Abstract: A mold segment (10) for forming a tire is provided that has a sipe element (14) with first and second ends. A first side face (20) is oppositely disposed from a second side face (22) in a width direction, and a bottom is oppositely disposed from a top in a height direction. The sipe element has a projection (30) that extends from the first side face. A mold segment base (32) made of a material that is more flexible than material making up the sipe element (14) is present. The mold segment base receives the sipe element such that the bottom of the sipe element is located inside of the mold segment base and the top of the sipe element is located outside of the mold segment base. The mold segment base defines a cavity (34), and the projection (30) is located inside of the cavity (34). The mold segment (10) is used for forming a production mold segment (68) that ultimately molds a green tire into a cured tire (12).

Abstract: Process for additive manufacturing of at least one part. At least one layer of powder is deposited on a working surface using a layering device for distributing the powder mobile in translation along the surface and at least partly fusing the layer deposited using a beam of energy. The depositing and fusing steps are repeated in order to form the part by stacking of fused layers. The distribution component of the layering device is mobile in a direction substantially parallel to the direction of the length of each fused layer of the part. The depositing and fusing steps are repeated in order to form the part so that the length of the part extends along a direction substantially parallel to the stacking direction of the fused layers and so that the head of the part is oriented substantially perpendicular to the working surface.
