Abstract: A method for manufacturing includes coating a substrate (22) with a matrix (28) containing a material to be patterned on the substrate. A pattern (42) is fixed in the matrix by directing an energy beam to impinge on the coated substrate so as to fix the pattern in the matrix without fully sintering the pattern. The matrix remaining on the substrate outside the fixed pattern is removed, and after removing the matrix, the material in the pattern is sintered.

Abstract: The method comprises sequentially forming a plurality of layers in a configured pattern corresponding to the shape of the object, thereby forming the object. The formation of each layer comprises dispensing at least one uncured building material, and at least partially curing the uncured building material, wherein for at least one layer, the curing is initiated at least t seconds after commencement of curing of a layer immediately preceding that layer. The t parameter is longer than the number of seconds required for the formation of the layer.

Abstract: A therapeutic, cosmetic or cosmeceutic composition for topical application, capable of stabilizing an active ingredient and delivering the active ingredient, comprising a plurality of microcapsules having a core-shell structure. The microcapsules have a diameter of approximately 0.1 to 100 micron. The core of each microcapsule includes at least one active ingredient, and is encapsulated within a microcapsular shell. The shell is comprised of at least one inorganic polymer obtained by a sol-gel process, and the shell protects the active ingredient before topical application and is designed to release the active ingredient from the microcapsules following application. The composition is useful in encapsulating active ingredients, such as benzoyl peroxide, that are unstable in other formulation, or are irritating to the skin.
