A transaction card has a substructure consisting at least in part of a layer of fibrous material, such as carbon fiber strands or filaments, arranged in a pre-selected pattern, such as a weave pattern, that is at least partially enclosed by a transparent plastic film. A sheet is laminated on each of two opposing faces of the substructure to form a transaction card core. One or both of the sheets laminated on the opposing faces of the substructure is also made of a transparent material, and one or both of the two opposing faces of the transaction card core can be printed. An over-laminate film, such as a transparent polyvinyl chloride plastic film, can be laminated on each of two opposing faces of the transaction card core.

A method for producing a pattern in relief in a thin plastic card, includes the following steps: producing a stack of layers including, in the following order: a transparent layer, a special layer, a black surface, and a substrate layer, and drawing the pattern by a laser through the transparent layer.

Embodiments describe constructing game-related objects through additive manufacturing systems. At least one construction configuration for building a game-related object is advanced at least partly due to at least one game task result being attained by a user and/or due to when an object is constructed and/or arranged to be built. Several embodiments demonstrate select game task results leading to determined construction configurations instead of alternative construction configurations, causing, for instance, a differing design, complexity, function, and/or number of constructed object portions. Game task results in certain embodiments lead to multiple distinct portions of one or more objects being constructed concurrently and/or successively, at one or more locations. Selected methods and systems disclose objects constructed as awards, puzzles, other assembly challenges, educational challenges, wagering elements, electronic game elements, in multiple inseparable portions, and/or for other entertainment purposes.

In example implementations, a method is disclosed. The method includes dispensing a layer of an optically clear build material, dispensing a fusing agent onto a first portion of the layer of the optically clear build material, dispensing an invisible fluorescence compound on a second portion of the layer of the optically clear build material, and applying ultraviolet (UV) light to the layer to fuse the first portion and the second portion of the optically clear build material that received the fusing agent and the invisible fluorescence compound. The invisible fluorescence compound is to print an embedded feature in the layer that is invisible under a first light and visible under a second light.

A method for producing a film for a card-shaped data carrier, includes the following steps: providing at least one first material in an extruder of an extrusion apparatus; heating the first material to form a melt; extruding the melt through a nozzle outlet gap of the extrusion apparatus; conveying the extruded melt on a roller arrangement that is adjacent to the nozzle outlet gap and includes at least one cooling roller; providing at least one transfer film; supplying the transfer film to the extruded melt on the cooling roller is so the security element contacts a surface of the extruded melt on the surface of the transfer film; transferring the security element from the surface of the transfer film onto the surface of the extruded melt; cooling the extruded melt comprising the security element to form the film.
