The invention relates to a method for the mass decoration of ceramic products, comprising the following steps: spreading, superposed on one another, a layer (L) of granular or powder material and a decorative layer (3) on a support surface (2); transferring the layer (L) from the support surface (2) to an accumulation belt (T1), contiguous and aligned to the support surface (2), which is located at a lower height than the support surface (2), wherein the accumulation belt (T1) is mobile in advancement at a speed that is different from the advancement speed of the support surface (2), so that a variation in the thickness and longitudinal extension of the layer (L) is produced; pressing the layer (L) and the decorative layer (3).

A method of fabricating a composite material part includes placing a fiber texture in a mold including in its bottom portion a porous material part on which a first face of the texture rests, injecting a liquid under pressure into the fiber texture, the liquid containing a powder of refractory ceramic particles, and draining through the porous material part the liquid that has passed through the fiber texture, while retaining the powder of refractory ceramic particles inside said texture by the porous material part. A perforated rigid element is interposed between the bottom of the mold and the porous material part.

Provided is a three-dimensional shaped article with relatively high strength and relatively high accuracy. A sintering and shaping method includes: a shaping layer forming process of forming a shaping layer by using a sintering and shaping material in which inorganic particles are included; a process of applying a liquid binding agent, in which a thermoplastic resin and inorganic particles are included, to a desired region of the shaping layer; a process of curing the liquid binding agent, which is applied, to form a shaping cross-sectional layer (shaping portion); a process of removing a region (non-shaping portion) of the shaping layer to which the liquid binding agent is not applied; and a process of heating the shaping cross-sectional layer that is laminated for a sintering treatment.

A mould liner for a fabrication assembly is disclosed. The fabrication assembly is for fabricating an elongate concrete article in a substantially upright orientation and includes a core assembly and an outer mould assembly defining a mould cavity between the core assembly and an inner moulding surface of the outer mould assembly with the outer mould assembly being separable following casting of the elongate concrete article to strip the outer mould assembly from the elongate concrete article. The mould liner during casting forms an intermediate layer between the inner moulding surface of the outer mould assembly and the elongate concrete article being cast, wherein on stripping of the core and outer mould assemblies following casting, the mould liner is adapted to form an outer containment layer to the elongate concrete article.

A lightweight and strong tile constructed of a composition of cement, cellulous, perlite powder iron oxide and water is disclosed. The cellulous may include recycled paper products such as paper and cardboard that may be shredded. Excess water is removed by a vacuum and the composition is pressed to form a tile.

In an example of a three-dimensional (3D) printing method, a ceramic build material is applied. A liquid functional material, including an anionically stabilized susceptor material, is applied to at least a portion of the ceramic build material. A sintering aid/fixer fluid, including a cationically stabilized amphoteric alumina particulate material, is applied to the at least the portion of the ceramic build material. The applied anionically stabilized susceptor material and the applied cationically stabilized amphoteric alumina particulate material react to immobilize the anionically stabilized susceptor material, thereby patterning the at least the portion of the ceramic build material.

An apparatus for fabricating a three-dimensional object includes a fabrication stage and a flattener. A fabrication layer in which powder particles are bound together is formed layer-by-layer on the fabrication stage. The flattener relatively moves in a moving direction along a stage surface of the fabrication stage and flattens a surface of powder on the fabrication stage to form a powder layer. The fabrication stage and the flattener are arranged to be relatively movable in a height direction. In formation of the powder layer on the fabrication layer formed on the fabrication stage, the apparatus performs an operation to increase a distance between the flattener and the fabrication stage in the height direction when the flattener moves to a position near an edge of the fabrication layer in the moving direction.

Provided is a three-dimensional shaped article with relatively high strength and relatively high accuracy. A sintering and shaping method includes: a shaping layer forming process of forming a shaping layer (5) by using a sintering and shaping material in which inorganic particles (2a) are included; a process of applying a liquid binding agent (8), in which inorganic particles (8a) are included, to a desired region of the shaping layer (5); a process of curing the liquid binding agent (8), which is applied, to form a shaping cross-sectional layer (shaping portion (5a)); a process of removing a region (non-shaping portion (5b)) of the shaping layer (5) to which the liquid binding agent (8) is not applied; and a process of heating the shaping cross-sectional layer that is laminated for a sintering treatment.

A process for manufacturing a composite material part includes formation of a fibrous texture from refractory ceramic fibres, placement of the fibrous texture in a mould with interposition of a filtration layer between the fibrous texture and a discharge port, the filtration layer including a partially densified fibrous structure, pressure injection of a slurry containing a powder of refractory ceramic particles into the fibrous texture, drainage by the filtration layer of the slurry solvent having passed through the fibrous texture and retention of the powder of refractory ceramic particles within the texture by the filtration layer to obtain a fibrous preform including the fibrous texture filled with refractory ceramic particles and the filtration layer, heat treatment of the refractory ceramic particles present in the fibrous texture of the preform to form a composite material part including the fibrous texture densified by a refractory ceramic matrix and the filtration layer.
