We're increasingly seeing 3D-printed metal components being used in fields such as aviation, where failures could be catastrophic. It's therefore very important to check those items for structural flaws before they're installed, and the best way of doing so may involve freezing them in ice.
Because such parts are manufactured (in most cases) by depositing or melting successive layers of metal, the inspection of the solid material can only be performed once the parts have been made. By contrast, when parts are more traditionally machined out of a solid block of metal, it's relatively easy to first check that block for cracks or other faults by running ultrasound waves through it …………….
