The actual printing process itself involves a two photon polymerization where the photosensitive resist cures in the exposed areas and can later be removed in a bath of developing chemicals. While the process will require much more study and refining before they begin trials with humans, it’s thought that this has the potential to be much more effective than other routes such as artificial insemination or in-vitro fertilization, which have very low success rates. What the researchers are seeing in the lab so far is very promising—and could certainly change the lives of many—as well as helping to create many more.
