Assembly Tolerance Assembly tolerance refers to the intentional gap or allowance between parts of a 3D-printed assembly to ensure they fit together properly. Tolerances account for variations in printer accuracy, material shrinkage, or design inconsistencies. For example, a tight tolerance may result in parts that are difficult to assemble, while an overly loose tolerance may cause instability. Designers often include features like snap-fit joints, slots, or pins to aid in alignment and ensure proper functionality. Accurate tolerances are critical in engineering, robotics, and product design, where parts must meet strict specifications for performance and reliability. |
