New Approach Enables Unprecedented Detail for 3D Microprinted Parts

HRL Laboratories, LLC’s additive manufacturing team has demonstrated 3D-printed polymer interposers with previously impossible slanted and curved vias with diameters of less than 10µm. Vias are small openings in the insulating layers of integrated circuits that allow conductive connections between semiconductor layers.


HRL Laboratories Research Scientist Selected for Frontiers of Engineering Symposium

HRL Laboratories, LLC, announced that Aruna Jammalamadaka, a research staff scientist in HRL’s Information and Systems Sciences Lab, was the latest HRL researcher to join other early-career engineers selected to take part in the National Academy of Engineering’s 26th Annual US Frontiers of Engineering Symposium, this year conducted virtually.



HRL’s Resin 3D Printed in Space

Pre-ceramic resin invented by HRL’s Additive Manufacturing group has been delivered to the International Space Station aboard the Cygnus unmanned resupply spacecraft. HRL’s material was then part of the first ever stereolithography 3D printing operations in space.


Human-Machine System to Enhance Software Analyst Performance

HRL Laboratories has begun development of a system that will assist program analysts as they search for vulnerabilities in compiled software. The Cognitive Aid for Vulnerability Analysis project has a multi-tiered approach to accelerate reverse-engineering and software comprehension by addressing the gap in human-machine systems that limits their recognition and adaptation to human thought processes, such as attention decay and fatigue, that reduce performance during detection of accidental or malicious vulnerabilities in compiled binaries.


HRL Laboratories Ramps Up High-Speed Gallium Nitride Semiconductor Foundry

HRL Laboratories, LLC, has scheduled quarterly multi-project wafer (MPW) runs in calendar years 2021 and 2022 for its T3 gallium nitride (GaN) monolithic microwave integrated circuit (MMIC) technology. HRL’s T3 GaN is a leading-edge millimeter-wave (mmW), high-electron-mobility transistor technology for next-generation, high-data-rate wireless communications, high-resolution radar imaging, and many other defense and civilian applications.


Complex Analytics of Network of Networks – CANON

A new software system developed by HRL Laboratories will enable open-source intelligence analysts to track down adversarial activity through complex networks of networks worldwide.


New Research Advances the Art of 3D-Printed Metal

HRL Laboratories, LLC, continues its research push to advance the state of the art in additive manufacturing (AM) of high performance alloys. The HRL AM team’s new paper elucidates the fundamental physics behind HRL’s expertise, which enables significantly improved control of how 3D-printed metals melt and solidify. The paper, Grain refinement mechanisms in additively manufactured nano-functionalized aluminum, was published online in September 2020 ahead of the November print issue of the journal Acta Materialia.


HRL Laboratories Sets Sights on Next-Generation Defense Electronics With Advanced Semiconductor Material

HRL Laboratories scientists are aiming for a disruptive improvement in radar, electronic warfare, and communications capabilities they hope will be enabled by their new project. If they are successful, the W-band, nitrogen-polar gallium nitride low-noise amplifier could be the world’s first such device, launching a new generation of defense-oriented electronics applications with a possible improvement of 4 times the output power in W bands over HRL’s existing technology.


HRL Advances to Next Phase in DARPA DREaM Project for Ultra-linear High-speed GaN Transistors

At HRL Laboratories, LLC, a team led by Principal Investigator Dr. Jeong-Sun Moon is developing the next generation of gallium nitride (GaN) transistors that will have a dramatic effect on electronic components that amplify electromagnetic signals for communications, radar, and 5G wireless networks. The MMIC amplifiers that utilize these high-speed GaN transistors can see greatly improved linearity, noise reduction, and reduced power consumption.
