Abstract: Various embodiments of the present invention relate to a method of using of a focus lens in additive manufacturing for forming a three-dimensional article through successive fusion, with a high energy beam, of parts of at least one layer of a powder bed provided on a work table, which parts correspond to successive cross sections of the three dimensional article, said method comprising the step of: using said focus lens for varying a spot size of said high energy beam on said powder bed as a function of an already fused thickness of said three-dimensional article below said powder which is to be fused. The invention is also related to a method for forming a three dimensional article.

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 method for forming a three-dimensional article through successive fusion of locations of a powder bed. The method comprising: providing a model of said three-dimensional article; applying a powder layer on a work table; determining a maximum scan length of an energy beam; directing said energy beam from a first energy beam source over said work table with constant energy causing said first powder layer to fuse in first selected locations according to said model to form a first cross section of said three-dimensional article, wherein locations with a shorter scan length than said maximum scan length is provided with a time sink before and/or after said scan line so that the time period between each two adjacent scan lines is constant throughout the manufacture of said three-dimensional article.
