Abstract

Method of manufacturing a three-dimensional object (22) by means of additive manufacturing as well as to a corresponding system for carrying out the method and a dispensing head for use in the method. The three-dimensional object (22) comprises a three-dimensional component (21). The method comprises providing a substrate (20, 20"), and successively forming on the substrate (20, 20") a plurality of layers (23, 23'), wherein each layer is formed in a pattern corresponding to a three-dimensional component (21) being manufactured and wherein each layer (23, 23') is formed by dispensing a curable material from a nozzle (5, 5') of a dispensing head (4, 4', 4") and subsequently curing the curable material (8). The three-dimensional object (22) is constituted by the combination of the substrate (20, 20") and the three-dimensional component (21), wherein the substrate (20, 20") has a non-planar surface portion and the three-dimensional component (21) is formed at least in part on the non-planar surface portion in such a manner that it is fixedly secured to the substrate (20, 20"). During forming of at least one of the layers (23, 23') and/or between forming of at least two adjacent ones of the layers (23, 23') a relative movement between the substrate (20, 20") and the dispensing head (4, 4', 4'') is effected such that in a substrate coordinate system the dispensing head (4, 4', 4") moves along a non-linear path over the non-planar surface portion.
