The research objective of the award is to apply the principles of cold sintering for the freeform fabrication of diamond microtools and determine quantitative relationships among aspect ratio, surface roughness, edge radius and sintering parameters. The approach consists of employing laser-induced shock waves to mechanically sinter nanodiamond powders through layer-by-layer additive manufacturing and utilizing multiscale physics models to validate the experimental data. Three-dimensional microparts in various freeform geometries will be fabricated with a post-finishing treatment by the femtosecond pulsed laser for close tolerance, smooth finish and precise geometry. The broader impacts include a reduction in the manufacturing cost, easy availability and enhanced performance of diamond microtools. An additional benefit is the capability to build multifunctional materials for tailoring the required properties. Research will facilitate the industry adoption of the new manufacturing process to address the productivity and quality issues associated with diamond microtools. Education and outreach outcomes include training of women and minority graduate students in advanced manufacturing field, incorporation of the research data into manufacturing courses, undergraduates research training by involving them in the research team, dissemination of the research results through journal publications, conferences, industry visits and workshops, and creation of a website to report results of the new additive manufacturing system.

该奖项的研究目的是将冷烧结原理应用于钻石微工具的自由形式制造，并确定纵横比，表面粗糙度，边缘半径和烧结参数之间的定量关系。该方法包括采用激光诱导的冲击波通过逐层增材制造和利用多尺度物理模型来验证实验数据。各种自由形式几何形状中的三维微型明ar将通过飞秒脉冲激光器进行后处理后的处理，以近距离耐受性，光滑的效果和精确的几何形状。 更广泛的影响包括降低制造成本，易于可用性和钻石微工具的性能增强。另一个好处是能够构建多功能材料来定制所需属性。研究将促进行业采用新的制造过程，以解决与钻石微工具相关的生产力和质量问题。教育和外展成果包括对高级制造领域的妇女和少数群体研究生的培训，将研究数据纳入制造课程，本科生通过参与研究团队的研究培训，通过期刊出版物，会议，行业访问和研讨会来传播研究结果，以及创建新添加剂制造系统的网站。
