+1 0 -1 Simple answer is: It depends. I am actually surprised your PLA testprint would bend so easily compared to ABS. PLA is normally speaking both stiffer than ABS, it's surface is much harder and the tensile strength of PLA is about twice (2x times) that of ABS. The main advantages of ABS are it's higher temperature resistance and the much higher impact resistance. PLA has a very low impact resistance, which means it will break rather quickly under sudden stress whereas ABS will tend to 'give' under similar circumstances. You can 'anneal' most PLA-brand in an oven which will make it stronger AND increase it's temperature resistance significantly. More specifically, brands like 3D Fuel A-PLA, Fiberloggy HD-PLA, Innofill PRO1 or FormFutura Volcano-PLA are all ment to be annealed after printing, increasing both strength and temperature resistance up to 140 degrees Centigrade. That said, annealing prints WILL cause some shrinking in your object. FormFutura Volcao-PLA is claimed to suffer the least in shrinking, but after annealing, its temp resistance is on par with ABS. Please do remember that though strenght is increased by annealing, the impact strength does not seem to alter much and remains lower than that of ABS. I would suggest you try PETG as a good alternative to both PLA and ABS. I just finished printing a children's made entirely from PETG apart from the TPE tires and a few metal parts like the wheel axles, some nuts and some Z608 bearings.
