SRAS (Spatially resolved acoustic spectroscopy) is a non destructive evaluation method that allows engineers to access the crystallographic orientation of crystalline and polycrystalline materials through the assessment of SAW (surface acoustic waves). Currently SRAS is used for the study of microstructures in materials post fabrication. The research project aims to further develop the SRAS technique to enable the active study of materials during fabrication throughout the additive manufacturing production process known as L-PBF(laser powder bed fusion). This will enable the active assessment of the crystallographic structure of components during fabrication through non destructive means. By feeding this information back into 3D printing systems, the project hopes to develop the capabilities in producing 3D printed alloys with specific crystallographic structures.

SRA（空间分辨的声学光谱法）是一种非破坏性评估方法，它使工程师可以通过评估锯（表面声波）来访问晶体和多晶材料的晶体学方向。目前，SRA用于研究制造后材料中的微观结构。该研究项目旨在进一步开发SRAS技术，以在整个添加剂制造生产过程中（Laser Powder Bed Fusion）在制造过程中进行积极研究。这将使通过非破坏性手段在制造过程中对组件的晶体结构进行积极评估。通过将这些信息馈回3D打印系统，该项目希望开发具有具有特定晶体学结构的3D打印合金的能力。
