Which issue is often caused by low bed adhesion in FDM printing?

Low bed adhesion in Fused Deposition Modeling (FDM) printing can lead to warpage of the printed object. When the first layer does not adhere properly to the build platform, it may cause corners or edges of the print to lift as the object cools down and the material contracts. This lifting results in warping, which distorts the intended shape of the print and can lead to failure of the entire print.

Warpage is particularly problematic with larger prints or those with significant overhangs and sharp angles. Ensuring good bed adhesion is critical to maintain the object’s integrity throughout the printing process, as it influences how well the material bonds and cools. Factors like print bed temperature, surface preparation, and the type of material used significantly affect bed adhesion and, consequently, the likelihood of warpage.
