Problems solved by technology
Grinding rough surfaces and other finishing tasks to improve the surface quality of parts can be expensive, difficult, time-consuming and / or labor-intensive, reducing manufacturing efficiency and increasing production costs
Additionally, for parts with inaccessible regions, typical post-processing may not be effective or possible, and current methods may be insufficient
Furthermore, if the surface quality, subsurface quality, or dimensional accuracy of the build part is sufficiently degraded during the additive manufacturing process, the entire build part may need to be scrapped, which is a waste of time and resources

Embodiment Construction
[0022] The foregoing summary and the following detailed description will be better understood as described above in conjunction with the drawings. As used herein, and recited in the singular form of the word "a" or "an" preceding an element or step does not have to be understood as excluding plural elements or steps. In addition, reference to "one embodiment" are not intended to be interpreted as excluding the existence of additional features including the embodiment. Further, unless expressly stated to the contrary, embodiments "comprising" or "having" an embodiment one or more elements having a particular property may include other elements not having that property.
[0023] Considering the cost of performing the surface treatment after the additive manufacturing process, the time and labor, additive manufacturing techniques build member has many advantages, these techniques inherently improved surface quality, near-surface quality and geometric accuracy, thereby eliminating or ...

Abstract
The application relates to an additive manufacturing system and method. The additive manufacturing system includes one or more processors configured to determine one or more geometrical characteristics of each of multiple segments of a build part at a candidate position relative to an additive manufacturing instrument. The one or more geometrical characteristics include an angle of incidence between a beam line extending from a beam source and a surface normal of a respective skin of the corresponding segment proximate to the beam line. The one or more processors are configured to control the additive manufacturing instrument, based on the one or more geometrical characteristics, to direct focused energy beams from a first orientation relative to the build part to form a first segment of the segments of the build part and to direct focused energy beams from a second orientation relative to the build part to form a second segment of the segments of the build part.
Description
Technical field [0001] Construction relates to additive manufacturing three-dimensional parts of the embodiments of the present disclosure generally embodiment. Background technique [0002] It refers to additive manufacturing process for producing a three-dimensional construct of any member, wherein depositing a continuous layer of base material under computer control. Selectively depositing a layer fused by a focused energy beam (e.g., laser) (which was heated and adhesive material) is applied. Construction member may be based on the size and shape of a three-dimensional computer model or another electronic data sources. Additive manufacturing can be used to manufacture an object having a complex structure and shape. Compared with the conventional metal fabrication techniques (e.g., die casting, pressing or the like), additive manufacturing technique for manufacturing a metal member may be constructed to allow greater design freedom and produces a more accurate and repeatable f...
