Minecraft Map of Northwestern Campus Printed In 3D 70

erich666 writes "Ben Rothman has created a five-foot-wide scale model of most of Northwestern University, where he was a sophomore this past year. This campus model is unique: it is the first modeled in Minecraft and then printed on a 3D printer. It is also the largest Minecraft 3D print to date, and will be on display in the main lobby of the largest building on campus in a few weeks. Ben began in November and spent about 600 hours recreating the campus. He notes that "this felt like playing a game more than a modeling task." The cost of the print material was about $2000 to $2500, well less than the cost of the display case being built for it (admittedly, labor costs are included for the case). The free Mineways program was used for export. It can help upload an exported Minecraft model to Shapeways, i.materialise, or other 3D print service. Models cost as little as $5."

MIT Professor Pushes the Envelope of 3D Art and Manufacturing 58

kkleiner writes "Professor at MIT Neri Oxman's creations are demonstrating the powerful combination of 3D printing and new design algorithms inspired from nature. Just as a computer printer makes copies of 2D images, 3D printers have copied an impressive variety of objects, such as robots, chairs, prosthetics, kidneys, and jaw bones, to mention a few. But Oxman and her colleagues are discovering new design and engineering principles that will help to mature 3D printing into a technology capable of producing complex and beautiful structures impossible by other manufacturing techniques."

Ask Slashdot: Best Option For Printing Digital Photos? 350

rrossman2 writes "With the birth of our son (who is now just over two), we have snapped and accumulated a ton of pictures — on Panoramio, Picasa, Facebook, etc. What is the best option for bulk printing the photos to a physical format? We all know how fast technology advances, as well as how fast sites come and go; I want a way to have these pictures for my son when he is older... just like my grandfather has photos of himself from World War II, my parents have photos of me when I was little, etc. Are there any affordable services that you can upload the photos to that print and deliver long-lasting pictures? How well do today's photo ink jets last, and what's the best type of paper? I do have a cheaper Samsung color laser printer, but color lasers don't make the most color-rich prints, and using normal photo paper you can find in big box stores doesn't work out too well, as the laser toner seems to peel off on the rollers and gum things up. (Is there a good long lasting paper that seems to work well with laser printers?) I can see what's going to happen in the future: all of the digital photos people take now are going to either end up on a website that won't be around in 20+ years, or get stuck on disks or flash memory that won't last, or for which interfacing with the media will become difficult or impossible."

3D-Printed Circuit Boards, For Solder-Free Printable Electronics 106

An anonymous reader writes "Check out the latest success of the OpenSCAD 3d-printed electronics library. To use it, you just need a 3D printer and some conductive thread. OpenSCAD generates a component holder, and conductive thread wraps it all together — no solder, no etching chemicals, no sending out for anything. The instructable takes you through all the steps from schematic to circuit, and includes a more useful example: the fully printed LED flashlight."

IBM Sells Point-Of-Sale Business To Toshiba 120

ErichTheRed writes "Yet another move by IBM out of end-user hardware, Toshiba will be buying IBM's retail point-of-sale systems business for $850M. Is it really a good idea for a company defined by good (and in this case, high-margin) hardware to sell it off in favor of nebulous consulting stuff? 'Like IBM's spin-offs of its PC, high-end printer, and disk drive manufacturing businesses to Lenovo, Ricoh, and Hitachi respectively in the past decade, IBM is not just selling off the RSS division but creating a holding company where it will have a stake initially but which it will eventually sell.' Is there really no money in hardware anymore? "

Print Your Own Labware, Catalysts Included 33

scibri writes "Chemists have found a way to make reaction vessels perfectly suited to their needs, with 3D printers. From the article: 'Armed with a three-dimensional printer and the type of silicone-based sealant typically used for bathrooms, researchers have demonstrated a novel way to control chemical reactions ... One vessel was printed with catalyst-laced "ink," enabling the container walls to drive chemical reactions. Another container included built-in electrodes, made from skinny strips of polymer printed with a conductive carbon-based additive. The strips carried currents that stimulated an electrochemical reaction within the vessel.'"

