An architectural CAD expert has created a tribute marking the 10th anniversary of 9/11, pooling his expertise in 3D design tools and 3D printing to document Ground Zero before, during, and after the terrorist attacks.
The three-part 3D printed model, "WTC Triptych," was created by David Munson, a specialist in using visualization and computer technology to recreate precise and complex architectural representations. Munson's company, Munson3D, works regularly with companies and cities on building and urban planning projects. He got the idea for the 3D printed Ground Zero sculpture a couple of years ago, when he met a Port Authority worker at a 3D printing conference.
David Muson's detailed three-part model "WTC Triptych," created with ZCorp's ZPrinter, is now on display at the New York City Fire Museum.
The project was launched with the idea of courting the Port Authority of New York and New Jersey as a client, with Munson pitching the agency on creating a highly realistic, color 3D printed model of the new towers as they were being built. That initial project never got formally got off the ground, so Munson decided to move forward on his own. He began conducting the research and gathering the data necessary for building an accurate 3D representation of the Ground Zero site.
"Part of my interest was in putting the possibilities out there of what could be done with 3D printing technology," Munson said in an interview. "But when I starting thinking about the site depicted in a before, during, and after [context], I realized I could tell the story of the connection between all three."
He says the "WTC Triptych" project was a labor of love, especially considering how much work gathering the data was, in particular. To piece together the three depictions of the World Trade Center site, he drew on numerous data sources, including 2D satellite imagery, Google Earth, photographs downloaded from the Internet, and publicly available 3D models and images found on Wikipedia. Because the images were not from one particular source, he had to cross-check graphic sources to confirm various figures, including important dimensions like building heights.
Not only was the data collection laborious, but fine tuning the data models so a 3D printer could reproduce them accurately was another big challenge. Munson used Autodesk 3dsMax Design 3D software in addition to AutoCAD, Google SketchUp, and Adobe Photoshop to create the models and do the complex texture mapping and geometry cleanup that was necessary for outputting a 3D printed model in realistic color. ZCorp, which collaborates with Munson regularly for his visualization consulting business, donated the ZPrinter 3D printing capabilities to output the final model.
Munson says he's proud that his 3D model is on display at the New York City Fire Museum and will be on hand for the 10th anniversary tribute. "It's really humbling to be there" at the museum, he said. "Those guys put everything on the line."
One of the great things about technology is that it keeps evolving. We have created a 3D printer that uses subtraction techniques to dramatically reduce the time to print (on average about 1/20th that of additive machines) and more importantly, the cost. With our materials as low as $0.06/in^3, we have made 3D printing affordable. Check out 2BOT.com
Yes, I think you're right, Jack. I do believe there's a fair amount of knowledge and effort required in terms of scanning and manipulating the 3D image of the to-be-printed component in CAD or another 3D type of design tool. I think that's where we'll see a lot of activity over the next few months/years in terms of making the software more accessible for use by non-engineers coupled with less expensive, more off-the-shelf, packaged scanners/3D printers. Should be exciting.
Yes, that's the video I had in mind. I figured that it wasn't showing everything. There's got to be a fair amount of manipulation of the "scanned" image to specify the moveable parts.
@Jack: Is this the video you're talking about? If so, yes, Munson's 3D printed Ground Zero sculpture is produced using the similar 3D printing technology from ZCorp. It is truly amazing what's being done with this technology, although it is a bit more complex than comes off in this video.
Slightly off topic, but is the technology used in his 3D printer the same that is used in that video of the 3D scanner that's been floating around the internet? If so, not only is this a great tribute, it is also a lasting one. (For those who haven't seen the "scanner" video, they scan a crescent wrench and make a somewhat usable copy).
Munson's 3D depiction of Ground Zero stands among the many noteable ways America remembered the events of 9/11 and the 9/11 victims this weekend. I applaud all of the time and effort he poured into making this sculpture happen and his commitment to ensure that it was part of the formal remembrance. While the many photos and digital clips keep the event etched in our memories so too does this 3D visual map which shows just how much New York City and the rest of the country lost that fateful day.
UK-based Plastic Logic and French company ISORG have created what the pair tout as a first in flexible printed electronics: a large area, conformable, organic image sensor printed on plastic.
For 3D printing to make the jump from rapid prototyping to manufacturing, engineers will need to find easier ways to move products from their CAD screens to their printers.
Gigabit and PoE are two networking technologies moving ahead in tandem as industrial users power remote Ethernet devices such as IP security cameras at 1,000 Mbps over existing CAT5 cable.

For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
