As the plastic filament cools it shrinks slightly causing it to contract. This can cause the curving and layer separation you see above. It tends to be especially bad with long straight sections that end in a sharp corner. There are lots of ways to help prevent this, but as the OP already suggest the best way is to create a build chamber where an even tempeature can be maintained. There are also techniques like adding pads at the corners so it will adheared better to the build platform.

I'm in the process of enclosing my Replicator 2 and adding a heating element to create a heated build chamber to further prevent this sort of warping.
