Moulding tool, for compression moulding and or in mould foaming of automotive trim parts, comprising at least one mould having a 3D shaped cavity, characterised in that the mould part comprises a thermoset resin binder matrix with particulates bound within the matrix.

A system is used for additively manufacturing propellant elements, such as for rocket motors, includes partially curing a propellant mixture before extruding or otherwise dispensing the material, such that the extruded propellant material is deposited on the element in a partially-cured state. The curing process for the partially-cured extruded material may be completed shortly after the material is put into place, for example by the material being heated at or above its cure temperature, such that it finishes curing before it fully cools. The propellant material may be prepared by first mixing together, a fuel, an oxidizer, and a binder, such as in an acoustic mixer. After that mixing a curative may be added to the mixture. The propellant mixture may then be directed to an extruder (or other dispenser), in which the mixture is heated to or above a cure temperature prior to the deposition, and then deposited.

A nozzle assembly comprising a housing, a nozzle disposed in the housing and connected to an ink supply part, a first coil, which is disposed in the housing, for generating a magnetic field when a power source is applied, a second coil disposed in the housing, disposed so as to surround the nozzle and the first coil and generating a magnetic field when a power source is applied, provided that at least one of the magnetic field effective area and the magnetic field intensity is different from that of the first coil, and a lift part for lifting the nozzle and the first and second coils, respectively, so as to be positioned in the housing or exposed to the outside of the housing.

The present disclosure provides methods and systems for printing a three-dimensional (3D) object. The methods may comprise providing, adjacent to a build surface, a film comprising a polymeric precursor. A sensor may be used to determine a profile of the film. The profile may be indicative of a quality of the film. If the profile meets a quality threshold, at least a portion of the film may be exposed to light to initiate formation of a polymeric material from the polymeric precursor, thereby printing at least a portion of the 3D object.

A method is provided for fabricating a unitary element, such as an exercise weight, including a composite material. The method includes providing a plurality of solid fragments including at least one non-thermoplastic material. The method further includes providing a plurality of solid particles including at least one thermoplastic polymer and/or elastomer material, at least 75% of the solid fragments having sizes in a fragment size range from zero to 32 millimeters and at least 75% of the solid particles having sizes in a particle size range from zero to 1.5 millimeters. The method further includes forming a mixture of the plurality of solid fragments and the plurality of solid particles, the mixture including 90% to 20% of the fragments by volume and 10% to 80% of the particles by volume. The method further includes molding or extruding the mixture into a unitary element through the application of heat and/or pressure.

A method for producing a component from two or more sub-components includes the steps of: producing each of the sub-components using an additive manufacturing process in which a resin, which is radiant-energy-curable, is partially cured using a selective application of radiant energy, wherein each sub-component includes a joint surface in which the resin is partially cured which is cured to a lesser degree than the remainder of the respective sub-component, so as to leave the joint surfaces in a condition suitable for bonding; assembling the sub-components with their respective joint surfaces in mutual contact; and performing a secondary cure of the partially-cured resin at the joint surfaces using an application of radiant energy, so as to further cure the partially-cured resin and bond the sub-components to each other, thereby forming the component.

A shaped article is provided. The shaped article includes a light reflective layer, a decorative layer, and a first transparent layer. The light reflective layer is being provided from an ink having light reflectiveness. The first transparent layer is being provided from a transparent ink. The decorative layer is disposed on an outer side of the light reflective layer. The first transparent layer is disposed on an outer side of the decorative layer.

A method of producing an anisotropic conductive film having a three-layer structure including a first connection layer, a second connection layer, and a third connection layer. The connection layers are each formed mainly of an insulating resin. The first connection layer is held between the second connection layer and the third connection layer.

The disclosed concept relates to compositions and methods for the manufacture of electrically resistive, thermally conductive electrical switching apparatus. The composition includes a polymer component and a nanofiber component. The thermal conductivity of the nanofiber component is higher than the thermal conductivity of the polymer component such that the electrical switching apparatus which includes the composition of the disclosed concept has improved heat dissipation as compared to an electrical switching apparatus constructed of the polymer component in the absence of the nanofiber component. Further, the disclosed concept relates to methods of lowering the internal temperature of an electrically resistive, thermally conductive electrical switching apparatus by forming the internals of the apparatus, e.g., circuit breakers, and/or the enclosure from the composition of the disclosed concept.
