It’s usually the accepted tolerance during manufacture of + or - a certain amount. For instance; it might have a printing accuracy of + or- 0.02mm meaning there could be some variance in the filament quality and thickness within the figures stated. This could then in turn affect the quality of the printed item within the same parameters. The thing to look for is a lower + or - figure which would then suggest better accuracy. Hope that’s helped.
