ABS also has a higher glass transition temperature, which means the material can withstand much higher temperatures before it begins to deform. This makes ABS a great choice for outdoor or high temperature applications. When printing with ABS, be sure to use an open space with good ventilation, as the material tends to have a slight odor. ABS also tends to contract quite a bit as it cools, so controlling the temperature of your build volume and the part inside can have major benefits.
