The skyline of San Francisco is in the process of significant transformation. Projects such as OMA's 550-foot residential tower, as well as developments in the pipeline from Foster + Partners and Studio Gang, are sure to change the city dramatically - thankfully, the 3D printed model in this video is there to show exactly how. The 6x6 foot model shows 115 blocks of downtown San Francisco as it will appear in 2017, and was created by visualization company Steelblue and Autodesk. Claimed to be the largest 3D printed model of a city in the world, it can show much more than just how San Francisco's downtown will look: overlaid projections can show the status of each building, projected traffic patterns and more. Furthermore, each block is individually replaceable to keep the model up to date. Watch the video, and find out more about the model through this article from SFGate.
