With 3D printers and CNC machining, there are some specifics that may or may not be available depending on the different process you choose. Tolerances refer to the level of precision that is possible on the specific machine, as well as the maximum amount of deviation that is allowed on a part. Deviation refers to the location, surface, length, width, or other specification of a feature on a part. Use the table below to help you when designing your files for production to make sure you account for possible deviations.
