Embodiment Construction

[0018] Embodiments of the present application are directed to systems and methods that address various problems in the art that have been identified by the inventors. The inventors have recognized that improved techniques for generating auxiliary structures are needed to address various problems often encountered in 3D printing of objects. For example, auxiliary structures are often required to support areas of the model that are not self-supporting. These non-self-supporting regions tend to fracture and / or deform during this 3D printing process.

[0019] Auxiliary structures are also needed to compensate for other types of forces acting on the model that cause it to break and / or deform during the 3D printing process. In particular, the inventors have observed that certain areas in the part may deform during the 3D printing process. These deformations may be caused by thermal stress and / or shrinkage (especially in laser melting applications). And what's more, during 3D prin...

Abstract

Systems and methods for generating auxiliary structure points to 3D print models are disclosed. The auxiliary structure points may be used to add auxiliary structures to 3D models which compensate forforces acting upon or within the model during the 3D printing process to ensure a successful build process.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of and priority to: (1) U.S. Provisional Application No. 62 / 211,868, filed August 30, 2015; and (2) U.S. Provisional Application No. , filed August 31, 2016. 62 / 211,876. Each of the above-cited applications is hereby incorporated by reference in its entirety. technical field [0003] This application concerns support generation in additive manufacturing. More particularly, the present application relates to systems and methods for generating auxiliary structure points for adding auxiliary structure to a 3D model in order to compensate for forces acting on or within the model during the 3D printing process. Background technique [0004] In additive manufacturing (commonly known as 3D printing), objects are printed as a series of layers. These objects are typically created as 3D computer models that are provided to a 3D printing system for printing. In certain types of 3D printing...
