Northeastern researchers develop new way to 3D print طريقة شراء اسهم دو perusahaan forex di surabaya By Elise Harmon, news editor

الاستشارات للاسهم السعودية A group of three Northeastern University researchers – agraduate student, undergraduate and professor – are changing the way material scientists and engineers can 3D print small devices.

valutahandel beskattning Joshua Martin, Brad Fiore and Randall Erb published their paper “Designing bioinspired composite reinforcement architectures via 3D magnetic printing” in the science journal Nature Communications on Oct. 23. The paper documented their development of a way to 3D print composite materials on a micro scale. forex buy sell signals and alerts “We are mixing ceramics with polymers,” Erb, a professor of mechanical and industrial engineering at Northeastern, said. “You get the best of both worlds.You get the strength and stiffness of ceramics with the flexibility of polymers… There was no good way to 3D print composites until we came along. We invented this new method to print composites تداول اسهم ام القرى الثلاثاء ١ ١٠ , and the key is that you have to control the orientation of very small fibers within your polymer matrix.” استثمار الذهب في دبي The researchers, who are all part of the Directed Assembly of Particles and Suspension (DAPS) lab at Northeastern, are the first to apply magnetic fields to orient ceramic particles inside 3D-printed devices, according to Erb. Without orienting the particles, the composite is weaker than a pure polymer, but if they are oriented, the product is stronger.

Industrial applications include printing custom-reinforced prostheses and orthotics or complex parts for aerospace applications.

متى تداول اسهم الحكير للسياحه “Throughout the process, I was just trying to think ‘How can we make this good?,’ ‘How can we get the results we’re looking for?’ ‘How can we make this work?’” he said. “Now I’m just really excited to be a part of it. It’s so applicable in so many different field that it would be really great to see it really grow and expand.” موقع تداول الأسهم السعودية Photo courtesy MKzero, Flickr
