HRL Laboratories, LLC, is advancing its cutting-edge 3D-printed metals technology, extending an ever-widening portfolio of innovation in additive manufacturing with its 19th patent stemming from the revolutionary technology. HRL’s patent portfolio in this area extends back to 2014 with the early development of the process that would come to be known as functionalization.
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.
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.
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, LLC, reports a novel method used to additively manufacture—3D-print—components made from fracture-resistant ceramic matrix composites (CMCs). Published May 28, 2020 in The Journal of the American Ceramic Society, this technique makes possible a new range of complex designs with these durable materials.
HRL Laboratories has won an R&D 100 award in the Mechanical/Materials category for its 7A77 aluminum alloy powder project Nano-functionalized Alloys for Additive Manufacturing. High-strength aluminum alloy can be printed from the powder using standard additive manufacturing equipment, the first time this alloy has been 3D printable.
HRL Additive, a new commercial effort by HRL Laboratories, LLC, has secured the first commercial sale of its groundbreaking 7A77 high-strength aluminum 3D-printing powder to NASA’s Marshall Space Flight Center. The production plant is dedicated to producing the printable aluminum powder, designated as 7A77, the first additive feedstock registered by the Aluminum Association.
HRL Laboratories is commercializing its additively manufactured (3D-printed) high-strength aluminum, which has obtained the first ever registration of an additive alloy from the Aluminum Association. HRL will be granted registration number 7A77.50 for the aluminum powder used to additively manufacture the alloy, and number 7A77.60L for the printed alloy.
Setting another new milestone in metallurgy, scientists from HRL Laboratories have used their breakthrough process to 3D print metal matrix composite (MMC) parts utilizing a new nanofunctionalization process.
HRL Laboratories, LLC, has been won the silver medal in the Applied Technology/3D Printing category of the 2018 Edison Awards for their work in microstructure control of 3D printed materials.
