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

IUCRC的3D材料异质增材打印科学（SHAP 3D）将服务于工业、政府和学术界的不同利益，以解决基础研究挑战，满足工业对材料异质3D打印的商业需求。增材制造（AM）被汽车、医疗、航空航天和消费品等行业视为全球竞争优势的研究领域。SHAP 3D旨在通过解决两个关键的市场需求来加速国内AM行业及其客户的扩张和竞争力：（1）AM向更复杂的拓扑、异构和多功能应用的增长，这些应用要求与其增加的性能相称的高利润，以及（2）通过吞吐量的数量级改进，AM向低利润行业的扩展，材料性能成本降低，以及易于使用的设计规则，使中小企业和大公司能够迅速采用先进的技术。该中心将向工业成员和从业人员以及更广泛的学术界传播其设计，材料和工艺研究。SHAP 3D将通过工业界和学术界之间的密切合作，提供一个受过技术培训的劳动力，具有工业视角。与此I/UCRC相关的UML站点特定教育计划包括K-12模块化块，新生合作学者和在线教育计划。SHAP 3D中心的研究将由行业的性能要求驱动，建立在与不同工艺和材料的体素级控制和集成相关的基本结构-加工-性能关系的技术基础上。在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）特性，加工协议和设计规则有基本的了解，以可靠地预测产品和部件的特性。尽管材料和工艺组合多种多样，但它们通过与熔化、加工和固化相关的许多基本物理原理以及用于材料的异质增材打印的界面物理学而统一起来。该中心将支持会员选择增材制造方法，并设想研究包括许多增材打印方法，如熔丝制造（FFF），立体光刻/数字光投影（SLA/DLP）和其他增材方法。马萨诸塞州洛厄尔大学（UML）的网站将增加建模，材料表征，加工，流变学，多材料打印和增材制造新材料的研究力量。 该中心和UML网站将通过实现他们的愿景，将不同的材料增材制造成具有以前无法实现的生物，化学，电气和机械功能的异质，增值产品，为行业增加重要价值。该奖项反映了NSF的法定使命，并被认为值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估来支持。

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.
