The resolution of extruded filament 3D printers is really quite high. I used a Makerbot Replicator 2 to make this chessboard, but it should be possible with most low end 3D printers.
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.