Restoring China's Forbidden City With 3-D Printing 46

First time accepted submitter jcho5 writes "China's 600-year-old Forbidden City is looking less forbidding these days. As part of a major restoration, the Chinese Palace museum will use 3D-Printers to re-manufacture and replicate many of the city's most precious and unique objects. From the article: 'PhD student Fangjin Zhang—along with her colleagues at Loughborough Design School in the East Midlands of England—had, for a number of years, been looking into the use of 3D printing as means to restore sculptures and archaeological relics. According to a Loughborough press release, Zhang developed a “formalized approach tailored specifically to the restoration of historic artifacts.” After reviewing Zhang’s techniques, the Palace Museum then invited Loughborough researchers to repair several Forbidden City artifacts, including the ceiling and enclosure of a pavilion in the Emperor Chanlong Garden.'"

Lab and Sy-Lab have officially released their Free Universal Construction Kit, allowing builders to freely interconnect parts from Lego, K'Nex, Fischertechnik, and other common building sets. ZomeTool and Zoob patterns will be available after related patents expire. The makers have also spent considerable effort investigating and anticipating legal complaints from manufacturers, using an Inverse Think of The Children Argument: Some may express concern that the Free Universal Construction Kit infringes such corporate prerogatives as copyright, design right, trade dress, trademarks or patents of the supported toy systems. We encourage those eager to enforce these rights to please think of the children — and we assert that the home printing of the Free Universal Construction Kit constitutes protected fair use." Model files are available over at Thingiverse. The designs are all covered by the CC BY-SA 3.0.

The Laser Unprinter 168

MrSeb writes "You've heard of laser printers — and now a team of researchers from the University of Cambridge in England has created a laser unprinter that can remove ink without damaging the paper. Despite both methods using lasers, their (un)printing approaches are fundamentally very different. In a laser printer, a laser is used to give individual 'pixels' on a piece of paper a positive charge (a separate heat source is used to fuse toner). In the laser unprinter, picosecond pulses of green laser light are used to vaporize the toner, or ablate in scientific terms. The primary goal of unprinting is to cut down on the carbon footprint of the paper and printing industries. Manufacturing paper is incredibly messy business, with a huge carbon footprint. Recycling paper is a good step in the right direction, but it still pales in comparison to unprinting. In a worst-case scenario, The University of Cambridge unprinting method has half the carbon emissions of recycling; best-case, unprinting is almost 20 times as efficient."

Nanoscale Race Car Gets 3D Printed With a Laser 39

An anonymous reader writes "Researchers at the Vienna University of Technology have managed to perfect 3D printing at the nanoscale. What may look like a grain of sand to the human eye could in fact be a detailed racing car model, a reproduction of a famous church, or London Bridge. The 3D printer relies on a laser beam directed by mirrors through a liquid resin onto a surface. It can print at 5 meters per second, which is a world record, and the end result is only a few hundred nanometers in size. The next hurdle: printing with bio-material so we can start making our own body parts/organs."

Torvalds Calls OpenSUSE Security 'Too Intrusive' 311

jfruh writes "The balance between security and ease of use is always a tricky one to strike, and Linux distros tend to err on the side of caution. But no less a luminary than Linus Torvalds thinks openSUSE has gone too far. When his kid needed to call from school for the root password just so he could add a printer to a laptop, that's when Linus decided things had gone off the rails."

With Push for OS X Focus, CUPS Printing May Suffer On Other Platforms 267

CUPS is the popular open-source printing system that many projects have used successfully as a core, for desktop printing and as the basis of dedicated print servers. Reader donadony writes with word that Apple "has chosen to abandon certain Linux exclusive features, [while] continuing with popular Mac OS X features. The changeover is being attempted by Apple to set new printing standards that will not require 'drivers' in the future." However, as this message from Tim Waugh at Red Hat points out, all is not lost: "Where they are of use for the Linux environment, those orphaned features will continue to be maintained at OpenPrinting as a separate project."

