Which of the following is a potential drawback of using ABS over PLA in 3D printing?

The potential drawback of using ABS over PLA in 3D printing is that ABS tends to experience more warping during the cooling process. This is primarily due to the thermal properties of ABS, which has a higher coefficient of thermal expansion compared to PLA. As the ABS cools, it can shrink unevenly, leading to warping and potential detachment from the print bed. This behavior often necessitates the use of a heated print bed and careful temperature management to mitigate the warping effects.

In contrast, PLA is more stable during the cooling phase, resulting in less warping and making it easier to print for beginners or in settings where temperature control is limited. Understanding these material properties is crucial for selecting the appropriate filament based on the requirements and constraints of a 3D printing project.
