SEMTE | Hildreth Lab

The Hildreth Research Group focuses on phenomena involved in nanometer to centimeter scale additive manufacturing technologies.  Through fundamental studies on mass transport, heat transfer, chemical kinetics, electrohydrodynamics, and corrosion, we are advancing the state-of-the-art for printed electronics and microfluidics; bringing dissolvable supports to 3D printed metals; and are reducing silver consumption in photovoltaic cells by 90%.

DOE NEUP grant for dissolvable supports for heat exchangers just funded!

Our DOE proposal on combining our Dissolvable Support Technology with University of Pittsburg’s Prof. Albert To’s Topology Optimization just got funded.  Congratulations to the PI, Prof. To along with the rest of the Co-PI’s: myself; Dr. Wei Xiong (University of Pittsburgh); Mr. Curt Horomanski (Curtiss-Wright EMD); Ms. Robin Gourley (Curtiss-Wright EMD); Dr. Jason Goldsmith (Kennametal).

This project aims to develop and establish an innovative approach to drastically reduce development and post-processing costs associated with laser powder bed additive manufacturing (AM) of complex nuclear reactor components with internal cavities and overhangs. The proposed innovative approach integrates dissolvable supports, topology optimization, and microstructure design to achieve the project goal. Using optimally designed dissolvable supports, this research will make state-of-the-art nuclear components much cheaper, have minimal distortion, and could eliminate build failures altogether.

NASA just funded our Dissolvable Support Proposal

Our NASA-CAN proposal just got accepted.  We look forward to working with Dr. Omar Mireles at NASA’s Marshall Space Flight Center as we develop this technology to aid NASA in their mission to explore the boundaries of space!  Just a few more years and we’ll have the replicator up and running.
