The hobbyist 3D printers have pretty much overtaken the production quality of commercial filament fed printers. The model I'm getting has reliably produced objects with a 90 micron print layer and some of the cartesian printers (Makerbot, RepRap, etc) have gone down to as little as 50 to 10 microns. If you have the specs on the gears, it would be pretty simple to print a few and see how they hold up. g. -- Proud owner of F-15C 80-0007 http://www.f15sim.com - The only one of its kind. http://www.diy-cockpits.org/coll - Go Collimated or Go Home.
