Another small scale model of Washington, DC downtown area CNC router cut from Google Earth data, this time in a higher density urethane foam material. The result is WAY better detail and smoothness than in MDF, and accordingly, an order of magnitude increase in material cost, although some savings can be realized in faster machining times. The final sculpture is going to be 5’ x 13’ in size, and sanding and finishing all those little surfaces in MDF would be an absolute nightmare in both the actual work and the man-hours to pay for it all. This is going to be sprayed with a high build primer in an auto-body shop, followed by a proper paint job. A classic example of “you get what you pay for”
