Plastics have been used in medicine for decades, and nobody acts surprised when some bodypart is replaced by a plastic replica.
So why is it big news whenever that part is created using a 3d printer? I don't know, because the regular plastic parts are created using a CNC-machine, which is the exact same machine as a printer, except it begins with a solid block of plastic and removes the bits that don't look like the final part.
The only reason why you could want to use a printer instead of CNC is that a printer can create hollow shapes directly, where CNC would have to create to halves that have to be glued together.
So please, stop mentioning that a particular part was created using a 3d printer. You don't specify any other manufacturing processes, so why 3d printing, which is nothing special anyway.
