3D Printed Zoetrope Creates Moving Figures Made of Light

A 3D-printed piece by media artist Akinori Goto operates like a zoetrope (pre-film animation devices that produce the illusion of motion by displaying a sequence of drawings or photographs) with the combination of movement and light creating impressions of walking and dancing people // Read More // Watch Video

3D Printed Flexible Cubes—Programmed Deformation from Pressure

A group of researchers  have developed 3D printed metamaterial blocks that hide programmable geometric patterns to perform a certain function when exposed to pressure. This material breakthrough was realized by researchers Corentin Coulais, Eial Teomy, Koen de Reus, Yair Shokef and AMOLF group leader professor Martin van Hecke, who claim that the same design principles can be applied to larger objects to create predictable and functional deformations // Read More // Watch Video

LLNL Researchers' New Metal 3D Printing Techniques Could Revolutionize Laser Design

Researchers at Lawrence Livermore National Laboratory are using metal 3D printing to create strong and lightweight structures for advanced laser systems. Using a powder bed SLM 3D printer, a team of LLNL researchers led by physicist Ibo Matthews is experimenting with printing techniques in order to create new laser system components. “With precision, predictive control of 3D printing you can put the stiffness where you need can create functionally graded structures for optical lasers and mounts that are impossible to make by conventional manufacturing methods” // Read More

Johns Hopkins Researchers Develop 3D Printable Bones Using Real Bone Cells

An associate professor of biomedical engineering at Johns Hopkins University School of Medicine, Warren Grayson, Ph.D., has developed a groundbreaking recipe for natural, 3D printable bone scaffolds. They are made with a combination of man-made, biodegradable plastics and pulverized natural bone material. Using this mix of ingredients, doctors could potentially 3D print replacement bones that could be implanted in the patient’s body // Read More
