Abstract

A method for forming at least one three-dimensional article through successive fusion of parts of a powder bed on a support structure, the method comprising the steps of: providing at least one model of the three-dimensional article, lowering the support structure a predetermined distance and rotating the support structure a predetermined angle in a first direction before applying a first powder layer covering the lowered and rotated support structure, rotating the support structure the predetermined angle in a second direction opposite to the first direction before directing the at least one first energy beam from the at least one first energy beam source at selected locations of the first powder layer, the at least one first energy beam source causing the first powder layer on the stationary support structure which is stationary to fuse in the selected locations according to the model to form first portions of the three-dimensional article.
