    摘要： A pressing method for pressing ceramic slabs, comprising the following steps: spreading a layer (1) of granular or powdered material onto a pressing plane (2), wherein the layer (1) comprises at least a first zone (11), with a prefixed area and border, made of a granular or powdered primary material, and at least a second zone (12), with a prefixed area and border, made of a granular or powdered secondary material different from the primary material; pressing the layer (1) using a press (P); separating at least a main portion (10) of the first zone (11) from the second zone (12).

    摘要： A method is provided for providing a set of ingredients for manufacturing of a dental prosthesis covering. The method comprises receiving a background colour value providing information on a colour of a background substrate on which the prosthesis is to be provided, receiving an appearance colour value providing information on an appearance colour of the prosthesis and receiving a thickness value providing information on a thickness of the dental prosthesis covering. In an electronic memory, a first ingredient record is looked up comprising first ingredient value, based on the measured background value and the measured appearance colour value. The first ingredient values are adjusted in an electronic processor adjusted based on the thickness value and through electronic output means, the adjusted ingredient data is provided. By adjusting ingredients for thickness, a more natural appearance may be achieved.

    摘要： An abnormality determination device for an additive manufacturing apparatus for building a part having three-dimensional shape by repeatedly forming a membrane of raw material and forming a cured layer having two-dimensional shape, the membrane formed by a blade in a build area, the raw material including ceramic particles and photocurable resin, the cured layer formed by irradiating the membrane with light in the build area, the abnormality determination device includes a controller configured to perform abnormality determination based on an image captured by an image sensor, the controller is configured to acquire the image of the membrane captured by the image sensor, detect a linear abnormal portion appearing in the membrane as a line extending along a movement direction of the blade based on the acquired image of the membrane, and determine that layering fault has occurred in response to detection of the linear abnormal portion.

    摘要： The present disclosure relates generally to methods of analysing and manufacturing gypsum panels, for example, suitable for use as building surface products. The present disclosure relates more particularly to a method of forming a gypsum panel. The method includes forming a porous slurry layer on a receiving surface using a plurality of operating parameters, and allowing the porous slurry layer to set to form a gypsum core of a gypsum panel. The panel is then cut to form a cut surface that extends through the gypsum core, and an image of a region of the cut surface is captured. The image is analysed to identify bubbles intersecting the cut surface. A measure of bubble contact in the gypsum core is then calculated from the identified bubbles in the image. Based on the measure of bubble contact, an operating parameter used for forming the porous slurry layer is modified.
