The present invention provides a flexible mat with fluid conduit, methods of manufacture thereof and apparatus for the manufacture thereof. In an embodiment, the mat comprises a base layer, one or more fluid conduits and a thermoplastic bonding tape that attaches the fluid conduits to the base layer. The base layer can be a textile fabric, mesh or netting, or a flat flexible sheet. The base layer is preferably also formed of a thermoplastic layer. The fluid conduits can carry heated or cooled fluid, such as water, that can be used for heating or cooling an environment in which the device is deployed. For example, the device can be used for heating or cooling in a greenhouse environment. The fluid conduits can additionally or alternatively carry irrigation fluids, such as water or treated water, for irrigating plants and crops. The fluid conduits can additionally or alternatively carry gases, such as carbon dioxide (CO.sub.2) or carbon dioxide mixed with other gasses, for treating plants and crops.

The present invention relates to a method for manufacturing a 3D item (100) by means of fused deposition modelling (FDM), the method comprising the steps of: a) providing a shell component (5) comprising a thermoplastic 3D printable shell material having a shell melting temperature (Tms) and/or a shell glass transition temperature (Tgs); b) providing a core component (2) comprising a plurality of thermally conductive wires (3) and a flexible mantle (4) enclosing the plurality of thermally conductive wires (3); c) feeding the shell component (5) into a nozzle (6) of a 3D printer, the nozzle (6) having a nozzle temperature (Tn) being equal to or greater than the shell melting temperature (Tms) and/or the shell glass transition temperature (Tgs); d) a layer-wise depositing of the 3D printable shell material and the core component (2) to provide the 3D item (100) comprising a core-shell layer (100) of 3D printed material, wherein the 3D printed material comprises a core (102) comprising the core component, and shell (105) comprising 3D printed shell material, wherein the shell (105) at least partly encloses the core (102).

An aerosol-generating article comprises an aerosol-cooling element. The aerosol-cooling element comprises an extruded member having a length, and comprising an external surface defining the perimeter of a cross section perpendicular to the length of the extruded member; and an internal surface defining one or more pathways through the length of the extruded member. The internal surface or the external surface or both the internal surface and the external surface comprise surface irregularities.

A method for manufacturing an arrangement for the transport of media includes a base body formed as a blow-molded part and at least one functional element, in which a preform consisting of polymeric material and at least one functional element are provided and arranged in a blow mold, wherein the base body is formed from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element, wherein the base body is formed from the preform between the first mold element and the second mold element, wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed.

An aerosol-generating article comprises an aerosol-cooling element. The aerosol-cooling element comprises an extruded member (100) having a length (108), and comprising an external surface (104) defining the perimeter of a cross section perpendicular to the length of the extruded member; and an internal surface (102) defining one or more pathways (110) through the length of the extruded member. The internal surface or the external surface or both the internal surface and the external surface comprise surface irregularities.
