Abstract: The present invention relates to a process for the production of a composite article comprising a structured porous body (PB) and a particle foam (PF), wherein the provided structured porous body (PB) is inserted into a mould (M) and the mould (M) is filled with expanded foam beads (EFB) so that the expanded foam beads (EFB) are in contact with each other and the structured porous body (PB) is at least partially in contact with the expanded foam beads (EFB). Then, the expanded foam beads (EFB) are thermally welded, wherein the particle foam (PF) is built and the composite article is obtained. Moreover, the present invention relates to a composite article obtained by this process, as well as to a composite article comprising a structured porous body (PB) and a particle foam (PF). The present invention further relates to the use of the inventive composite articles in the shoe industry, in the sports and leisure sector, in vehicle construction, in the medical sector, in mechanical engineering and in the logistics sector. Furthermore, the present invention relates to a composite article comprising a structured porous body (PB) and a foam (F), wherein the structured porous body (PB) and the foam (F) comprise the same polymer (P).

Abstract: The invention refers to an apparatus (110) for generating a library of physical properties of structured porous bodies and use the library to generate a control file for additive manufacturing of physical components comprising the structural porous bodies. The apparatus comprises a providing unit (111) for providing structural representations for a plurality of structured porous bodies, wherein a structural representation is indicative of a structure of a structured porous body. A providing unit (112) is adapted to provide a material model, wherein the material model is indicative of a response of a material to one or more external physical influences. A determination unit (113) is adapted to determine physical properties for the structured porous bodies, wherein a physical property for a structured porous body is determined based on the structural representation of the structured porous body and the material model. Further, a generation unit (114) is adapted to generate a library based on the physical properties determined for the structured porous bodies. The library is used to generate a control file to be used by a 3D printer for manufacturing the product.

Abstract: The present invention relates to a high-heeled shoe comprising an insert (E) and a base body (G), wherein the base body (G) is produced as a single part via a 3D printing process. The insert (E) comprises a surface (EF) that has an upper side (EO) and a lower side (EU), wherein a heel (A) is formed on the lower side (EU). The base body (G) comprises a base surface (F) and an inner flap (I), wherein the base surface (F) has an upper side (FO), a lower side (FU) and a first cavity (H1), and the inner flap (I) has an upper side (IO) and a lower side (IU), wherein the lower side (IU) of the inner flap (I) is joined with the upper side (FO) of the base surface (F) of the base body (G) such that, between the lower side (IU), the upper side (FO) and the first cavity (H1), a second cavity (H2) is formed which forms an overall cavity (HG) with the first cavity (H1), wherein the overall cavity (HG) essentially corresponds to the shape of the insert (E). The insert (E) is positioned in the overall cavity (HG) such that the lower side (EU) of the surface (EF) of the insert (E) is completely contacted with the upper side (FO) of the base surface (F) of the base body (G), and the lower side (IU) of the inner flap (I) completely covers the upper side (EO) of the surface (EF) of the insert (E). The present invention furthermore relates to a process for producing the high-heeled shoe and to the use of an inner flap (I) for completely covering the upper side (EO) of the surface (EF) of an insert (E) in a high-heeled shoe.
