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...

Dr Daniel Penello, of Alexander Orthopaedic Associates, St. Petersburg, Florida, USA, has successfully implanted what is said to be the US’s first metal additively manufactured finger bone implant. The implant was designed for patient Robert Smith, whose middle distal phalanx was shattered in an ironworking accident in 2017.
