Accurately Painting 3D-Printed Objects By Dipping Them in Water

How do you paint a weirdly shaped 3D-printed object with a complex pattern? Take it for a dip in the pool.

A new color technique pioneered by researchers at a computer graphics and visualization lab at Zhejiang University [PDF] involves dipping an object in water while coating it in a multi-colored film. This paints the object in one stroke with zebra stripes, leopard print, or whatever other pattern you might want.

Watch:

It builds on a process called hydrographic painting, which, while similar in concept, isn't terribly effective. The plastic film floated on top of the water, and it was meant to stretch across the dipped object. But it often went awry, creating an inconsistent splash of color or even tears in the paint.

Instead, computational hydrographic printing involves creating a 3D scan of the object (say, a mask) before it's lowered into the water. An algorithm takes into account the way that the plastic film will bend and distort as the object is lowered onto it by a robotic arm, drawing the pattern accordingly. The pattern is then printed out on a regular office printer and then placed on top of the pool of water. The result is a perfectly glued-on pattern, every time.

By dipping the object in the pool multiple times, you can even create a texture to the paint, as if it was painted by hand. (In case you needed to pass off some mass-produced 3D printed wares as homemade Etsy items.)

One Photographer's Quest to Document Every Frank Lloyd Wright Structure in the World

From California’s Marin County Civic Center to the Yokodo Guest House in Ashiya City, Japan, Frank Lloyd Wright’s influence spans countries and continents. Today, 532 of the architect’s original designs remain worldwide—and one photographer is racking up the miles in an attempt to photograph each and every one of them, according to Architectural Digest.

Andrew Pielage is the Frank Lloyd Wright Foundation’s unofficial photographer. The Phoenix-based shutterbug got his gig after friends introduced him to officials at Taliesin West, the late designer’s onetime winter home and studio that today houses the Frank Lloyd Wright Foundation and Taliesin, the Frank Lloyd Wright School of Architecture.

Higher-ups at Taliesin West allowed Pielage to photograph the property in 2011, and they liked his work so much that they commissioned him for other projects. Since then, Pielage has shot around 50 Wright buildings, ranging from Fallingwater in Mill Run, Pennsylvania, to the Hollyhock House in Los Angeles.

Pielage takes vertical panoramas to “get more of Wright in one image,” and he also prefers to work with natural light to emphasize the way the architect integrated his structures to correspond with nature’s rhythms. While Pielage still has over 400 more FLW projects to go until he's done capturing the icon’s breadth of work, you can check out some of his initial shots below.

Inside This Pop-Up Book Are a Planetarium, a Speaker, a Decoder Ring, and More

Designer Kelli Anderson's new book is for more than just reading. This Book Is a Planetarium is really a collection of paper gadgets. With each thick, card stock page you turn, another surprise pops out.

"This book concisely explains—and actively demonstrates with six functional pop-up paper contraptions—the science at play in our everyday world," the book's back cover explains. It turns out, there's a whole lot you can do with a few pieces of paper and a little bit of imagination.

There's the eponymous planetarium, a paper dome that you can use with your cell phone's flashlight to project constellations onto the ceiling. There's a conical speaker, which you can use to amplify a smaller music player. There's a spiralgraph you can use to make geometric designs. There's a basic cipher you can use to encode and decode secret messages, and on its reverse side, a calendar. There's a stringed musical instrument you can play on. All are miniature, functional machines that can expand your perceptions of what a simple piece of paper can become.
