New Technologies Provide Opportunities for Remanufacturing

Technologies like 3D printing and automation prolong the life of products that consumers would typically throw out. When they need specific parts to repair their products—from power tools and coffeemakers to vacuums and smoke-detectors—they now reach out to companies, who can (courtesy of those tech improvements) remanufacture specific components. “Remanufacturing is a smart way to continue to advance without creating a lot of waste. The …

The Continued Quest for Pain-Free Microneedles

Produced through a process of 3D printing with polymers—altogether referred to as “4D printing” because of its core of programmable, shape-shifting material—rapidly developing microneedles may replace painful hypodermic needles in the next decade. Professor Howon Lee, who has lead the research from Rutgers University, has filed a patent on this new technology, which produces hollow needles that are barbed, much like the stinger of a …

MIT Scientists’ “4D Materials” Shape-Shift into Human Face

Nicknamed “active origami,” and referred to as a shape-morphing system, an MIT-developed “4D material” begins flat but can blossom into something more complicated when its surrounding conditions change. Specifically, its 3D-printed lattice structure, which mimics mesh, expands through temperature variation and actually turns into the face of scientist Carl Friedrich Gauss. The visual was reverse engineered and Gauss was selected as the sculptural result to …
