3D printed titanium substrates mainly include TA1G~TA2G, TC4,TC4 ELI,NiTi(NiTi-01M),TA15,TC11,TC18,Ti80(Ti6Al3Nb2Zr1Mo),Ti1023(Ti10V2AI3Fe),Ti4822(Ti48Al2Cr2Nb),Ti6242(Ti6AI2Sn4Zr2Mo) Wait, with high surface smoothness and precise dimensions, the positioning reference and clamping of the substrate are completed by the zero position clamping screw or clamping pin on the bottom surface.
