The present disclosure is directed to a method for applying a multi-colored coating to a composite structure comprising applying a first co-curable film layer comprising a first color marking to a composite tool, applying a second co-curable film layer comprising a second color marking over the composite tool and at least partially over the first co-curable film layer to create a lay-up of a multi-colored marking, applying a composite structure over the lay-up of the multi-colored marking, and curing the lay-up of the multi-colored marking and the composite structure in a single curing step to create a cured multi-colored coating on the composite structure. A multi-colored coating for marking a composite structure and an aircraft part having a multi-colored marking are also provided.

The method for manufacturing a preform intended for creating a container comprises: - a step 34 of transferring a digital model of the preform that is to be manufactured to an additive manufacturing machine, - a step 36 of producing the preform using the additive manufacturing machine from the transferred digital model, and - a step 38 of cooling the manufactured preform at ambient temperature.

A layer configuration prediction method is provided and includes: a specimen production step of producing multiple specimens by depositing layers of a material in configurations different from each other; a specimen measurement step of performing, on each specimen, measurement to acquire a texture parameter corresponding to a texture; a learning step of causing a computer to perform machine learning of a relation between each of the specimens and the texture parameter; a setting parameter calculation step of calculating a setting parameter corresponding to the texture set to a computer graphics image; and a layer configuration acquisition step of providing the setting parameter as an input to the computer having been caused to perform the machine learning, and acquiring an output representing the layering pattern of layers of the material corresponding to the setting parameter.

A decorative member for a steering wheel which is used for being attached to a resin member formed around a ring core metal of a steering wheel. The decorative member includes a base layer attached to the resin member, a design part arranged on the base layer, and a heater arranged between the design part and the base layer. The base layer may include an extraction part at an intermediate position in a longitudinal direction thereof such that a lead wire connected with the heater is led out of the extraction part.

A shaping device, that shapes a three-dimensional object, includes an ink jet head that discharges an ink to become a material of shaping; and an ink supplying unit that supplies a pre-toned ink, which is the ink toned in advance in accordance with a color to be colored on the 3D object, to the ink jet head, where the ink jet head forms at least one part of the 3D object while coloring the one part with the color of the pre-toned ink by discharging the pre-toned ink.

Methods and systems are disclosed for selecting a print head of a 3D printing machine to apply 3D printing material at one or more positions in a printed 3D object. Embodiments of the present invention may include, in the selection process one or more elements pertaining for example to: geometry of the received 3D model; colorization of the received 3D model; transparency of the received 3D model; properties of the 3D printing material; and constraints of the 3D printing machine.

Described is a process and system for direct printing of a decorative pattern onto an extruded PVC slat. The process includes providing a hot extruded PVC slat; directly contacting a surface of the hot extruded PVC slat with a direct printing cylinder as the slat is moved in a downstream direction, where the cylinder has a pattern with a cell structure that receives ink and rotates to directly apply the ink in the form of the pattern onto the surface of the hot extruded PVC slat. The process also includes controlling a temperature of the direct printing cylinder to inhibit drying of the ink while present on the direct printing cylinder.

This injection-molded article is an injection-molded article using a cellulosic fiber composite resin, including: a resin insert piece including a colorant or a cellulose fiber; a first region formed of the cellulosic fiber composite resin; and a second region formed along a weld line of the cellulosic fiber composite resin extending from the resin insert piece, in which the first region and the second region have different color tones.

The present invention relates to a method of filling different two-kinds of multiple inks into an ink extruding member for a three-dimensional print and a method of three-dimensional printing using the filled ink, and relates to a three-dimensional printing method using multiple inks comprising a step of applying pressure to the retained multiple inks and extruding it into a single extruding port of the extruding part to prepare an ink extruded product and printing the ink extruded product.

According to an example, a three-dimensional (3D) printer may include a delivery device to deposit a light absorbing agent onto selected areas of a layer of build material particles, in which the light absorbing agent absorbs light having wavelengths that are around the ultraviolet wavelength range. The 3D printer may also include a light source to apply light onto the selectively deposited light absorbing agent and the layer of the build material particles, in which the light absorbing agent absorbs light around the ultraviolet wavelength range from the applied light and becomes heated to a temperature that causes the build material particles upon which the light absorbing agent has been deposited to melt and to fuse together following cessation of the application of the light.
