3-D-printed alloys

Posted on Updated on

In the opinion of Lead author and Ph.D. candidate from RMIT University’s School of Engineering, Carmelo Todaro, “the promising results could inspire new forms of additive manufacturing.
If you look at the microscopic structure of 3-D printed alloys, they’re often made up of large and elongated crystals.
This can make them less acceptable for engineering applications due to their lower mechanical performance and increased tendency to crack during printing.
But the microscopic structure of the alloys we applied ultrasound to during printing looked markedly different: the alloy crystals were very fine and fully equiaxed, meaning they had formed equally in all directions throughout the entire printed metal part.”
