This is a to-scale model of downtown Fort Worth. The boundaries are set by the roads, W Belknap St, Jones St, W 7th St, and Bernett St.
The entire city is 3D printed as one piece. It is then attached to a 3/4" hand-cut walnut wood base. The base provides additional stability and a hand-crafted look to the piece.
Each building was modeled 1 at a time for precision. This takes a lot of work but is the best way to ensure an accurate replica of the downtown area. The scale is set at 1:5080, or every 1in is equivalent to 423ft in real life (1mm is 16.6ft). The tallest building in this Fort Worth skyline is the D.R. Horton Tower, also known as City Center Tower II; it is is 547ft in real life, 1.3in in this model (~33mm).
PLA (polylactic acid) is one of the best materials to create objects with a 3D printer. It is a bioplastic made from a number of plant products including corn, potatoes and sugar-beets. PLA is considered an 'earth friendly' plastic that is environmentally friendly and can be composted at commercial compost facilities. PLA can easily be painted with cellulose spray paints and oil paints, although acrylic paints are considered the best choice.
