#3d printing

Nina Siegal:

Daniella Levy, who oversaw the day-to-day work on the project for Fujifilm, said: “It’s a one-to-one size reproduction, there’s an exact color match to the original, and it has the exact same brush strokes as the original, meaning the same height and the same direction,” she said. Our challenge was to match the texture of the original in structure and shape. It had to be in perfect registration. It cannot be half a millimeter left or right.”

To create its reproductions, the TU Delft team of researchers, Pieter Jonker, Jo Geraedts and Joris Dik, developed an imaging device to record both color and topographical data from painting surfaces. Tim Zaman, a graduate student, sat for two weeks with Rembrandt’s “The Jewish Bride” in the Rijksmuseum, while it was closed for renovations, and conducted 3-D scans of the painting. The researchers also used X-ray fluorescence to do a chemical analysis of the component parts of the pigments, and hyperspectral imaging, which collects color data from across the electromagnetic spectrum. Combing that information produced a “point cloud,” or a set of volumetric data akin to a three-dimensional pixel. Océ made the high-resolution 3-D print based on the color information it got from TU Delft.

We’re about to enter a whole new world of forgeries.

After test-offering their Replicator 2 printer in Microsoft stores on the West Coast, MakerBot will begin stocking Microsoft stores across the country with 3D printers. The company will also offer demos that allow people to see 3D printing firsthand.

This actually seems like a smart, forward-thinking move by Microsoft. It’s an actual reason to go to a Microsoft Store, and the first move that doesn’t seem like a carbon copy of an Apple Store.

John Markoff of NYT looks at a crazy new wave of microchip/circuit processing:

The emerging printing technology poses a heretical idea: Rather than squeezing more transistors into the same small space, why not smear the transistors across a much larger surface?

And:

Eugene Chow is an electrical engineer who leads the PARC team that has designed the new technology that they have dubbed “Xerographic micro-assembly.” The technology breaks silicon wafers into tens of thousands of chiplets, bottles them as “ink” and then “prints” them, much as a Xerox laser printer puts toner on paper, he said.

Pair this with 3D printing and the possibilities seem insane.

Ellis Hamburger of The Verge reporting on MakerBot founder Bre Pettis presenting at SXSW:

"The MakerBot Digitizer is an innovative new way to take a physical object, scan it, and create a digital file — without any design, CAD software or 3D modeling experience at all — and then print the item again and again on a MakerBot Replicator 2 or 2X Desktop 3D Printer," Pettis said. The Digitizer is capable of scanning objects up to 8 inches by 8 inches in less than three minutes. As the Digitizer scans your object, it spins in a circle on top of a platform. "This is kind of like what happened when Flynn (in Tron) gets digitized into the game grid," Pettis said. "This takes us from being a 3D printer company into being a company that’s building out a 3D ecosystem."

I am extremely bullish on MakerBot and the 3D printing space in general. It just seems so obvious that this is the way we’re going to create a lot of things in the not-too-distant future.
