At the dawn of rapid prototyping, a common predication was that 3D printing would transform manufacturing, spurring a consumer revolution that would put a printer in every home. That hasn’t quite happened—-and like so many emerging technologies, rapid prototyping has found its foothold in a surprisingly different field: Medicine.

The following studies and projects represent some of the most fascinating examples of “bioprinting,” or using a computer-controlled machine to assemble biological matter using organic inks and super-tough thermoplastics. They range from reconstructing major sections of skull to printing scaffolding upon which stem cells can grow into new bones. More below—and look out for more 3D printing week content over the next few days.

Israeli prime minister Benjamin Netanyahu was speaking at a government function in July when a man sitting a few rows behind him pulled a Liberator, the infamous 3D-printed gun that the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) recently defined as a “lethal weapon.”

The gun posed no real danger. The man bearing it was just a TV reporter trying to prove how easy it is to sneak a 3D-printed plastic gun past security checks that include metal detectors.

For those who haven’t been following along, this recent story about 3D printing of plastic guns should be a revelation. 3D printing is one of those technologies where the reality is fast outrunning our imagination. It is, in essence, the ability to construct a product from feedstock using a readily available “printer” linked to a computer where the source code for the product is executed. According the Washington Post’s story, the new plastic guns are capable of firing lethal rounds and, naturally, they are beyond the detection of metal detectors.

But for every “parade of horrible story” about 3D printing there’s also one of great promise. For example, NASA recently announced plans to send a 3D printer to the space station. This development, combined with the development of printing for metal objects (from liquid metal feedstock) means that many of our concepts of logistics will go out the window. If a manufacturer can construct metal parts from an easily transported feed stock then, as Andrew Filo, a consultant with NASA on the 3D space station printing project, said: “You can get rid of concepts like rationing, scarce or irreplaceable.” That’s a truly extraordinary development.
