A method of molding a metalized composite part. The method comprises: introducing particles comprising at least one metal into a gas stream; directing the gas stream toward a surface of a thermoplastic composite part, thereby depositing a metal layer on the composite part to form a metallized composite part; and molding the metallized composite part to introduce a bend without delamination of the metal layer from the metallized composite part.

Ways of preparing a partially crystalline polycarbonate powder are provided that include dissolving an amorphous polycarbonate in a polar aprotic solvent to form a first solution of solubilized polycarbonate at a first temperature. The first solution is then cooled to a second temperature, the second temperature being lower than the first temperature, where a portion of the solubilized polycarbonate precipitates from the first solution to form a second solution including the partially crystalline polycarbonate powder. Certain partially crystalline polycarbonate powders resulting from such methods are particularly useful in additive manufacturing processes, including powder bed fusion processes.

The present disclosure provides three-dimensional (3D) printing methods, apparatuses, software and systems for a step and repeat energy irradiation process; controlling material characteristics and/or deformation of the 3D object; reducing deformation in a printed 3D object; and planarizing a material bed.

A method of additive manufacture is disclosed. The method may include creating, by a 3D printer contained within an enclosure, a part having a weight greater than or equal to 2,000 kilograms. A gas management system may maintain gaseous oxygen within the enclosure atmospheric level. In some embodiments, a wheeled vehicle may transport the part from inside the enclosure, through an airlock, as the airlock operates to buffer between a gaseous environment within the enclosure and a gaseous environment outside the enclosure, and to a location exterior to both the enclosure and the airlock.

The subject of the invention is a support panel with cellular core structure and the manufacturing process for the support panel with cellular core structure which solve the technical problems of: facilitating the manufacture of the product, ensuring compactness of individual panels and manufacturing support panels with cellular structure (1) in a single step. The support plate with cellular structure (1) comprises at least the upper solid surface (2), the lower solid surface (3) and the cellular structure (4), whereby all of these components are made of any thermoplastic material; however, all of the components are made of the same material. The cellular structure (4) is constructed with energy directors (5) to prevent spacing between the cellular structure (4), the upper solid surface (2) and the lower solid surface (3). The pre-formed cellular core (4) is placed on the levelled thermoplastic material used to form the lower solid surface, after which the material is applied over the cellular core (4) up to the depth required to form the lateral surfaces and the upper solid surface (2). After heating and pressing the material, the support panel with cellular structure (1) is cooled under pressure, and then it is removed from the press mould.

Provided is a three-dimensional object formation method for forming a three-dimensional object by at least repeating: forming a powder material layer using a powder material for three-dimensional object formation containing a base material coated with an organic material; and hardening a predetermined region of the powder material layer by delivering a hardening liquid to the powder material layer formed in the formation of a powder material layer, where the hardening liquid contains a cross-linking agent cross-linkable with the organic material.

The invention relates to a sound protection panel for cladding a wall of an automotive vehicle, the panel includes a mass-spring system.
