Why is layer adhesion critical in 3D printing?

Layer adhesion is critical in 3D printing because it ensures the structural integrity of the print. When layers of material are deposited in additive manufacturing, they must bond effectively to one another to create a solid and cohesive final product. If the adhesion between layers is weak, it can lead to issues such as delamination or failure under load, compromising the overall strength and durability of the printed object.

Good layer adhesion allows the part to withstand mechanical stresses, maintain its shape during use, and ensure that it does not deform or break under normal operating conditions. This is especially important for functional parts that may be subjected to forces in real-world applications. Therefore, strong layer adhesion contributes fundamentally to the performance and reliability of the printed item, making it a critical factor in the success of the 3D printing process.
