Remaining Issues in "An Analytical Foundation for Optimal Compensation of Three-Dimensional Shape Deformation in Additive Manufacturing"

Optimal Compensation Policy to Reduce Maximum Shape Deformation

      Optimal compensation policies established in "An Analytical Foundation for Optimal Compensation of Three-Dimensional Shape Deformation in Additive Manufacturing" satisfy the Minimum Area Deviation (MAD) Criterion or the Minimum Volume Deviation (MAD) Criterion respectively. The polices will reduce the average shape deformation for 2D or 3D shapes. 
     If maximum shape deformation of a product should be less than a pre-specified value, a MinMax criterion will be more appropriate. However, currently no MinMax optimal compensation policy has been established for 3D shape deformation.
    A more complicated case is the combination of MAD and MinMax criteria, which is more realistic for practical case.  More research is needed to address the remaining issues left in "An Analytical Foundation for Optimal Compensation of Three-Dimensional Shape Deformation in Additive Manufacturing" (ASME-JMSE, in press).
