Why is accurate dimensionality important in FDM prints?

Accurate dimensionality in FDM (Fused Deposition Modeling) prints is crucial for maintaining part functionality. When a printed component is not dimensionally accurate, it may not fit together with other parts or parts may not perform their intended functions. Precision is vital in various applications, including mechanical assemblies, where even minor inaccuracies can lead to issues such as misalignment, binding, or inadequate interfacing.

In engineering and functional parts, dimensional accuracy ensures that the parts work as designed under the expected conditions. For example, components that fit into tight tolerances or that require precise movement will fail to function correctly if they are inaccurately printed. Therefore, ensuring the correct dimensions not only affects the structure but also impacts the performance and reliability of the final product.
