, which distance is less than a predetermined value and in a randomized direction, slicing said three-dimensional space into a predetermined number of two-dimensional layers with a predetermined thickness, slicing said three-dimensional article into two-dimensional layers with a predetermined thickness, applying one two-dimensional layer of said article on one two-dimensional layer of said porous structure resulting in a porous two-dimensional layer of said article, repeating said applying step for all two dimensional layers of said article, manufacturing the three-dimensional article with porosity according to the model by exposing fusible material to an energy source.
