I've done some 3D printing in uni, it depends largely on the type of 3D printing it is (SLS,DLP stereo lithography etc) some of it is not that structural and has weaknesses across the linear boundaries. If it's properly designed then I'm sure one of the processes will work for you assuming you can get a good enough contoured finished. Some of the stuff I printed was rough as a badgers arse, 0.1 steps on any curves so not really that cosmetically nice.
