Embodiment Construction

[0017] The present invention generally relates to a method and equipment for additive manufacturing of a three-dimensional object. The method and equipment are configured to construct a forming mold layer by layer through a set of geometric shapes corresponding to a set of cross-sections, and to provide raw materials to the interior for processing. To shape the three-dimensional object. The forming mold or part of the forming mold presents a closed-around structure during its construction, and thus has a cavity formed therein, which can be used to shape a three-dimensional object with an outer surface and an inner surface. In this way, after at least one layer is built up in the forming mold, raw materials can be added to it for processing. The construction of the forming mold and the object continues until the construction of the three-dimensional object is completed.

[0018] The molding die is more suitable for building a thin-walled shell-shaped structure to reduce the mater...

Abstract

The present invention relates to an additive manufacturing method and apparatus that is configured to construct a mold in additive layers, and a three-dimensional object therein in layers equal to orthicker than the mold construction layers. Without a powder bed needed, the mold defines the geometry, dimensions and surface finish of a three-dimensional object manufactured, so that in the processan energy source or combined sources can be selected from a large group for fusion, sintering, consolidating, joining, curing, or hardening in processing different forms and types of feedstock materials to manufacture metallic, polymeric or composite objects or parts.

Description

[0001] Cross-referenced related applications [0002] This patent application claims priority based on US 62 / 707022 preparatory patent application titled "Material Melting Method Three-dimensional Additive Manufacturing" filed on October 17, 2017 by Teng Yixian, which is incorporated herein by reference for all purposes. Technical field [0003] The present invention generally relates to a manufacturing method, more specifically but not limited to a method of building a three-dimensional object in a surrounding closed structure constructed layer by layer, the closed structure determining its geometric shape during the molding process of the three-dimensional object And size. This closed structure is essentially a forming mold constructed layer by layer corresponding to a set of cross-sectional geometric shapes, in which raw materials are added to build a three-dimensional object. Background technique [0004] In the past century, many manufacturing methods and equipment have been u...
