Frame stiffness just comes down to the shape of the frame and elastic modulus of the material.
On the material side, elastic moduli of drawn and printed titanium are about the same.
On the shape side, a printed frame could be very similar in tube shape and size, or it could be radically different. So far printing has been mostly small tricky bits like brake mounts and tube junctions, which have little to do with overall frame stiffness.
So if the frame shape remains about the same, printed vs tubular ti should have roughly equal stiffness.
