The invention relates to a device for producing products having individual geometries, comprising a substrate carrier device, a material application device for applying material, preferably above the substrate carrier device, which material application device can be moved relative to the substrate carrier device, and a control device which is coupled to the material application device for signaling. According to the invention, the material application device is coupled to an input interface for signaling and for selection of a first or a second application mode, the control device and the application device being designed such as to produce, in the first application mode, a three-dimensional product on the surface of a substrate plate by way of an additive production method, said substrate plate being connected to the substrate carrier device. According to the additive production method, a curable material is applied in consecutive layers, one or more predetermined regions are selectively cured after or during each application of a layer, the predetermined regions being bonded to one or more regions of the underlying layer. The predetermined region(s) is/are predetermined by a cross-section geometry of the product in the respective layer and is/are stored in the control device, and the curable material is applied in a plurality of consecutive layers to produce the three-dimensional product. The control device and the application device are further designed such that in the second mode of application one or more colors are applied to predetermined regions of a print substrate material connected to the substrate carrier device to produce a monochrome or polychrome print.

The present disclosure is related to a method for manufacturing slabs of artificial agglomerated stone comprising: depositing a first layer (1.1) of a first mixture (M.sub.1) onto a surface (2), wherein the first layer having a first thickness h.sub.1, creating at least one cavity (3), having a width w.sub.i and a length L.sub.i, in the first layer (1.1) of first mixture (M.sub.1), depositing a second mixture (M.sub.2) into the at least one cavity (3) of the first layer (1.1), forming a second layer (1.2) by depositing the first and second mixtures, and the second layer having a second thickness h.sub.2, compacting and hardening the second layer (1.2),
wherein the method further comprises after step c) and before step d), inserting a first tool (5) at least partially into the second thickness h.sub.2 of the second layer (1.2), and actuating the first tool (5) wherein the first tool (5) is configured to stir the first wall portion (4.1) while not stirring the second wall portion (4.2).

[Problem] To provide: a model component having stable quality and having gradation; and a production method therefor [Solution]A model component having: a first layer formed using a first material having a first color; and a second layer that covers at least part of the first layer and comprises a second material having a second color that is different from the first color. The second layer includes a region having a thickness in at least one section that is less than other sections. The region includes a section in which the first layer is exposed to the surface of the second layer.

A mixed resin ejection unit is configured to eject a mixed resin obtained by mixing the coloring material resins supplied from the plurality of material resin supply units. The plurality of material resin supply units being configured to supply the coloring material resins of different colors to the mixed resin ejection unit. The method includes controlling the amounts of the coloring material resins to be supplied from each of the plurality of material resin supply units to the mixed resin ejection unit, thereby adjusting a color of the mixed resin that is to be ejected by the mixed resin ejection unit.

A color 3D printing method, a printing apparatus and a terminal device. The printing method includes acquiring an original three-dimensional model of an object to be printed; performing shell processing to the original three-dimensional model to generate an inner model and an outer model of the original three-dimensional model; performing slicing processing to the inner model and the outer model to generate multiple printing data corresponding one-to-one with each printing layer, the printing data including structural data representing the inner model in a printing layer, color data representing the outer model in the printing layer, and structural data representing the outer model in the printing layer; printing the object to be printed according to the printing data. The present method can distinguish between a background color and a surface color of the original three-dimensional model in a slice image, avoiding phenomena of not printing or misprinting.
