A method for manufacturing a cosmetic stick having at least two different colored portions includes inserting a pin into at least one mold cavity of a mold body, filling the mold cavity containing the pin with a first cosmetic material of a first color, and then recovering the excess first cosmetic material from a top surface of the mold body. The pin is removed from the mold cavity leaving a void in the mold cavity, and a guard plate is placed over the top surface of the mold body, the guard plate having a hole over the mold cavity. The void in the mold cavity is filled with a second cosmetic material, the second cosmetic material being a second color that is different than the first color. The excess second cosmetic material is then recovered from a top surface of the guard plate.

According to some aspects, techniques are provided for fabricating sinterable metallic parts through the application of directed energy to a build material. In particular, applying energy to a build material comprising a polymer mixed with a metal powder may cause the polymer to form a cohesive structure with the metal powder. As a result, the polymer acts as a “glue” to produce a metallic green part without local melting of the metal. The green part may subsequently be sintered to remove the polymer and produce a fully dense metal part. Optionally, a step of debinding may also be performed prior to, or simultaneously with, sintering.

A method of supporting a cantilevered component mounted to a hub by locating a cassette in proximity to the cantilevered component, the cassette defining a volume for filling with an encapsulant; filling the volume with an encapsulant material; and causing the encapsulant to solidify to the cantilevered component to support the cantilevered component. The cantilevered component is preferably a blade on a bladed disc and the encapsulant provides support to change the vibration response of the blade during a subsequent machining step.

Said invention allowing wax to be melted and maintained at a temperature below the melting point of mold materials such as; but not limited to, filaments commonly used in 3D printing and the like. An object of the invention is to allow users to quickly position and fill custom molds for fabrication processes such as candle and jewelry making.

A manufacturing method of an acoustic coating in an ordered array of interconnected micro-channels intended to receive, on a reception surface, an incident acoustic wave with direction Ac normal to this surface, the method including depositing a sacrificial material on a substrate surface to form a three-dimensional scaffold of filaments, infiltrating at least one part of the three-dimensional scaffold with a thermosetting material, solidifying the thermosetting material to form a solidified material, and removing the sacrificial material from the solidified material to form the ordered array of interconnected micro-channels, the filaments forming by superimposed layers the three-dimensional scaffold being, for a given layer of filaments, oriented in a direction forming, in a plane formed by the layer, a first angle θ relative to the direction Ac of the incident acoustic wave, to confer acoustic properties to the ordered array of interconnected micro-channels and thus form the acoustic coating.

The present invention relates to a method for fabricating a composite construction element using a mould fabricated by a computer-controlled apparatus. The method comprises the steps of fabricating the mould having one or more receiving portions dimensioned to receive one or more respective objects responsive to computer instructions relating to the mould geometry, positioning the one or more objects in respective receiving portions, covering at least a portion of the mould and the one or more objects with settable material, and at least partially curing the settable material, thereby forming the composite construction element having the one or more objects embedded therein.

Subject matter of the present invention is a method of applying coating layers (9) to a substrate (1, 11, 21, 31), wherein the substrate (1, 11, 21, 31) is drawn through a coating chamber (2) containing a pressurized coating agent (3) being liquefied or softened by means of a thermal exposure, wherein the substrate (1, 11, 21, 31) is drawn through a drawing tool (8), wherein the coating agent (3) serves as a lubricant between the drawing tool (8) and a surface of the substrate (8) and wherein at the same time the coating layer (9) is applied to the surface of the substrate (8). Subject matter of the invention is also a corresponding apparatus for applying a coating layer (9) to a substrate (1, 11, 21, 31). By means of the invention coating layers can be applied to a substrate in an efficient and economical way.

Embodiments of the invention are directed to an automated crayon-molding device comprising a crayon-receiving member, an automated heating element, a crayon-melting chamber that is heated to a melting temperature by the automated heating element, and at least one mold. The crayon-receiving member receives the crayon at one end and has a closure mechanism at another held, preventing the crayon from entering in the crayon-melting chamber until it reaches a melting temperature. Once the inside of the crayon-melting chamber, the crayon melts and drips into a mold configured to receive melted wax. Embodiments of the invention also include a method for assembling an automated crayon-molding device and a system for molding crayons that includes a crayon-receiving member, an automated heating element, a crayon-melting chamber, a drawer positioned underneath the crayon-melting chamber, and at least one mold.

The method comprises the following steps: (a) heating at least one cosmetic material; (b) depositing a layer (19) comprising one or a plurality of cosmetic materials heated in step (a); (c) at least partially solidifying the layer (19) by cooling the or each cosmetic material; (d) depositing, on the previous layer (19), an additional layer (19) comprising one or a plurality of cosmetic materials heated in step (a), (e) at least partially solidifying the additional layer (19) by cooling the or each cosmetic material; (f) repeating steps (d) to (e) until a three-dimensional object comprising or forming a structured cosmetic composition is formed.

The cosmetic composition comprised in the three-dimensional object or forming the three-dimensional object is recoverable after solidifying.

3-D printers include an intermediate transfer surface that transfers a layer of material to a platen each time the platen contacts the intermediate transfer surface to successively form a freestanding stack of layers of the material on the platen. A sensor detects the thickness of the layer on the platen after a fusing station fuses the layer. A feedback loop is electrically connected to the sensor and a development station (that includes a photoreceptor, a charging station providing a static charge to the photoreceptor, a laser device exposing the photoreceptor, and a development device supplying the material to the photoreceptor). The development station adjusts the transfer bias of the development device, based on a layer thickness measurement from the sensor through the feedback loop, to control the thickness of subsequent ones of the layers transferred from the intermediate transfer surface to the freestanding stack on the platen.
