从加利福尼亚州圣地亚哥出来，SD3D打印has slowly cultivated popularity with services such as their Printer Farm,which we covered back when it began operating around 2014. Equipped with both 3D printing power and a group of eager entrepreneurs, SD3D has just completed what could be their most ambitious project yet. Teaming up withaonSD3D是风险管理，保险和其他少数服务的全球领先提供商之一，仅设计和印刷了最大的3D印刷城市迄今为止。这座城市称为Aon Town，尺寸高达9 x 10.5英尺，SD3D总共花了六周的时间来建模和打印每栋建筑，街道和树木。
Starting with a 2D drawing, SD3D utilized Rhino design software to bring the city into the three dimensional world. The design work alone took over 200 hours to complete. Once the team was finished with modeling the city, they began 3D printing it in 9 x 9 inch squares, while printing the taller skyscrapers in sections. Before the trees, plants, skyscrapers, and other features were even printed, SD3D had already constructed over 300 quadrants. After about 3,000 hours of printing time on over a dozen 3D printers— which included both theLulzbot TAZSD3D制造了专有的内部打印机，并穿过大约60公斤塑料材料的塑料材料。
大部分城市都印在孵化箱White PLA, aside from the road (grey PLA), plants (green PLA), cones (red PLA), and water (blue PLA). To assemble the city, SD3D first glued the main quadrants together, then began to implement the smaller features as they went along. The team also constructed a mini-city as well, which was scaled down about 1/3 the size of the full-sized model. Though the idea of 3D printing a city this large has enough merit on its own, there was a purpose for both Aon and SD3D to get involved with the project.
For Aon, the city helped to give consumers a visual representation of the vast services that Aon has to offer. For instance, one particular section features two skyscrapers, which were equipped with acrylic cutouts, showcased a board meeting to advertise their insurance programs for mergers, private risk management, and other commercial activities. In total, the city displays 29 different areas that Aon can provide for potential clients, For SD3D, the point of the project was to showcase just how much they could accomplish with their 3D printing services. Though I’ve yet to see this miraculous 3D printed city myself, I feel confident enough to say that SD3D did indeed prove their 3D printing capabilities with the Aon town project.
