Cracks in ABS

[Sheaffer]

Hi Everyone,

Now that my machine is done, I have started doing some awesome 3D printing. However, I am having a recurring issue that I don't understand how to fix. I am printing with ABS filament at 228C, bed is at 80C. Anything over a few mm has small cracks between some layers. See an example here:

The cracks may be hard to see (I couldn't get a focused shot that close), but you can barely see four cracks on the right hand edge of the tardis and a couple on the left hand side. Any help in determining the cause would be greatly appreciated. Thanks in advance.

ABS tends to do that. You can try printing hotter although you might need a heated chamber in the end.

Would the same thing happen with PLA filament?

Typically not or at least not as easy. PLA doesn't tend to wrap or crack as much as ABS.
