Abstract
A method for making metallic or non-metallic products by freeform laser sintering, in which the products are fabricated from powdery material on a substrate plate in vertically additive, layer-by-layer fashion by means of a computer-controlled laser beam, characterized in that at least one support is fabricated between the substrate plate and the outer surface of the product, said support being connected via a predetermined breaking area with the outer surface of the product, wherein the predetermined breaking area is formed by reducing the strength of the support along the outer contour of the product.
