Critical Contributions to Critical Challenges • April 09, 2024

Hunter Turco, a senior mechanical fabrication technician, adjusts parts on a 3D printer in one of APL’s fabrication facilities. APL installed an identical machine on board the USS Bataan (LHD 5) last October and helped sailors print replacement parts for the ship while at sea.

Johns Hopkins APL and Navy Chart Next Steps to Accelerate 3D-Printing Advancements

To address manufacturing challenges, the Navy is prioritizing the development and fielding of additive manufacturing systems, often called 3D printers, to supplement traditional casting methods and accelerate submarine production. APL is leading the charge in the development of tools and strategies that will speed up and improve inspection of additively manufactured parts.

Our food supply faces several emerging threats, but APL is helping the federal government prepare to restructure to be better positioned to defend the nation’s food, agriculture and veterinary systems.

Protecting America’s Food and Agriculture From Emerging Threats

America’s food supply faces a number of emerging threats, including the effects of climate change, cyberattacks and even espionage. As the U.S. government enhances defense of agricultural systems, researchers at APL are poised to assist.

APL Team Readies Advanced Imager for Integration Onto NASA’s Interstellar Mapping and Acceleration Probe

Another instrument planned for flight aboard NASA’s Interstellar Mapping and Acceleration Probe (IMAP) is ready for installation on the spacecraft. IMAP-Ultra, a particle imager capable of capturing energetic neutral atoms, particularly hydrogen atoms, made the short trip between clean rooms on APL’s campus as part of IMAP’s integration and testing campaign.

A mounted plastic prototype of the Compact Hyperspectral Air Pollution Sensor Demonstrator (CHAPS-D) instrument, additively manufactured at APL. The prototype shows regions that will be additively manufactured aluminum (white), traditionally machined parts (red) and the instrument detector’s location (yellow).

Lab Researchers Take Additive Manufacturing to New Heights

Engineers and researchers at APL recently won two awards from The Minerals, Metals & Materials Society for their study on 3D-printing a space instrument to detect and source air pollution. The project marks a significant milestone in the 3D-printing industry because it relies on an end product to help build a framework for material selection, characterization and development.

3rd National Workshop on Marine eDNA

June 3-5 • Johns Hopkins APL, Laurel, MD, and Smithsonian National Museum of Natural History, Washington, D.C.

The biennial National Workshop on Marine Environmental DNA (eDNA) serves as a mechanism to bring together researchers, practitioners and policymakers to discuss eDNA technologies, newly released national strategies and implementation priorities. The three-day workshop will include speaker presentations and panel discussions as well as poster/demo and networking sessions. Shuttles will be provided to transport guests from Laurel, Maryland, to Washington, D.C., for the last day of the event. Registration is open.

APL Honored Twice on Fast Company’s 2024 ‘Most Innovative Companies’ List

Two breakthrough technologies from APL received Most Innovative Companies awards from Fast Company. APL was ranked No. 6 in the Rapid Response category for biothreat characterization technology and No. 10 in the Applied Artificial Intelligence (AI) category for its use of AI to identify climate tipping points.
