Reproducing tiny plastic gears for vintage 'gear'

[Martin Hepperle]

BTW: commercial 3D printing services often offer Nylon as a material to laser-sinter parts. These are made from a fine Nylon powder which is melted layer-by-layer by a laser beam.

This process produces very rugged parts, but these have a slightly rough surface finish (like maybe 200 grit carborundum paper). If you need heavy duty parts, this may be a solution, even if it a bit more expensive. But not for very small gears.
