Abstract
An additive manufacturing method for forming a three-dimensional article through successive fusion of parts of at least one layer of a powder bed provided on a work table. Providing at least one rotatable powder container above said work table, said powder container comprising at least one exit for providing powder to a powder table arranged beside said work table, at least one opening inside said container is spatially separated from and connected to said at least one exit. Ejecting a fixed amount of powder from said powder container during at least one predetermined segment of rotational angles of said powder container, from the exit of said powder container onto said powder table, wherein said fixed amount is determined by the shape and size of the at least one opening inside said container. Distributing said powder onto said work table with a powder distributor.
