I have provided .stl files if you want to print your own micro chess set. The files can easily be scaled up to larger sizes to create an easier to use chess set. With a little more hand work, they can even be scaled down.
Step 1: How It Works
I am mainly interested in using this process to make very small robots, so I thought making a small chessboard would be a good way to find out the lower size limits of extruder 3D printing.
You cannot simply print out a small object and get consistently good results. It requires modifications in the spacing, number of objects, and printer settings to get crisp 3d prints.
Step1 pic shows the largest chess piece, a king which is .43" high by .1" in diameter. The base and head of the piece is actually hollow.
Step 2: Materials
PLA in one or two colors. I used blue and natural. The natural has the advantage that it is translucent and glows nicely when lit with LEDs.
