The Art of Science: Please Eat the Art

Here at the Finch & Pea, we are big fans of food, art and the scientific method. So when I saw this story about a couple of Media Lab interns at the Metropolitan Museum in New York and their quest to produce edible replicas of museum treasures, I knew I had to share it here. It’s worth reading the whole thing, so please click on over to the Met’s Digital Underground blog for more.

The Art of Science: The Not-Quite-3D Christmas Tree

Little plastic Christmas trees don’t really count as art, but the science and math behind this one is pretty interesting, so we’ll let the deeper questions of aesthetics and meaning slide just this once.

Computer Science researcher Richard Zhang of Canada’s Simon Fraser University printed the tree as a demonstration of a newly developed 3D printing algorithm that has potential applications far beyond seasonal tchotchkes.

Michael Byrne at Motherboard explains:

“Zhang is solving a real-life problem: saving waste. Printing an object with overhanging parts, like a tree branch, requires the deposition of extra material below to support the top part through the printing process. At the end, this material is cut away and trashed. The answer, according to Zhang, is in using pyramidal components.”

“Decomposing a complex shape into simpler primitives is one of the most fundamental geometry problems,” Zhang and his team write in a recent paper. “The main motivation is that most computation and manipulation tasks can be more efficiently executed when the shapes are simple.”

And pyramids offer an elegant solution, because, Zhang says, pyramids are 2.5D.  (I’ll give you a second to collect your brain cells from the floor)

Byrne explains:  “Two-and-a-half dimensions is a concept used in machining (and computer graphics, with a different meaning) to describe an object with no overhangs. It only has a top, and can be viewed as a projection of 2D flatness into the third dimension.”

There’s lots more info about the science and math behind the printable pyramids in Byrne’s article and in Zhang’s paper.

The Art of Science: Biologically-Enhanced Fashion

This is the Björkiest thing I have ever seen.  Wanderers,  a collaborative project to create digitally grown and 3d printed wearables that could embed living matter, looks like a perfect fit for the Icelandic chanteuse, who is famous for her biophilia and wildly adventurous fashion sense.

A team led by Neri Oxman of MIT and Christoph Bader & Dominik Kolb of Deskriptiv is working on a computational growth process which can mimic a wide variety of growing structures.  Based on growth patterns found in nature, computer models create shapes that adapt to their environment.  Once a design is generated, a 3D printer creates a wearable structure.

Filip Visnjic at Creative Applications Network explains: “Starting with a seed, the process simulates growth by continuously expanding and refining its shape. The wearables are designed to interact with a specific environment characteristic of their destination and generate sufficient quantities of biomass, water, air and light necessary for sustaining life: some photosynthesize converting daylight into energy, others bio-mineralize to strengthen and augment human bone, and some fluoresce to light the way in pitch darkness.”

In the long term, the team hopes to produce 3D printed microfluidic devices through which to pump living matter (such as photosynthetic bacteria) to bring the Wanderers to life. In the short term, they’ve created an amazingly hypnotic video showing how the computer simulates growth patterns (watch it here) and some stunning molded plastic breastplates and even a skirt. The pieces, which look a lot like glistening external brains and intestines, are more attractive than I’m making them sound.  And sure, they’re wearable – if you’re Björk.
