Printed ABS part strength as compared to molded ABS part strength varies. It all depends on how the parts are printed, how complex they are and how large or small the features are. Also there are several different strengths of ABS for Stratasys/Dimension printers. Some ABS printed parts can have strengths of 80% + of a molded part. You are never really going to match a molded part because the layers of a 3d printed part are it's weakness.
