What does good layer adhesion in FDM printing help to ensure?

Good layer adhesion in Fused Deposition Modelling (FDM) printing is crucial for ensuring increased print strength. When layers bond effectively during the printing process, the resulting object has greater structural integrity. This is because the layers act as a single cohesive unit rather than separate segments, reducing the likelihood of delamination, which is when layers separate from each other under stress.

The strength of a printed part is directly impacted by how well each layer adheres to the one below it. Strong adhesion allows the material to withstand mechanical loads, impacts, and other forces that might be applied during its use. Proper layer bonding contributes to the durability and longevity of the parts, making them suitable for various applications.

While good layer adhesion can influence other factors such as flexibility or the overall efficiency of the printing process, the primary benefit it provides is the enhancement of print strength, making it a foundational principle of effective FDM printing.
