I have a problem when printing in ABS.
For some reason, I never seem to get the same results as many other people.
Whereas my prints in PLA, PETG, XT or Nylon all seem to be super strong, my ABS prints all seem to be much weaker. I now that when it comes to tensile strenght and such, ABS IS actually weaker than PLA or PETG, but this what I experience must be something else.
I was printing a model in grey ABS and even while printing, I noticed cracks appearing in the section where the walls get thinner (see picture).
Printing temp was 235 C at first, but I also tried 245. Bed temp is 70 degrees. The ABS flows nicely at both those temps. No fan is used while printing.
When the print is finished I can quite easily pull the prints apart along the print layers? Not only at the places where there are cracks, but even in those places where everything seems fine.
Is there something wrong with my particular type of ABS or am I doing something wrong??
