This Project Grant award from the National Science Foundation (NSF) Directorate for Engineering (CFDA 47.041) totaling $344,918 will establish a collaborative research program at Florida International University (FIU) to develop advanced data-driven approaches for additive manufacturing (AM) or 3D printing of materials with locally tunable electrical and mechanical properties. The research aims to create new polymer resin formulations for digital light processing (DLP) 3D printing that can...
This $404,595 National Science Foundation (NSF) Engineering program grant, awarded to the University of Delaware on March 1, 2024, supports research to enhance multi-material additive manufacturing (3D printing) through the use of advective assembly techniques. The project aims to develop modular 3D printing nozzles capable of rapidly structuring and depositing multi-material composites at higher resolution and volumetric throughput than conventional methods. This could enable new applications...
This Project Grant award, provided by the National Science Foundation's Engineering program (CFDA 47.041), supports research into a mold-free, fast, and cost-effective manufacturing process for commonly used polymer parts. The $550,000 award, effective May 1, 2025 through April 30, 2028, will fund a study of a self-propagating polymerization front technique inspired by natural growth processes. This additive manufacturing method aims to eliminate the need for expensive molds, reduce production...
This National Science Foundation (NSF) Faculty Early Career Development (CAREER) Project Grant, awarded under the NSF Engineering program (CFDA 47.041), will support fundamental research to enable additive manufacturing of high-performance polymer composites containing a high concentration of carbon fibers. The $647,188 award to Arizona State University will develop a new composite manufacturing platform that uses remote heating to instantaneously polymerize and rigidize the printed composite...
This $578,437 National Science Foundation project grant supports research at Texas A&M University to develop fast manufacturing techniques for high-performance thermoplastic polymer composites. The research aims to engineer the crystallinity of these composites during fast processing to achieve high stiffness, strength and toughness concurrently. Nanomaterials consisting of cellulose nanocrystals and graphene nanoplatelets will be used to control crystallinity without hazardous solvents...
This $299,431 National Science Foundation (NSF) Integrative Activities (CFDA 47.083) project grant will support an assistant professor at the University of Alabama in Huntsville (UAH) to develop experimental and computational modeling techniques for accurately predicting the dynamic fracture and deformation behavior of polymer matrix composite (PMC) materials. The project aims to enable the widespread adoption of PMCs in critical aerospace, automotive, and maritime applications by improving...
This $511,664 federal Project Grant award, provided by the National Science Foundation's (NSF) Engineering program (CFDA 47.041), aims to fundamentally transform the vat photopolymerization (VP) additive manufacturing process. The goal is to develop an "ICLIP" process that injects resin through the printed part to significantly increase printing speed and enable high-resolution, multi-material 3D printing. The research will involve computer simulations to optimize the resin injection...
This $250,000 Project Grant award from the National Science Foundation's (NSF) Engineering program (CFDA 47.041) supports a collaborative research project led by the University of Pittsburgh. The objective is to develop an approach for optimally determining laser scan sequences in laser powder bed fusion (LPBF) additive manufacturing processes. The research aims to uncover the relationships between optimal scan sequences, temperature distribution, distortion, and residual stress in LPBF. This...
