How Jeff Koons Made A Perfect Replica of Our Imperfect “Liberty Bell” – from Vanity Fair:

…Liberty Bell differs from Koons’s sculptures in one significant way: it is a near-perfect replica of an imperfect object. When making a faithful reproduction, Koons will often distort some other feature, like size (think: giant balloon dogs) or surface (giant, mirror-polished balloon dogs). His work also traffics in composite ideals—to create his eight-foot Balloon Venus he inflated and tied hundreds of balloons so that he could select the perfect buttocks, breast, and head of each. Liberty Bell is anything but ideal; in fact, the object’s most well-known feature is its flaw. 

Koons was given after-hours access to the Liberty Bell, in Philadelphia, to conduct structured-light scans. Performed by Direct Dimensions, the scans work by projecting a known pattern onto an unknown surface and measuring the distortions. (This is significantly less detailed than C.T. scans—generally used to capture all the external and internal data, of, say, a brain tumor—which Koons has begun using for his “Balloon” series. But he couldn’t very well disassemble a national treasure.)    

The point cloud data from the structured-light scans were stitched together and converted into a 3D computer rendering at Koons’s studio. All variety of CAD (computer aided design) software, such as Rhino, is used to manipulate those renderings, and some data sets are so complex that simply processing them can take up to a year, as was the case with Koons’s Pink Ballerina, a yet unfinished work five years in the making….

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!

Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!

The Adafruit Learning System has dozens of great tools to get you well on your way to creating incredible works of engineering, interactive art, and design with your 3D printer! We also offer the LulzBot TAZ – Open source 3D Printer and the Printrbot Simple Metal 3D Printer in our store. If you’ve made a cool project that combines 3D printing and electronics, be sure to let us know, and we’ll feature it here!

Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here:
