$1.6M NSF Grant awarded to Johns Hopkins and Georgetown University on Additive Manufacturing

Posted in PDO News

Professor Peter Olmsted has been awarded a grant from the NSF DMREF program, in collaboration with Johns Hopkins departments of Physics and Mechanical Engineering  (Professors Vicky Nguyen, Mark Robbins, Kevin Hemker, and Sung Hoon Kahn), to study additive manufacturing (3D printing). The grant is for $1.6M in total, with $230k allocated to Georgetown University, and will run from 2016-2020. We will also work closely with NIST during the project. 

This Designing Materials to Revolutionize and Engineer Our Future (DMREF) grant will provide new scientific understanding of the Fused Filament Fabrication (FFF) process and its effect on the underlying molecular structure and properties of 3D-printed polymers. 3D-printing is driving a paradigm shift in the design and manufacturing of objects both in every day life and in high-tech applications. The integration with computer-aided design allows printed parts to be customized quickly and inexpensively to meet unique specifications and provide new functionalities. FFF is the most widely used and fastest growing 3D process and FFF printers dominate the growing desktop 3D printing market, driven by the low cost and relative simplicity of the printer construction and wide availability of feedstock materials. Although widely used, applications of FFF printed materials are limited by modest strength and toughness and large variability in material properties. This award supports fundamental research to understand how the printing conditions affect the materials properties of polymers printed by FFF. This fundamental knowledge is needed to advance the application of FFF to structure-critical components, provide computational tools to accelerate the design of FFF printed parts, and develop the next generation 3D-printing technology for polymers. Thus, the outcomes of this project will benefit the US economy. This project will also provide opportunities for undergraduate and graduate students to participate in multidisciplinary research that involves close interactions with national laboratories and product design researchers, and create innovative outreach actives for K-12 on the science and engineering of 3D-printing.
