as an avid cyclist and certified 3Dprinting Nerd, I would say, It probably could be with the right design but I am not sure enough to bet my life on it. The results of stem failure, I have seen some in races, are almost always catastrophic. Personally I would err on the safe side and make a badge to be epoxied on a normal stem front plate and leave the load bearing part design to the engineers at cycling component manufacturers. This would open up a whole new range of materials, I think Polished Alumide would be pretty snazzy as a badge on the stem.
