Methods and systems comprise new design procedures that can be implemented for additive manufacturing technologies that involve evaluation of stress concentration sites using finite element analysis and implementation of scanning strategies during fabrication that improve performance by spatially adjusting thermal energy at potential failure sites or high stress regions of a part.

Method and system for producing functionally graded structures in powder bed fusion processing

Methods and systems for manufacturing a three-dimensional product. Fabrication of a three-dimensional part from a powder spread over a work table as a powder bed can be initiated. The fabrication process can be paused to cool down the work table to room temperature to obtain access to the three-dimensional part for post-processing operations such as, for example, embedding external artifacts. Fabrication can continue by preheating the powder rather than the work table until fabrication of the three-dimensional part is complete. A damaged part may be placed within the powder bed, wherein the fabrication process can be directly initiated to achieve part repair. Additionally, a material of the same part's composition can be used or a different material utilized to render the part better than new. Access to the three-dimensional part allows embedding of a foreign object in the three-dimensional part within the powder bed while the three-dimensional part remains non-finished.
