AM technology topologic optimization, create hidden surfaces that cannot be adequately treated for produced rough and defective surfaces. This study presents an experimental evaluation procedure to examine state-of-the-art surface treatments, showing that they do not yet meet that challenge. Additional treatments are being suggested to be further evaluated by the procedure presented in this study.
