A method for producing a mold segment component of a vulcanizing mold for a pneumatic vehicle tire for forming at least one profile block or a region structured in a block-like manner of an altogether curved tread, with a tread outer surface, which mold segment component is built up by means of an additive process, such as selective laser melting, by layer-by-layer planar application and melting of a metal powder on a planar building plate (10) together with a bottom part (7b) and mold elements, such as lamellae (4) and/or microlamellae (11) and/or ribs and/or regions of ribs, wherein mold elements delimit or run around mutually adjacent mold area elements (12) of the bottom part (7b) which have outer surfaces (12a) forming a region of the tread outer surface.In the additive build-up operation, the mold area elements (12) are each additively built up with a unitary planar outer surface (12a) or with two to three planar outer surfaces (12a) running in a stepped manner in relation to one another, wherein all of the outer surfaces (12a) of the mold area elements (12) run parallel to one another and, with respect to the building plate (10), are surfaces at different levels such that the mutual arrangement of the outer surfaces (12a) of the mold area elements (12) largely approximates to the curvature of the region to be formed of the tread outer surface.
