David Munson, owner of Munson3D.com, an architectural visualization company, has created a tribute to the terrorist attacks of September 11, 2001, by documenting the totality of the events in a three-piece scale model of lower Manhattan. The model, which he calls “WTC Triptych,” details the cityscape before and after the attacks, as well as what the area will look like when the new World Trade Center buildings are completed come 2013.

The stirring and comprehensive set of models was created via 3D printing.

Munson used 2D satellite images, photographs and 3D models as reference materials to design the cityscapes. Then he used Autodesk CAD software, Google SketchUp and Adobe Photoshop to digitally render lower Manhattan. He then additively built the three models, each 17 x 17-in., on Z Corp.’s Spectrum Z510 full-color 3D printer.

WTC Triptych is now on display at the New York City Fire Museum, to mark the 10^th anniversary of 9/11.
