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%.

New Manuscript Published – Adhesion of Reactive Silver Ink on Indium Tin Oxide

Our article on the Adhesion of Reactive Inks on Indium Tin Oxide was just published in the Journal of Material Science.  Good work Avinash and April!

Introducing Dr. Lefky

Congratulations to Chris on passing his Ph.D. Defense on the Corrosion and Sensitized Microstructure Evolution of 3D Printed Stainless Steel 316 and Inconel 718 Dissolvable Supports.  Chris has worked extremely hard over the last 4 years, publishing 12 manuscripts (7 first author) in topics ranging from reactive inks, to electrohydrodynamics, to the sensitization and corrosion of 3D printed metals.

We are all extremely proud of Dr. Lefky and wish him the best of luck as he starts his new job at Arconic.

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.
