Researchers at RMIT have found that sound vibrations can improve the micro-structure of 3D printed alloys.The team used high frequency sound waves to make the alloys more consistent and stronger than those printed conventionally. Lead author, Carmelo Todaro, highlighted that the method deals with inconsistencies in 3D printed alloys.“If you look at the microscopic structure of 3D printed alloys, they’re often made up of large and elongated crystals,” Todaro explained.“This can make them less acceptable for engineering applications due to their lower mechanical performance and increased tendency to crack during printing.”After the sound vibrations were applied during the printing process, testing showed a 12 per cent improvement in tensile strength and yield stress.“The microscopic structur...

The U.S. Army has demonstrated its interest in additive manufacturing over the years, but according to service secretary Ryan McCarthy, it’s now time to really ramp up adoption. At a recent press event at the Reagan National Defense Forum, McCarthy emphasized how crucial 3D printing will become to the military, especially for the production of spare parts.Presently, the U.S. military is using additive manufacturing, though in a limited capacity. For the production of spare parts, for instance, the defense organization largely relies on external partners to deliver 3D printed components. In ord...

One of the disadvantages of modern industrial technologies for laser three-dimensional printing is strong heating at the point of contact of the metal with the laser light beam. This heating melts the metal powder, but it also leads to the appearance of areas of internal mechanical tension and deformation of the workpiece. And all these things are practically impossible to predict, which makes it impossible to somehow compensate for them. However, a team of researchers from the University of Cambridge found a way to solve the problem described above. Using special holographic images generated ...

BASF inaugurated the second phase of its new, world-scale antioxidants manufacturing plant at its Caojing site in Shanghai, China. The second phase comprises a synthesis plant to produce the antioxidants Irgafos®168 and Irganox® 1076. With the completion of the second phase, the plant will have an annual capacity of 42,000 tons, mainly serving customers in China.“When we decided to construct a new plant to support our growing antioxidants business, we sought to build it quickly, safely and efficiently,” said Hermann Althoff, Senior Vice President, Performance Chemicals, Asia Pac...
