Thin-Wall Judgment Logic

As shown below, if there is a thin wall below the machining limit, out of tolerance will occur due to tearing or shape deformation during manufacturing. *If there is an overlap between the limit values, the larger value will be given priority.

If the thin wall is below the limit, the “Quality Agreement” will be displayed on the screen. Please check the relevant area on the 3D viewer and answer whether you agree with tears, deformations and out of tolerance.

If you disagree, we will not be able to provide an automatic quotation. If you disagree but still want the same quality as the model, please write “disagree with the quality agreement” or something similar in the comment box and request a manual quote from meviy support. After that, you will receive an official quotation response shortly.
