Additive Manufacturing Material Properties Generation for Critical Applications: New Approaches, Challenges, Opportunities

增材制造为制造业带来了巨大的机遇，在新的结构设计，更高的性能，以及减少重量和所需材料方面。然而，为了释放这一潜力，行业需要创建高质量的数据集来实现设计和产品认证。ASTM国际在通过ASTM AM卓越中心（AM CoE）推动材料性能生成方面处于领先地位，该博士学位支持为关键应用创建材料性能。这将包括理解和评估缺陷的影响，测试方法，以及将制造增材制造材料的过程与服役部件的寿命联系起来。该项目将主要以斯旺西大学为基地，但设想在附属大学和合作伙伴之间进行联络和研究活动。该博士学位的成果将支持增材制造标准化，通过广泛的ASTM国际网络为学生提供全球曝光。将提供专业的增材制造培训，以及作为AM CoE成员与国际合作伙伴合作的机会。ASTM国际增材制造CoE于2018年专门创建，旨在通过快速缩小标准差距并提供教育和劳动力发展来加速增材制造，并得到全球创始（例如MTC， NASA）和战略合作伙伴的支持。ASTM领导了AM内部的许多重要合作，特别是ISO和ASTM之间的标准开发合作伙伴SDO。增材制造CoE汇集了行业、政府和学术界，以优化增材制造研发和标准开发流程。通过紧密耦合这些过程，标准可以更快地进入需要它们的人手中，大大缩短AM上市时间并增加广泛采用。经验涵盖所有增材制造方法，具有各种增材制造模式的优势，包括粉末床，粘合剂喷射和直接能量沉积。

Additive Manufacturing brings significant opportunities for Manufacturing, in terms of new structural designs, higher performance, and a reduction in weight & material required. However, for this potential to be unlocked, industry requires the creation of high calibre datasets to enable design & product certification.ASTM International is at the forefront of driving material property generation with the ASTM AM Centre of Excellence (AM CoE), with this PhD supporting the creation of materials properties for critical applications. This will include understanding & evaluating the effect of defects, test methods, and relating the process of creating AM material to the lifing of a component in service. The project will be predominantly based at Swansea University, but liaison and research activities at affiliated universities and partners is envisaged.The output of this PhD will support Standardisation for Additive Manufacturing, providing the student with global exposure through the extensive ASTM International network. Specialist Additive Manufacturing training will be provided, as well as the opportunity to collaborate with international partners whilst working as a member of the AM CoE.The ASTM International AM CoE was specifically created in 2018 to accelerate Additive Manufacturing through rapidly closing gaps in Standards and providing Education & Workforce Development, with support from global founding (e.g. The MTC, NASA) and strategic partners. The ASTM has led many significant collaborations within AM, notably the Partner SDO between ISO and ASTM for Standards development.The AM CoE brings together industry, government, and academia to optimise the AM R&D and standards development processes. By tightly coupling these processes, standards get into the hands of those who need them faster, drastically reducing AM time to market and increasing widespread adoption. Experience covers all AM methods, with strengths in various AM modalities including Powder Bed, Binder Jetting and Direct Energy Deposition.
