Abstract
A method is provided for production of at least one three-dimensional article by successively providing powder layers and fusing together of selected areas of the layers, which areas correspond to partial cross sections of the three-dimensional body. The method involves: applying a first powder layer on a work table, fusing the first powder layer in the selected areas, the selected areas being a full contour of the three dimensional article and a first portion of an inner area of the three-dimensional article, and fusing a second portion of the inner area of the three-dimensional article in the first powder layer completely when the first powder layer is covered with at least one second layer, the second portion being distinct relative to the first portion.
