Since 3-D printing technology has become more accessible, the magic of manifesting an object before your eyes has yet to lose its luster. When Dewar’s decided to create a sculpture to mark the launch of its Highlander Honey whiskey, however, it took the concept of 3-D printing to a whole new level, employing the services of nature’s original three- dimensional crafters: bees.

Through an un-usual DNA collection method, American artist Heather Dewey-Hagborg creates portrait sculptures from the analyses of genetic material collected in public places. From cigarette butts to hair samples, she works using random traces left behind from un-suspecting strangers. In a statement by Dewey-Hagborg, ‘Stranger Visions’ calls attention to the impulse toward genetic determinism and the potential for a culture of genetic surveillance. Using DNA facial modeling software and a 3D printer, physical models are conceived – reconstructed from ethnic profiles, eye color and hair color.

Earlier this year, someone took 3D printing to the logical, if extreme, next step: weapons. The 3D printing gun idea has taken off, but Stratasys, the company that makes the printers being used, isn’t exactly happy about it. They want their printers back.
A few months ago, on a gun forum, someone with the username HaveBlue posted pictures of an AR lower that he printed using a Stratasys 3D printer. Eventually he assembled a .22 caliber pistol using that lower. Not only did he print it, he shot it. And it worked. He writes, “No, it did not blow up into a bazillion tiny plastic shards and maim me for life – I am sorry to have disappointed those of you who foretold doom and gloom.”

“On the path to get the perfect 3D-Print, many meters of filament get piled up as discarded disappointments, as bastard objects that never were, as unborn half-things…and they are beautiful.”
At normal listening distances, an array of twelve speakers arranged on the faces of a dodecahedron is a very good approximation of a point sound source, and the sound waves it produces are very close to perfectly spherical. A dodecahedron speaker can be a useful tool in acoustics research, and is definitely a fun toy to pull out at parties. They are available commercially, but very expensive. Some people build their own, but the odd compound angles and the high degree of accuracy and precision required in the parts make for challenging work with manual tools. But it’s easy for a 3D printer.

Lawrence Bonassar, Ph.D., Associate Professor of Biomedical Engineering, describes a cutting-edge process he has developed in which he uses a 3D Printer and “ink” composed of living cells to create body parts such as ears.
