The present invention is directed in one aspect to methods of making free-
standing, internally-supported, three-dimensional objects having an outer
surface comprising a plurality of intersecting facets wherein a sub-set of the
intersecting facets have a diamond layer of substantially uniform thickness.
The diamond layer may be formed by chemical vapor deposition (CVD) over the
surface of a substrate that has been fabricated to form a mold defining the
sub-set of intersecting facets. A backing layer may be formed over at least a
portion of the exposed diamond layer to enhance the rigidity of the layer when
the substrate is removed.
L'invention concerne, dans un aspect, des procédés de fabrication d'objets tridimensionnels autoportants, soutenus de l'intérieur, dont une surface extérieure présente une pluralité de facettes sécantes. Un sous-ensemble des facettes sécantes comporte une couche de diamant d'épaisseur sensiblement uniforme. La couche de diamant peut être formée par dépôt chimique en phase vapeur (CVD) sur la surface d'un substrat ayant été fabriqué pour constituer un moule définissant le sous-ensemble de facettes sécantes. Une couche renfort peut être formée sur au moins une partie de la couche de diamant exposée pour accroître la rigidité de la couche lorsque le substrat est éliminé.
