However, whether the part is printed with the prototyping machine or the production model, the resulting object — part plastic binder and part metal — lacks the strength of a metal one. (technologyreview.com)
And if the precollision black holes didn't have the same mass and rotation rate as each other, the waves would have been stronger in some directions than others, giving the resulting object a jolt equivalent to the energy of 100 million supernovae exploding simultaneously, the researchers estimate.

Much of the expense arose from the array of active components that electronically shaped sound waves, manipulating how and where they interfere to create the resulting object - trapping environment just above the array. (sciencedaily.com)
