Which of the following describes a potential defect that may arise from inappropriate cooling practices in printing?

Inappropriate cooling practices during the additive manufacturing process can lead to layer separation. This defect occurs when the layers of material do not adhere properly to one another, which can happen if the cooling is either too rapid or too slow. If cooling happens too quickly, the material may become brittle and unable to bond effectively with subsequent layers, resulting in gaps or separations between them. Conversely, if the cooling is too slow, the previous layers may not have solidified enough to support new layers, leading to sagging or poor adhesion. Layer separation compromises the structural integrity of the printed object and can affect both its mechanical properties and aesthetic appearance. This highlights the importance of having an appropriate cooling strategy tailored to the specific materials and designs being used in the printing process.
