What is the tolerance of laser cut parts?

The tolerance of laser cut parts typically ranges from +/- 0.002 inches to +/- 0.05 inches, depending on various factors such as part size and feature complexity. For most standard-sized parts, Fabworks maintains an overall cutting tolerance of +/- 0.005 inches, which ensures high precision and accuracy in the final product. This tight tolerance is achievable due to the advanced fiber laser cutting technology employed by the company.

When it comes to specific features like holes and slots, the tolerance can be even tighter, often reaching +/- 0.002 inches. This level of precision is particularly beneficial for parts that require exact fits or intricate designs. However, it's important to note that larger parts or features located far apart may experience slightly wider tolerances.

For features or dimensions that span more than 30 inches, the tolerance may increase to +/- 0.005 inches. This slight increase is primarily due to the heat distortion that occurs during the fiber laser cutting process. As the laser moves across larger areas, the heat generated can cause minor expansions or contractions in the material, leading to slightly wider tolerances.

It's worth mentioning that these tolerances are generally tighter than many other manufacturing processes this fast, making laser cutting an excellent choice for projects that demand high precision. The consistency and repeatability of laser cutting also contribute to maintaining these tight tolerances across production runs.

Understanding these tolerance ranges is crucial for designers and engineers when creating parts for laser cutting. It allows for proper planning and design considerations, ensuring that the final product meets the intended specifications and fits correctly in its intended application.
