Since it is not possible to attach a support material, we use our patented technology of “cross-linking,” in which data is divided and modeled, and each part is joined using the same material used in the modeling process. Because the same material is used, there is no change in material quality, and the integrally processed modeling object has the same strength as the 3D printed modeling object. Please note that the appearance of the cross-linked joints is different from that of normal modeling.
