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.

First claim

The invention claimed is:

1. 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, wherein an axis of rotation of said build support is provided in a horizontal direction;
directing an energy beam over said build support causing at…
