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.

Abstract: The invention relates to a platform device (4) for forming a three-dimensional article (2) in an additive manufacturing machine layer by layer by successive fusion of selected areas of powder layers (3), which selected areas correspond to successive layers of the three-dimensional article. The platform device (4) has a support member (5) with a surface (6) for receiving powder. The support member (5) is rotatable about a first rotation axis (13) extending in a direction (15) substantially perpendicular to the surface (6). The support member (5) and the first rotation axis (13) are rotatable about a second rotation axis (14) arranged substantially in parallel with and off-set to the first rotation axis (13).
