How a genuine object will interact with its surroundings is significantly influenced by its roughness. In tribology, rough surfaces often have greater friction coefficients and wear more quickly than smooth surfaces. Since surface irregularities may serve as initiation locations for cracks or corrosion, roughness is frequently a reliable indicator of how well a mechanical component will operate. Roughness, on the other hand, might encourage adherence. In general, cross-scale descriptors like surface fractality offer more accurate predictions of mechanical interactions at surfaces, such as contact stiffness and static friction, than scale-specific descriptors.

High roughness values are frequently undesirable, yet they can be challenging and expensive to regulate in manufacturing. For fused deposition modelling (FDM) made parts, it is difficult and expensive to manage surface roughness. A surface’s production cost often increases as its roughness decreases. This frequently leads to a trade-off between a component’s manufacturing cost and its application performance.
