Embodiment Construction

[0066] The detailed description, set forth below in connection with the accompanying drawings, is intended to be a description of various configurations and is not intended to represent the only configurations in which the concepts described herein may be implemented. The detailed description contains specific details for the purpose of providing a thorough understanding of various concepts. It will be apparent, however, to one skilled in the art that these concepts may be practiced without these specific details.

[0067] figure 2 with image 3 An example support structure 210 that can be constructed alongside object 200 is illustrated. figure 2 Pictorial perspective, and image 3 Illustrated floor plan. Support structure 210 and object 200 may be manufactured according to an AM process. For example, use figure 1 The device 100 and the method described above. In this type of AM process, object 200 is built layer by layer by selectively sintering or melting powder reg...

Abstract

The present disclosure generally relates to methods for additive manufacturing (AM) that utilize support leading edge structures in the process of building objects, as well as novel leading edge support structures to be used within these AM processes. The support structure is positioned adjacent the object between the object and a first side of the powder bed. The support structure has a shape that tapers outward in the direction from the first side to the object.

Description

technical field [0001] The present disclosure generally relates to methods for additive manufacturing (AM) utilizing support structures in the process of building objects, and novel support structures to be used within these AM processes. Background technique [0002] In contrast to subtractive manufacturing methods, the AM process typically involves the accumulation of one or more materials that are used to make a net-shape or near-net-shape (NMS) object. While "additive manufacturing" is an industry standard term (ASTMF2792), AM encompasses a variety of manufacturing and prototyping techniques known under a variety of names, including freeform fabrication, 3D printing, rapid prototyping / tooling, and more. AM technology enables the fabrication of composite components from a wide variety of materials. Typically, individual objects can be fabricated from a computer-aided design (CAD) model. One particular type of AM process uses energy beams, such as electron beams, or elec...
