Best plastic for gears, splines, etc?

lol and where does he live :-)

The only way to hit 50c in the uk is in an oven.

Might be worth trying polycarbonate or pet though. Both cheaper than polymax and with better stats than abs.

I have been 3D printing a model of a subway car using PolyMax. PolyMax sticks very well to BuildTak. Heating the build platform before removing parts usually work. I need some water-dissolving filament that is compatible with PLA.

As others have said, you can't go wrong with Nylon (http://www.amazon.com/gp/product/B00BGWRYIW).

Or if you're feeling adventurous, give PLA+PHA a try. It's supposed to be stronger than PLA alone (more flexibility) but still uses the same temps as PLA and is biodegradable still.
