Engineers reinvent ceramics with origami-inspired 3D printing
In a breakthrough that blends ancient design with modern materials science, researchers at the University of Houston have developed a new class of ceramic structures that can bend under pressure without breaking. Potential applications for the new technology range from medical prosthetics to impact-resistant components in aerospace and robotics, where lightweight but tough … [Read more...] about Engineers reinvent ceramics with origami-inspired 3D printing
Researchers develop new design and fabrication method to make lightsails for interstellar travel
In a potential step towards sending small spacecraft to visit other stars, researchers at Brown University in Providence, Rhode Island, and Delft University of Technology (TU Delft) in the Netherlands have developed an ultra-thin, ultra-reflective membrane designed to ride a column of laser light to incredible speeds. Since its launch in 1977, NASA’s Voyager 1 spacecraft has … [Read more...] about Researchers develop new design and fabrication method to make lightsails for interstellar travel
MIT engineers develop a fully 3D-printed electrospray engine
A team of MIT engineers has developed a fully 3D-printed electrospray engine, a device that applies an electric field to a conductive liquid, generating a high-speed jet of tiny droplets that can propel a spacecraft. These miniature engines are ideal for small satellites known as CubeSats, which are often used in academic research. Since electrospray engines utilise … [Read more...] about MIT engineers develop a fully 3D-printed electrospray engine
Sea sponge inspires super strong compressible material
Inspired by a deep-sea sponge, engineers at RMIT University in Melbourne have developed a new material with remarkable compressive strength and stiffness that could improve architectural and product designs. The double lattice design was inspired by the intricate skeleton of a deep-sea sponge, known as Venus’ flower basket, that lives in the Pacific Ocean. Post-doctoral … [Read more...] about Sea sponge inspires super strong compressible material