FOIA Request Shows Which Printer Companies Cooperated With US Government 355

New submitter Dave_Minsky writes "The U.S. Secret Service responded to a FOIA request on Monday that reveals the names of the printer companies that cooperate with the government to identify and track potential counterfeiters. The Electronic Frontier Foundation revealed in 2005 that the U.S. Secret Service was in cahoots with selected laser printer companies to identify and track printer paper using tiny microscopic dots encoded into the paper. The tiny, yellow dots — less than a millimeter each — are printed in a pattern over each page and are only viewable with a blue light, a magnifying glass or a microscope. The pattern of dots is encodes identifiable information including printer model, and time and location where the document was printed." Easy enough to avoid government dots; just don't buy printers from Canon, Brother, Casio, HP, Konica, Minolta, Mita, Ricoh, Sharp, or Xerox.

Best Practice: Travel Light To China 334

Hugh Pickens writes "What may once have sounded like the behavior of a raving paranoid is now considered standard operating procedure for officials at American government agencies, research groups and companies as the NY Times reports how businesses sending representatives to China give them a loaner laptop and cellphone that they wipe clean before they leave and wipe again when they return. 'If a company has significant intellectual property that the Chinese and Russians are interested in, and you go over there with mobile devices, your devices will get penetrated,' says Joel F. Brenner, formerly the top counterintelligence official in the office of the director of national intelligence. The scope of the problem is illustrated by an incident at the United States Chamber of Commerce in 2010 when the chamber learned that servers in China were stealing information from four of its Asia policy experts who frequently visited China. After their trips, even the office printer and a thermostat in one of the chamber's corporate offices were communicating with an internet address in China. The chamber did not disclose how hackers had infiltrated its systems, but its first step after the attack was to bar employees from taking devices with them 'to certain countries,' notably China. 'Everybody knows that if you are doing business in China, in the 21st century, you don't bring anything with you,' says Jacob Olcott, a cybersecurity expert at Good Harbor Consulting. 'That's "Business 101" — at least it should be.'"

83-Year-Old Woman Gets New 3D-Printed Titanium Jaw 121

arnodf writes "The University of Hasselt (in Belgium) announced today (Google translation of Dutch original) that Belgian and Dutch scientists have successfully replaced an 83-year-old woman's lower jaw with a 3D-printed model. According to the researchers, 'It is the first custom-made implant in the world to replace an entire lower jaw. ... The 3D printer prints titanium powder layer by layer, while a computer controlled laser ensures that the correct particles are fused together. Using 3D printing technology, less materials are needed and the production time is much shorter than traditional manufacturing. The artificial jaw is slightly heavier than a natural jaw, but the patient can easily get used to it."

Ask Slashdot: Wireless Proximity Detection? 101

New submitter Cinnamon Whirl writes "As a chemist, I work in a both lab and office enviroments, and need access to data in both, without causing undue clutter in either. My company has recently purchased two Win7 tablets for trial usage with electronic lab notebooks, propietry software, SAP, email etc. These are also useful for sharing in meetings, etc. As part of this project, I have been wondering whether we can use these tablets to detect other devices by proximity. Examples could include finding the nearest printer or monitor or, perhaps trickier, could two roaming devices find each other? Although lab technology is rarely cutting edge, I can see a day when all our sensors and probes will broadcast data (wireless thermocouples are already available), and positioning information will become much more important. What technologies exist to do this? How accurate can the detection be?"

Pirate Bay To Offer Physical Item Downloads 343

lukehopewell1 writes "The Pirate Bay is offering users the chance to download and print out real objects using 3D printers in what the pirate site is hailing as 'the future.'" Amir Taaki mentions that among the new "physibles" uploaded to the Pirate Bay are "plans for a tabletop replica for a Warhammer 40k dreadnought that got taken down in December with a DMCA request." Downloadable 3D models have been around for a while; MakerBot users are probably all familiar with the Thingiverse. Couple TPB with a cheap method of accurate 3D scanning, though, and I wonder what illegal shapes will emerge.
