3D PRINTING
A novel 3D-printing technique will enhance the production of biomedical parts
Researchers have created cellular metallic materials by smashing together powder particles at supersonic speed
3D printing has shown great promise when it comes to using tech for good. The futuristic technique has especially been extremely useful in Healthcare, with its various applications we have seen in the field over the course of the last 12 months — Living Skin, Mini-Livers, and biomimetic tongue to name a few. It has also made some significant breakthroughs like building the World’s first 3D Printed Neighborhood in Mexico, for people most in need.
Conventional 3D printing of metal objects & parts involves firing a laser at a bed of metal powder to selectively melt sections into the desired shape. The other and more commonly used one is called “cold spray” — which involves firing metal powder at high speeds at a substrate to fuse the particles together. This technique creates mechanically robust, porous structures that are 40% stronger than similar materials made with other conventional manufacturing processes.
Building and improving on the cold spray technique, researchers at Cornell University have developed a novel 3D printing technique…
