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.

SRAS（空间分辨声学光谱）是一种无损评估方法，允许工程师通过评估 SAW（表面声波）来了解晶体和多晶材料的晶体取向。目前，SRAS 用于研究材料后制造中的微观结构。该研究项目旨在进一步开发 SRAS 技术，以便能够在整个增材制造生产过程（称为 L-PBF（激光粉末床熔融））的制造过程中对材料进行主动研究。这将能够在制造过程中通过非破坏性手段主动评估组件的晶体结构。通过将这些信息反馈到 3D 打印系统中，该项目希望开发生产具有特定晶体结构的 3D 打印合金的能力。
