Abstract
The present invention relates to a method for forming a three-dimensional article through successive fusion of applied powder. Said method comprising the steps of: providing at least one powder hopper comprising powder to be used for forming said three-dimensional article, providing a predetermined amount of powder at a build support, directing an energy beam over said build support causing at least a portion of said powder to sinter and causing at least a portion of said powder to bond to said build support, directing an energy beam over said build support causing said powder to fuse in selected locations according to a model to form a first portion of said three-dimensional article, rotating said build support around an axis of rotation for creating said three-dimensional article, which three-dimensional article is build up layer by layer in a radial direction with respect to said axis of rotation.
