LLNL researchers have used multi-material 3D printing to create tailored gradient refractive index glass optics that could make for better military specialized eyewear and virtual reality goggles.Read more
Forget glue, screws, heat or other traditional bonding methods. A Cornell University-led collaboration has developed a 3D printing technique that creates cellular metallic materials by smashing together powder particles at supersonic speed.Read more
A team at Aalto University has used bacteria to produce intricately designed three-dimensional objects made of nanocellulose. With their technique, the researchers are able to guide the growth of bacterial colonies through the use of strongly water repellent – or superhydrophobic – surfaces.Read more
The American Society of Mechanical Engineers (ASME) has released a new white paper, “Medical Additive Manufacturing/3D Printing Year in ReviewRead more
Irvine, Calif., Oct. 21, 2020 – With one of the more awe-inspiring names in the animal kingdom, the diabolical ironclad beetle is one formidable insect. Birds, lizards and rodents frequently try to make a meal of it but seldom succeed. Run over it with a car, and the critter lives on. The beetle’s survival depends on two key factors: its ability to convincingly play dead and an exoskeleton that’s one of the toughest, most crush-resistant structures known to exist in the biological world.Read more
A Lawrence Livermore National Laboratory team, along with their collaborators, has become the first to produce a living, bioprinted aneurysm outside of the human body, perform a medical procedure on it, and observe it respond and heal as it would in an actual human brain.Read more
ORNL has 3D printed a channel bracket to go into reactors at Browns Ferry Nuclear Plant this spring, to demonstrate the viability of pre-qualified additively manufactured reactor components.Read more
In a groundbreaking new study, researchers at the University of Minnesota, in collaboration with the U.S. Army Combat Capabilities Development Command Soldier Center, have 3D printed unique fluid channels at the micron scale that could automate production of diagnostics, sensors and assays used for a variety of medical tests and other applications. The team is the first to 3D print these structures on a curved surface, providing the initial step for someday printing them directly on the skin for real-time sensing of bodily fluids.Read more

Oak Ridge National Laboratory and Department of Energy officials dedicated the launch of two clean energy research initiatives that focus on the recycling and recovery of advanced manufacturing materials and on connected and autonomous vehicle technologies.Read more
New Brunswick, N.J. (Sept. 16, 2020) – FDA guidelines for making 3D-printed masks, face shields and other personal protective equipmentRead more
Researchers from the University of Minnesota, with support from Medtronic, have developed a groundbreaking process for multi-material 3D printing of lifelike models of the heart’s aortic valve and the surrounding structures that mimic the exact look and feel of a real patient.
These patient-specific organ models, which include 3D-printed soft sensor arrays integrated into the structure, are fabricated using specialized inks and a customized 3D printing process. Such models can be used in preparation for minimally invasive procedures to improve outcomes in thousands of patients worldwide.
