The present disclosure relates to a ceramic tile decorated with dry particles to give a three-dimensional pattern and a manufacturing method thereof. The manufacturing method comprises the steps of A: glazing a surface of a green body with a ground coat; B: decorating a surface of the ground coat of the green body to form a pattern; C: drying the green body; D: embellishing the green body with dry particles; E: spraying a protective glaze on the surface of the green body; and F: firing the green body after the green body is sprayed with the protective glaze of step E to produce the ceramic tile decorated with dry particles. The manufacturing method can make the ceramic tile produced have a clear pattern, distinct layers, low glaze glossiness, a good non-slip effect, an obvious sense of dry particles, a strong three-dimensional effect, rich colors, and stable properties.

A machine for decorating items with granular materials, including at least one transportation device, adapted to convey the items to be decorated along a feed direction (A) and a feed orientation (V), and at least one decoration assembly of the items (P), supported above the transportation device and adapted to deposit, on the surface of each item (P), a certain quantity of granular material (M) so as to achieve a determined aesthetic effect. The decoration assembly includes a first module for dispensing adhesive fluid, of the type provided with heads with dispensing nozzles, adapted to dispense at least a first layer of adhesive fluid on the surface of the item (P) to be decorated according to a specific decorative pattern or motif, and at least one supplying device of granular material.

A machine and method for the surface treatment of a base ceramic article having at least one surface to be treated; wherein a first printing assembly applies a first layer of adhesive material on at least part of the surface to be treated; a first depositing assembly deposits a second layer of powder material on at least part of the first layer so as to remain stuck to the first layer; and a second printing assembly applies a third layer, which comprises (in particular, consisting of) an adhesive and/or covering material, on at least part of the second layer.

A machine for the digital decoration of products with granular materials and the like, comprises: a basic frame; at least one supporting surface for supporting at least one product to be decorated associated with the basic frame; at least a first digital printing head adapted to apply at least a first layer of fluid adhesive material on the surface of the product to be decorated; a deposition component/device/unit/circuit or the like of a granular material on the first layer of adhesive material; a removal component/device/unit/circuit or the like of the excess granular material; at least a second digital printing head adapted to apply at least a second layer of fluid adhesive material on top of the granular material, the second printing head being positioned between the deposition component/device/unit/circuit or the like and the removal component/device/unit/circuit or the like.

A method and machine for the surface decoration of a basic article comprising ceramic material and having a surface and a printing assembly applies an adhesive material digitally and selectively onto a defined area of the surface. A treatment assembly deposits a powder material digitally and selectively in the defined area, and the powder material in excess arranged on the basic article is removed.

The procedure for tile (1) decoration comprises the following phases: providing a ceramic article (2) in raw material, provided with a flat surface to be decorated (3); depositing thoroughly a decorative powder (4) on the flat surface to be decorated (3); fixing the decorative powder (4) to the flat surface to be decorated (3) by means of radiation-emitting fixing means (5), according to a predefined drawing (6); removing the decorative powder (4) in excess to obtain a decorated ceramic article (7); firing the decorated ceramic article (7) in a kiln to obtain a tile (1).

A tooling for infiltrating a slurry into a textile preform includes a mold which includes an impregnation chamber including, on one of its face, an element for filtering a liquid phase of the slurry intended to receive a first face of a textile preform, the impregnation chamber being closed by a counter-mold located facing the filtration element; and an output vent present on the mold and configured to eliminate a filtrate of the filtration element at an elimination pressure, wherein the tooling also includes a circulation system for a slurry including an input port and an output port, the circulation system being configured to circulate the slurry in the impregnation chamber from the input port to the output port at a circulation pressure greater than the elimination pressure.

A method and machine for the surface decoration of a basic article comprising ceramic material and having a surface and a printing assembly applies an adhesive material digitally and selectively onto a defined area of the surface. A treatment assembly deposits a powder material digitally and selectively in the defined area, and the powder material in excess arranged on the basic article is removed.

A powder-based additive manufacturing installation (10) comprises a powder layering device (14) that can be displaced along a path linking a start zone (A) and an end zone (B). The layering device (14) comprises powder smoothing means (35) for depositing powder in a powder deposition zone (P) situated between the start zone (A) and the end zone (B). The installation furthermore comprises a cleaning device (60) situated on the path of the layering device (14), the cleaning device (60) comprising a brushing device (62) for brushing at least one surface of the powder smoothing means (35).
