In the context of 3D printing, what does the term "layer adhesion" refer to?

Layer adhesion is a fundamental concept in 3D printing that refers specifically to the connection strength between the successive layers that are deposited during the printing process. In additive manufacturing, the printer builds an object layer by layer, and the quality of the final product heavily relies on how well these layers bond to one another.

When layers adhere properly, they form a strong, cohesive structure that can withstand various stresses and strains. If adhesion is weak, the printed part may experience delamination, leading to structural weaknesses and potentially causing part failure during use. Factors such as printing temperature, material properties, and the presence of contaminants can significantly influence layer adhesion.

This characteristic is vital to ensure the integrity and durability of 3D printed components, making it a key focus for engineers and designers in the additive manufacturing field. Understanding layer adhesion helps practitioners select appropriate materials and optimize printing parameters for successful outcomes in their projects.
