The paper introduces a methodology for accuracy estimation of micro stereo lithography and micro milling processes. The experimental procedure is a combination of producing simple test parts, routine measurement by optical metrology equipment, and computerised calculations and visualisation by purpose made software. The accuracy and precision of the process are revealed after calculating the linear and shear strains following an approach initially developed for sheet metal forming analysis. The strains in this study are defined on the basis of offset between measured and nominal coordinates of the grid points on the test part. The specific strains of meso-micro parts due to different factors during and after manufacturing are illustrated and explained. Directions for further research are also presented.
