Phase I IUCRC at University of Massachusetts Lowell: Center for Science of Heterogeneous Additive Printing of 3D Materials (SHAP3D)

IUCRC异质3D材料添加剂打印科学(SHAP3D)将服务于行业、政府和学术界的不同利益，以解决基础研究挑战，以满足行业对异质3D材料打印的商业需求。加法制造被汽车、医疗、航空航天、消费品等行业视为全球竞争优势的研究领域。SHAP3D旨在通过满足两个关键市场需求，加速国内AM行业及其客户的扩张和竞争力：(1)AM成长为更复杂的拓扑、异类和多功能应用，获得与其提高的性能相称的高利润率；(2)AM通过大幅提高吞吐量、降低每性能材料的成本以及使中小企业和大公司能够快速采用先进技术的易用性设计规则，向低利润率行业扩张。该中心将向行业成员和从业者以及更广泛的学术界传播其设计、材料和工艺研究。SHAP3D将通过产业界和学术界的密切合作，提供一支受过技术培训的、具有产业视角的劳动力队伍。与此I/UCRC相关的统一建模语言特定地点教育计划包括K-12模块、新生合作奖学金和在线教育计划。SHAP3D中心的研究将由工业的性能要求推动，建立在与体素级别控制和不同工艺和材料的集成相关的基本结构-加工-性能关系的技术基础上。这些多材料系统中可能存在的大量材料组合乘以具有体素级别状态变量控制的过程中表示的参数空间，需要对材料(组成基质、填料/添加剂、界面)的性质、加工规程和设计规则有基本的了解，以可靠地预测产品和部件的性能。尽管有不同的材料和工艺组合，但它们由许多与熔化、加工和固化以及材料异质添加剂印刷的界面物理相关的基本物理原理统一起来。该中心将支持成员选择AM方法和设想研究，包括多种添加印刷方法，如熔丝制造(FFF)、立体平版/数字光投影(SLA/DLP)和其他添加方法。马萨诸塞大学洛厄尔分校(UML)的网站将在建模、材料特性、加工、流变学、多材料印刷和添加剂制造的新材料方面增加研究实力。该中心和统一建模语言网站将通过实现他们的愿景，将不同的材料添加到不同的、增值的产品中，从而为工业增加显著的价值。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。

The IUCRC Science of Heterogeneous Additive Printing of 3D Materials (SHAP3D) will serve the diverse interests of industry, government, and academia to address fundamental research challenges to meet the commercial needs of industry for heterogeneous 3D printing of materials. The additive manufacturing (AM) is viewed as a research area for global competitive advantage by industries such as automotive, medical, aerospace, and consumer products. SHAP3D aims to accelerate expansion and competitiveness of the domestic AM industry and its customers by addressing two critical market needs: (1) the growth of AM into more complex topologies, heterogeneous, and multi-functional applications that command high margins commensurate with their increased performance, and (2) the expansion of AM into lower margin industries via order-of-magnitude improvements in throughput, material-per-performance cost reductions, and ease-of-use design rules that enable SMEs and large companies to rapidly adopt advanced techniques. The Center will disseminate its design, material and process research to industrial members and practitioners, and the broader academic community. SHAP3D will provide a technically trained workforce, with industrial perspective, through the close collaboration between industry and academia. UML site-specific educational programs associated with this I/UCRC include K-12 modular block, freshman Co-op Scholars and online education programs. The SHAP3D Center research will be driven by the performance requirements of industry, built from a technical foundation of the fundamental structure-processing-property relationships associated with the voxel-level control and integration of diverse processes and materials. The enormous number of material combinations possible in these multi-material systems multiplied by the parameter space represented within processes with voxel-level state-variable control requires fundamental understanding of the material (constituent matrices, fillers/additives, interfaces) properties, processing protocols, and design rules to reliably predict the properties of products and parts. Despite the diverse materials and process combinations, they are unified by many underlying physical principles related to melting, processing, and solidification, and interfacial physics for heterogeneous additive printing of materials.. The Center will support members' choice of AM methods and envisions research that encompasses numerous additive printing methods, such as fused filament fabrication (FFF), stereolithography/digital light projection (SLA/DLP), and other additive approaches. The University of Massachusetts, Lowell (UML) site will add research strength in modeling, material characterization, processing, rheology, multi-material printing, and new materials for additive manufacturing. The Center and UML site will add significant value for industry by addressing their vision to additively manufacture dissimilar materials into heterogeneous, valued-added products imbued with previously unattained biological, chemical, electrical, and mechanical functionality.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
