The F# Journal just published an article about 3D printing:
"The Hilbert curve is a fractal space filling curve. Like many mathematical shapes, Hilbert curves can be used to generate interesting objects for 3D printers. This article describes a simple program to compute and visualize 2D Hilbert curves and use them to generate GCode that, with a little extra effort, can produce nifty coasters for your drinks..."
