What is dimensional accuracy?

Dimensional accuracy refers to the degree to which a 3D printed part matches its intended dimensions. In additive manufacturing, achieving accurate dimensions is crucial because it ensures that the final product fits its designated application, whether it be in assembly with other parts or meeting strict tolerances specified in design documents. High dimensional accuracy can affect the functionality and performance of the part, as any deviation from the intended measurements could lead to issues such as improper fitting, reduced safety, or performance failures.

This aspect of additive manufacturing is influenced by various factors including the precision of the printing process, the technology used, and the settings configured on the printer. When dimensional accuracy is confirmed, it assures engineers and designers that the manufacturing process reliably produces components that meet their specifications.
