ABS is stronger than PLA？
Date of release:2017-12-14 Author: Click:
Although many people will claim that ABS is stronger than PLA, we haven't found them to be substantially different.
PLA is more brittle than ABS and will tend to splinter and break where ABS may tend to bend, but similar force is required for either to fail. It is more likely that you will find your print settings to be a bigger contributor to the strength of printed objects than the plastic you're using (at least between PLA and ABS). Insufficient infill density, too few shells, delamination and related problems may make your object weak even though the material itself is relatively strong.
If your objects feel too flimsy or break too easily try upping infill, adding shells, and tweaking your temperature and speed to try to get better adhesion between layers before you write off your plastic.
