Polycarbonate Material

Does anybody knows if the PC resistance to temperature needs any extra-treatement? Or is it achieved just by printing to the Temperature recommended by manufacturer?

I know polymaker PC recommends baking it for an hour at 100 degrees for extra strength, but I think the temperature resistance should be the same without it

But does it shrink or deform? I'm working on many print parts that will attach into an assembly. If the parts deform, shrink and what have you...that's a lot of wasted prints.

During printing it does indeed shrink, so you have to watch out for warping. @Artiz and myself have been 'playing' with Polymaker PC-MAX recently and shared experiences in this thread: https://ultimaker.com/en/community/22722-polymakers-pc-max-polycarbonate

The purpose of 1 hour annealing @ 100C and subsequent controlled slow cool-down to room temp is to relax the material. What this does is slowly reducing the internal stresses caused by the melting/solidifying process (which is what we do when we print the stuff). In fact this process is not making the stuff stronger, but instead takes away internal stress so that the printed piece will not deform afterwards due to these stresses. So if you need the dimensions to remain unchanged long after printing, you will need to go through this process (of course, heat above glass temp will still deform PC).
