Quick way to check t quality of 3d-printed alloys
Most 3D-printed metal alloys consist of a myriad of microscopic crystals, which differ in shape, size, and atomic lattice orientation.
By mapping out this information, scientists and engineers can infer the alloy’s properties, such as strength and toughness. This is similar to looking at wood grain, where wood is strongest when the grain is continuous in the same direction.
This made-in-NTU technology could benefit, for example, the aerospace sector, where the low-cost, rapid assessment of mission-critical parts — turbine, fan blades, and other components — could be a gamechanger for the maintenance, repair, and overhaul industry.
In comparison to the current gold standard of using a scanning electron microscope that is expensive and is time-consuming, this fast and easy method of analyzing metal alloys requires only 15 minutes and costs only a fraction of the price.
