I doubt you could do anything to a bike frame with this that you couldn't with foam-core carbon fiber. The advantage 3d printing over CFRP is cost is constant with intricacy and number of joints. That means its best for skeletonizing to a small scale or lightening really intricate parts, and expensive for large, sweeping parts (like the shape of a frame). So, you could skeletonize things like brake levers/mechanisms to a much higher degree than with older aluminum alloys. The ultimate limit to skeletonizing something is the tensile strength since each member basically becomes a wire eventually. At that point its strength is determined by the tension it can sustain rather than the bending force.
