A decorative composite body includes a glass body and a plastic partly enclosing the glass body, wherein part of the surface of the glass body is arranged on the outside of the decorative composite body, wherein at least two adjacent glass and plastic areas arranged on the outside of the composite body are ground in the composite state, wherein areas of the glass body adjacent to the plastic are at least partly mirrored.

In current systems, only one consumer can personalize a product using a single session or at a single device (e.g., a computer, mobile device). In an embodiment, a method includes providing, at a user device via a network, a user interface displaying a three-dimensional (3D) model of a consumer product selected by a user. The method further includes customizing the 3D model of the consumer product based on selections and manipulations of the consumer product received at the provided user interface from at least two users. The method further includes, responsive to finalization of the customized 3D model by one of the users, submitting the customized 3D model for 3D printing. In this manner, multiple people can collaborate to create a single 3D printed product.

A method for manufacturing a play-of-color article includes the steps of: (a) providing a first mixture that contains a solvent and a plurality of functionalized colloidal particles; (b) replacing the solvent of the first mixture with a polymer solution that contains polymers, thereby obtaining a second mixture; (c) adding an initiator to the second mixture to obtain a third mixture, followed by injecting the third mixture into a mold and disturbing the third mixture, so that the third mixture is formed with a pattern; (d) leaving the third mixture to stand, so as to allow the functionalized colloidal particles therein to self-assemble to form a crystalline arrangement, thereby obtaining a fourth mixture; and (e) subjecting the polymers in the fourth mixture to a cross-linking reaction, thereby obtaining the play-of-color article. A play-of-color article manufactured by the method, and a play-of-color product including the play-of-color article are also provided.

A method for preparing a composite body (1) comprising a support body (2) and at least one decorative element (3), preferably a gemstone (3a, 3b), the support body (2) comprising a thermoplastic material, the method being characterized by the steps of: arranging the decorative element (3) on the support body (2), heating the support body (2), pressing the decorative element (3) into the support body (2) by using a stamp (4) consisting of an elastically deformable material, the material of the stamp (4) being selected from the group of elastomers.
