Cloning Lives! I mean, just think about Kamino and the Clone wars. Of course, also think about how they was pushed out of the Stormtroopers, even if they was more elite. If people know, you are a clone, they fear you - even if your mind is your own.
But with Trandoshan's regeneration ability, anything similarly done by medical science is not too alien, just usually needs more money and time than slapping on a working mechanical part. (As it could easily be x10 cost and x100 - x10.000 time, you understand...)
Any 3D printing would still count as either technological or medical way of doing it, it makes no difference, just a way of doing it. So, still makes it either a cybernetic implant (if not fully organic), or a fully medical genetic level "Treat Injury". The second type even counts as your own, if you spend a Force point while healing it into your body. (Helps a helluva lot against rejection...)
You can always use your own body to heal yourself, or even slightly change it cosmetically. Any bigger change in its working would count as a slight transgression, just like you changing someone else cosmetically without real need and consent. But it would always count a possibly Dark side point to change some other's body's working without full understanding, need, and consent.
And using any outside biological component - as in part of something living - would be always a slight transgression, if just for a cosmetic change, and a possibly Dark side point if it is changing the workings...
