'Frankenstein design' enables 3D printed neutron collimator
The time-tested strategy of "divide and conquer" took on a new, high-tech meaning during neutron experiments by scientists at the Department of Energy's Oak Ridge National Laboratory. They discovered that the problems they faced while attempting to 3D print a one-piece collimator could be solved by instead developing a "Frankenstein design" involving multiple body parts—and some rather obvious scars.
