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.
Méthode de fabrication de produits métalliques ou non métalliques par frittage laser sans structure imposée, dans laquelle les produits sont fabriqués à partir d'un matériau poudreux sur une plaque de substrat de manière verticalement additive, couche par couche au moyen d'un faisceau laser commandé par ordinateur, caractérisé en ce qu'au moins un support est fabriqué entre la plaque de substrat et la surface externe du produit, ledit support étant relié par l'intermédiaire d'une zone de rupture prédéterminée avec la surface externe du produit, la zone de rupture prédéterminée étant formée par réduction de la résistance du support le long du contour extérieur du produit.
