I was wondering if there are any suppliers of Printed Parts for the Prusa here in Australia and also what type of threaded rods are available here?

Thanks
Paul

Metric is the standard for threaded rod here, although you will find SAE around as well at places like Bunnings (don't use Bunnings rod though, it's galvanized steel which looks terrible and jams in the nuts).

There's a list of Australian suppliers on the wiki:

Personally I've bought BZP rod from both Keables and Metro Bolts and they've both worked well, although the stuff from Cost Less Bolts looked good too. Most important thing to make sure it's really straight when you buy it because even a small wobble can cause the sides of your printed pieces to oscillate slightly every 3 or 4 layers.

BZP means Bright Zinc Plated, and is usually only threaded rod. BZP also tends to be only 'mild steel' which can be bent fairly easily.

I personally use 304 grade stainless steel for all my smooth and threaded drive rods (anything that is driven as a moving part by a motor, such as the Z rods). It's almost always straight (mainly as it's stronger, and doesn't bend as easily), which avoids problems later.
