Another innovative use for 3D printing has appeared as reported by Today and Tomorrow. PRINT magazine commissioned a cover from Artist Karsten Schmidt, who:

used the Gray-Scott reaction diffusion model in a Processing sketch (an open source programming language) to generate a 3D typographical model.

While this project was intended as a magazine cover, printing of 3D signs could be a popular practice on future home-based 3D printers. The issue with signs, obviously, is that the letters don't necessarily touch each other, and thus a way of structuring the design to support the message is required. Karsten Schmidt's approach is a unique way of solving the problem.
