A rotary cylindrical mold member and a method for its production, is adapted to be used in a system for molding three-dimensional products from a mass of one or more food starting materials which are suitable for consumption. The method includes preparing at least one mold body forming part of the cylindrical outer surface of the mold member, wherein one or more recessed mold cavities are formed. Subsequently preparing a support member defining one or more fluid channels, recessed in the support surface Heat emitting parts or particles are provided close to the inner surface of the mold body and/or the supporting surface of the support member. Energy is provided to the heat emitting parts or particles, thereby causing the parts or particles to emit heat and thereby locally melt the adjacent porous first plastic and the second plastic to obtain a weld and thereby secure the support member and the mold body to each other.

A method of making 3D printed porous mold or filters are disclosed in which the external surface of the mold/filter is formed by a single printed layer of material. Supporting layers are then laid down on the surface layer in way that creates a porous body that of substantially uniform porosity across the entire mold/filter surface. Use of such porous bodies as screens on molds for the manufacture of molded fiber parts are described as well as general uses as filters having 3D exterior surfaces.

The plurality of pores defined by the frame are distributed in a closest packed state and are interconnected 3-dimensionally through a plurality of connecting passages in a symmetric structure, thus being effective in achieving a maximum porosity of the porous structure. A porous hierarchical structure according to one embodiment of the present invention includes a first porous structure having a plurality of 3-dimensionally interconnected first pores and a second porous structure having a plurality of 3-dimensionally interconnected second pores whose diameter is different from that of the first pores and surrounding and bonded to the first porous structure. A porous hierarchical structure according to a further embodiment of the present invention includes a frame having a plurality of 3-dimensionally interconnected first pores having a diameter in the micrometer range and a plurality of 3-dimensionally interconnected second pores formed around the first pores and whose diameter is smaller than that of the first pores.

According to some aspects, a method is provided of casting an object from a mold, the method comprising obtaining a mold comprising a hollow shell of rigid material, the material comprising a thermoset polymer having a plurality of pores formed therein, providing a metal and/or ceramic slurry into an interior of the mold, exposing at least part of the mold to a low pressure environment so that a net flow of gas is produced from the interior of the mold into the low pressure environment. According to some aspects, a method of forming a porous mold is provided. According to some aspects, a photocurable liquid composition is provided, comprising a liquid photopolymer resin, particles of a solid material, in an amount between 30% and 60% by volume of the composition, and a water-soluble liquid.

The invention is directed to a method of forming a moulded item said method comprising the steps of (a) providing a mould former comprising an indentation having an inner surface and a bottom face and made of plastics and manufactured by a 3-dimensional printing process, said mould former being shaped to form a mould having (i) an indentation corresponding to the desired shape of said moulded item; and (ii) a series of holes extending between the inner surface and the bottom face of the mould former, (b) forming a mould in said mould former from a plastics material; (c) positioning an elongate member in said mould; (d) introducing a volume of liquid into said indentation; (e) positioning a cover over said mould and sealing it thereto; (f) causing said liquid to solidify.
