Seed Grants 

The Consortium for Innovation in Manufacturing and Materials (CIMM) solicits proposals for CIMM Seed Funding each year to support research projects relevant to CIMM’s advanced manufacturing themes. The current Science and Technology Thrusts (STTs) of CIMM address underlying technologies in two areas: 1) STT1 (Multiscale metal forming and replication) addresses challenges in high-throughput manufacturing of components with functional features ranging from microns to millimeters and beyond with high fidelity and repeatability; 2) STT2 (Laser-based 3D metal printing) focuses on adaptive manufacturing of application-specific structures with a high degree of geometric and microstructural complexity and variability. The unifying scientific challenge for these STTs is the multiscale nature of the underlying phenomena, which span multiple length scales (nanometers to millimeters and beyond) and time scales (nanoseconds to hours).  A major challenge in multiscale forming is that well-established macroscale manufacturing methods cannot be simply scaled down to the relevant dimensions. To address this, STT1 tightly couples experimentation with modelling and simulation on multiscale plasticity and physics and mechanics of interfacial regions, with focus on mechanical size effects and engineered interfaces. A major challenge in laser-based 3D metal printing is that an understanding of the complex interplay between multi-physics and multiscale phenomena—which are required for tailoring composition and microstructure of printed parts—is presently incomplete. To address this, STT2 couples experimentation with hierarchical modeling and simulation tools, with a focus on laser printing processes and custom powder synthesis. Experimentally validated models and simulation tools, developed through this effort, will lead to advancement of scientific understanding and acceleration of further technology development. CIMM’s research program also includes the development of data handling and workflow management capabilities to support material and process development within the Integrated Computational Materials Engineering (ICME) framework. CIMM is developing multiple facilities in the State to support advanced manufacturing research and development, and also coordinating a network of user facilities on multiple campuses where CIMM-affiliated users are given access at the same rates charged to the on-campus users. Collectively, these are called CIMM Core User Facilities (CIMM-CUFs).
