A scaling value of one (1) isequal to 100% of the part in a specific axis. If the part shrinks 1% in a certain axis, the correctanisotropic scaling value would be 1.01 in that axis. The ZPrint Software will display therecommended values for each powder type. The scaling factors may differ according to wall thicknessand geometry of the part.A higher accuracy level may be obtained by measuring the part and adjusting anisotropic scalingvalues as needed. To obtain new anisotropic scaling factors that are part specific, print the part withscaling factors of one (1) in all axes. Once the part is completed, post-process the part. Measure thex-, y-, and z-axes. Divide the nominal value by the measured value. For example, if the printed parthad a nominal value of 1 and had a measured value of 0.98, the scaling value would be 1.02. Aftercalculating the anisotropic scaling values, input them into the software and reprint the part and followthe post-processing procedure.1. Plaster Material SystemThe plaster material system has been found to remain dimensionally accurate during printing andthus, the recommended anisotropic scaling values are one (1) in all axes. If the infiltrant system beingused changes the accuracy of the part, please alter the values as needed.2. Starch Material SystemThe shrinkage found in the starch material system is proportional to the part geometry and the dryingtime of the part. The longer the part is left to dry, the larger the shrinkage value. The part is moststable in the x and y-axis and shrinks more in the z-axis. Thus, the anisotropic scaling factor of the z-axis will always be greater than the values for both the x- and y-axes.3. ZCast Material SystemThe ZCast material system has been found to remain dimensionally accurate during printing and thus,the recommended anisotropic scaling values are one (1) in all axes.
